description: The scheme previously proposed by the present authors is modified to incorporate the strong interaction by affording the direct product internal symmetry. We do not need to prepare the extra discrete space for the color gauge group responsible for the strong interaction to reconstruct the standard model and the left-right symmetric gauge model(LRSM). The approach based on non-commutative geometry leads us to presents many attractive points such as the unified picture of the gauge and Higgs field as the generalized connection on the discrete space; Minkowski space multipied by N-points discrete space. This approach leads us to unified picture of gauge and Higgs fields as the generalized connection. The standard model needs N=2 discrete space for reconstruction in this formalism. \lr is still alive as a model with the intermediate symmetry of the spontaneously broken SO(10) grand unified theory(GUT). N=3 discrete space is needed for the reconstruction of LRSM to include two Higgs bosons $ϕ$ and $ξ$ which are as usual transformed as (2,2*,0)$ and (1,3,-2) under left-handed SU(2)x right-handed SU(2)x U(1), respectively. xi is responsible to make the right handed-neutrino Majorana fermion and so well explains the seesaw mechanism. Up and down quarks have the different masses through the vacuum expectation value of phi.

The characterisation and measurement of biomedically relevant nanomaterials
Creators: name: Bell, Nia C.
Publisher: name: Imperial College London
Year: 2013

description: Nanomaterial metrology is fundamental to understanding the physical properties of nanomaterials and their environmental interactions. Particles, in the nano and sub-micrometer regimes, are attractive materials for use in biomedical applications such as drug delivery and medical imaging. In order to address concerns regarding their potential for cytotoxicity, particle characterisation before and after exposure to biologically relevant media is critical. Size is one of many particle properties that can influence their behaviour in biomedical applications, including their cellular uptake and circulation lifetime. Therefore, the sizing capabilities of three established (transmission electron microscopy (TEM), scanning mobility particle sizing (SMPS) and dynamic light scattering (DLS)) and three emerging particle sizing techniques (scanning ion occlusion sensing (SIOS), nanoparticle tracking analysis (NTA) and differential centrifugal sedimentation (DCS)) with Stober silica particles, 100 - 400 nm in diameter, as the test material, were evaluated. When exposed to biological media particles will spontaneously be coated with a film of biomolecules, predominantly proteins, which will subsequently define their biological identities. Being able to quantify and evaluate the composition of these so called "protein coronas" is key to understanding the bio-nano interface. In this study, the amount of immunoglobulin G (IgG) adsorbed onto gold particles, as a function of particle size and protein concentration, was measured, using a combination of techniques including DLS (and [Symbol appears here. To view, please open pdf attachment] -potential), NTA, DCS, and UV-Visible spectroscopy (UV-Vis) plasmonic sensing. [Symbol appears here. To view, please open pdf attachment] -potential was a good indicator of protein corona integrity, and deviations in the protein corona thicknesses measured by NTA and DCS at low protein coverage were observed. Finally, the surface chemistry of an electrospun polymer fibre scaffold was characterised using time of flight-secondary ion mass spectrometry (ToF-SIMS). The concentration of a cell adhesion enhancing peptide was measured to be linearly related to that in the bulk and its co-localisation with the polymers proven through imaging.

description: It has been suspected for nearly 50 years that clusters of galaxies contain a population of intergalactic stars, ripped from galaxies during cluster formation or when the galaxies' orbits take them through the cluster center. Support for the existence of such a population of free-floating stars comes from measurements of the diffuse light in clusters, and from recent detections of planetary nebulae with positions and/or velocities far removed from any observed cluster galaxy. But estimates for the mass of the diffuse population and its distribution relative to the galaxies are still highly uncertain. Here we report the direct detection of intergalactic stars in deep images of a blank field in the Virgo Cluster. The data suggest that approximately 10% of the stellar mass of the cluster is in intergalactic stars. We observe a relatively homogeneous distribution of stars, with evidence of a slight gradient toward M87.

Optimal liquidation in a finite time regime switching model with permanent and temporary liquidation impact
Creators: name: Wu, Nan
Publisher: name: Imperial College London
Year: 2012

description: In this thesis, we discuss the optimal liquidation problem in a finite horizon model with permanent and temporary pricing impact. We use different model set-ups including a finite time Markov diffusion model and a regime switching model with exit time. The drift and diffusion terms of the asset price are general functions depending on the state variables as well as the control. There is also a non-linear transaction cost associated with the liquidation. We verify the continuity of the value function and show that it is the unique viscosity solution of the associated HJB equation. We also propose a perturbation method to approximate the viscosity solution through a series of classical solutions with the help of the stability property of viscosity solutions. We revise the definition of viscosity solutions for the regime switching model and show that the value function is a strong-form viscosity solution. Numerical results are presented at the end to show the relationship between the optimal selling rate and the state variables.
Design and performance of photo-electrochemical reactors with Fe2O3 photo-anodes for water splitting
Creators: name: Ong, Chin Kin
Publisher: name: Imperial College London
Year: 2012

description: Sources of clean and sustainable energy are important vectors for economic growth and development. The current global energy supply depends heavily on fossil fuels, which in the future may have added costs of carbon dioxide emissions. This makes technology such as direct water splitting from harvesting solar energy in photo-electrochemical (PEC) systems potentially attractive. The principle of this technology utilises semiconductors to absorb photons of energy greater than their band gap energy, generating an electron-hole (absence of electron) pair. The hole could oxidise water to produce oxygen at the anode, while the electrons could reduce water to form hydrogen at the cathode. This project aims to design, model, characterise the performance and optimise a photo-electrochemical reactor that could efficiently harvest and store solar energy by splitting water to produce hydrogen and oxygen. α-Fe2O3 ,which is a cheap and abundant material, has shown promise as a photo-anode material, so was chosen as the photo-anode in the development of the PEC reactor. α-Fe2O3 thin films were produced by spray pyrolysis of alcoholic FeIII solutions onto fluorine-doped tin oxide film on glass. Effects of deposition precursor, post deposition heat treatment and SnIV-doping were studied. Results showed that both SnIV-doping and heat treatment were required to produce the best results (photocurrent of ca. 1-2 Am-2 at applied potential of 0.5 V vs. HgO |Hg). A charge carrier transport model was developed to understand and predict the behaviour of the Fe2O3. The model suggested that the magnitude of photocurrent was dependent on the photo-electrochemical reaction rate at the electrolyte | electrode interface, and would be limited by the intensity of illuminated photon flux. Operating the reactor at higher temperatures favoured the electrolysis process in the absence of light, but experimental results showed it was unfavourable for the net photo-generation of charge. A reactor system with a 0.1 m x 0.1 m photo-anode, Ti/Pt cathode and cation-permeable membrane was built to investigate the effects of operating parameters and operational issues of process scale up. COMSOL Multiphysics™ software was used to model the reactor and to study the reactor performance effects of fluid flow, light intensity and electrical potential drop in the thin conducting layer on glass. Results showed that at electrode area of 10-2 m2 scale, a significant electrical potential drop occurred across the photo-anode, due to its sheet resistance, resulting in non-uniform distribution of current density / rate of H2 (and O2) production (solar to hydrogen conversion efficiency of 0.16%), much of the photo-anode area being inactive. A reactor model was developed to provide a better understanding of larger-scale PEC reactor performance and was used to re-design and optimise the next reactor prototype.

description: Exceptions to the fundamental freedoms are cornerstones of the single market case law. Numerous Court judgments have elaborated upon their meaning over the past 50 years; they take centre stage in university courses across Europe. Much less discussed is a parallel development in the field of migration. More than a dozen cases have explored the meaning of the “public policy" and “public security” caveat in the supranational legislation on migration over the past decade. They exhibit instances of parallelism with free movement law as well as examples of deviation and distinction. Throughout these judgments, the Court gradually established a coherent approach. Judges insist on the uniform meaning of “public policy” and “public security” to start with, while recognising the potential for deviation and context-specific solutions in light of the wording, general scheme, objectives, and drafting history of the instrument under analysis. In the same way as the chameleon lizard adapts its colour to the environment, the interpretation of the public policy and security exception responds to the legal context. Closer inspection of the judicial practice on migration can serve as a case study on the relevant benchmarks for parallelism and divergence in the approach to public policy exceptions in other domains of Union law. In doing so, our analysis will highlight feedback loops with the restrictive twist of the case law on Union citizens. It will also introduce readers to the distinction between an abstract and individualised proportionality test which is rarely discussed by experts of EU law.
Increasing pneumococcal vaccination referral rate among high-risk adults in primary care setting
Creators: name: Tan, Chenyu
Publisher: name: No Publisher Supplied
Year: 2024

description: Purpose of Project: Vaccines are considered the greatest scientific invention in promoting public health and have saved millions of lives worldwide since their development. Streptococcus. pneumoniae is the leading cause of bacterial pneumonia, however, fewer than 25% of eligible adults younger than 65 years old receive appropriate vaccines to protect against pneumococcal infections. The purpose of this DNP project was to increase screening of all eligible patients about their pneumococcal vaccine status and making referrals as an intervention in a primary care office in Northern New Jersey. Methodology: A Pre- and Post-intervention design was used. Chart reviews were performed four weeks before and four weeks after the intervention to evaluate the impact of pneumococcal vaccine screening tool on vaccine referral rate. Charts of patients between the ages of 19 and 64 years were included. Results: One hundred and forty charts were reviewed at baseline and after the intervention was introduced at the selected site. The pre and post intervention data were compared to assess the effectiveness of the intervention. The screening rate increased from 0 to 100%. The vaccination referral rate increased significantly (χ2 = 43.36, p<.001). Implication for practice: Routinely screening all patients in the primary care setting about their pneumococcal vaccine status can help identify at risk patients and referrals can increase vaccination awareness and improve vaccination rates. Education on pneumococcal vaccines screening can be added to routine training for the office staffs to promote pneumococcal vaccine among high-risk adults and decrease the vaccine-preventable diseases.

Spatiotemporal arrayed MIMO radar
Creators: name: Commin, Henry
Publisher: name: Imperial College London
Year: 2013

description: In the last decade, Multiple Input Multiple Output (MIMO) radar has emerged as a leading candidate for stimulating major new advancement in radar theory. A fundamental challenge in MIMO radar is to identify a theoretical framework within which the radar system may be represented and analysed. In the relatively well-established field of Single Input Multiple Output (SIMO) array signal processing, this task has already been achieved using the array manifold (which is a geometric object that completely characterises the array system). A central objective of this thesis is therefore to bridge the gap between SIMO and MIMO by developing a manifold representation of the MIMO radar system. A new differential geometric framework, based on the complex Cartan matrix, is exploited in this thesis for characterising array manifold curves. New formulas are presented for recursively calculating the strictly orthonormal moving frame, U(s), and corresponding complex Cartan Matrix, C(s), for arbitrary array geometries. The circular approximation of the array manifold is derived under this new framework and compact closed-form expressions are provided for the popular uniform linear array geometry. Based on a number of approximations derived using the circular approximation of the array manifold, the performance capabilites of various popular detection and parameter estimation algorithms are investigated. The figure of merit "C" is then used to place these capabilities into the context of the theoretically ideal algorithm. The concept of a virtual SIMO array system is used as a basis for characterising the full MIMO radar configuration using a single equivalent response vector. By tracing out this response vector across the whole parameter space, a manifold is formed that fully characterises the MIMO radar system. In the important case of orthogonal transmit waveforms, the fundamental performance bounds of the MIMO radar system are studied. A space-time receiver architecture is proposed which exploits the virtual SIMO structure as part of a subspace-based joint Doppler, delay and direction of arrival (DOA) estimation framework. Due to the great computational burden of an exhaustive 3-parameter search, the joint Doppler-delay-DOA estimation is partitioned into an equivalent two-stage algorithm. The proposed approach is evaluated via computer simulation studies and shown to outperform existing methods.

Magnetic and electrical transport properties of artificial spin ice
Creators: name: Zeissler, Katharina
Publisher: name: Imperial College London
Year: 2013

description: This thesis explores the mechanisms of the magnetic reversal of permalloy artificial spin ice arrays. The main research foci include the influence of domain wall propagation on the magnetic reversal of honeycomb artificial spin ice, the low temperature behaviour of honeycomb artificial spin ice and the classification of inverse permalloy opals as three dimensional artificial spin ice. Room temperature imaging of the magnetisation configuration of the nanobars through the magnetic reversal, via scanning transmission X-ray microscopy, photoemission electron microscopy and Lorentz transmission electron microscopy, showed non random domain wall propagation through the frustrated vertices of the honeycomb artificial spin ice arrays. OOMMF simulations suggest that the origin of such non-randomness lies in the domain wall chirality. Boundary conditions necessary for domain wall injection into artificial spin ice arrays were investigated. A reduction of the edge nanobars width of 2/3 was needed to prevent random domain wall nucleation from the array edges. Electrical transport measurements showed evidence of a change in the magnetic reversal, driven by domain wall propagation, of honeycomb permalloy artificial spin ice below 15 K. The transition temperature was found to be proportional to the square of the saturation magnetisation of the ferromagnetic material used. The change in the magnetic reversal was associated with the non-random vertex domain wall positioning below the transition temperature due to the influence of vertex dipole interactions. Room temperature Lorentz transmission electron microscopy images and temperature dependent electrical transport measurements of three dimensional permalloy inverse opals showed the potential of magnetic inverse opals to act as three dimensional artificial spin ice systems.

Differentiation of murine embryonic cells towards the haematopoietic cell lineage using the HepG2 conditioned medium and encapsulation in a rotating wall vessel bioreactor
Creators: name: Fauzi, Iliana
Publisher: name: Imperial College London
Year: 2011

description: Embryonic stem cells (ESCs) are known for their unique property to be maintained almost indefinitely in an undifferentiated, proliferating state with the potential to give rise to all types of cells. Current established protocols for the culture and differentiation of ESCs are cumbersome and inefficient involving three stages: a) maintenance or expansion of undifferentiated ESCs, b) spontaneous differentiation through formation of embryoid bodies (EBs), and c) dissociation of the EBs and replating leading to the terminal differentiation to the desired lineages. One of the major challenges in the use of ESCs for cell therapy is controlling their differentiation pathways. Optimal culture conditions and requirement as well as precise differentiation mechanisms and cellular interactions within EBs are still not well characterised resulting in sub-optimal control of homogenous differentiation especially due to the formation of all three germ layers. Attempts on developing an efficient culture protocol have been widely reported in order to overcome the limitations. Recent research approaches have shown that treatment with conditioned medium derived from HepG2, a human hepatocarcinoma cell line enhances the formation of multipotent mesodermal progenitors from ESCs. This promotes a greater control of ESC differentiation in a lineage-specific fashion possibly resulting in efficient haematopoietic differentiation. In this study, we have developed an integrated, single step bioprocess for ESCs hematopoietic differentiation that: a) uses HepG2-conditioned medium (HepG2-CM), that stimulates mesoderm formation, b) facilitates three dimensional (3D) culture through encapsulation of undifferentiated ESCs in hydrogels, c) bypasses EB formation, and d) involves culture in a rotating wall vessel bioreactor that does not require passaging of the cells and is scalable and automatable. In conclusion, this thesis reports the development of a novel culture system for the efficient single-step haematopoietic differentiation of ESC resulting in a reproducible, scalable, high-intensity culture system of mESCs for ex-vivo blood manufacture.
Closed superstrings in magnetic field: instabilities and supersymmetry breaking
Creators: name: Tseytlin, A. A.
Publisher: name: arXiv
Year: 1995
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We consider a 2-parameter class of solvable closed superstring models which `interpolate' between Kaluza-Klein and dilatonic Melvin magnetic flux tube backgrounds. The spectrum of string states has similarities with Landau spectrum for a charged particle in a uniform magnetic field. The presence of spin-dependent `gyromagnetic' interaction implies breaking of supersymmetry and possible existence (for certain values of magnetic parameters) of tachyonic instabilities. We study in detail the simplest example of the Kaluza-Klein Melvin model describing a superstring moving in flat but non-trivial 10-d space containing a 3-d factor which is a `twisted' product of a 2-plane and an internal circle. We also discuss the compact version of this model constructed by `twisting' the product of the two groups in SU(2) x U(1) WZNW theory without changing the local geometry (and thus the central charge). We explain how the supersymmetry is broken by continuous `magnetic' twist parameters and comment on possible implications for internal space compactification models.

Year: 2024
Subjects: FDI, Sectoral Growth, Sustainable Economy Growth, Time Series Model.

description: Abstract

Purpose: Inconclusive results from a slew of earlier empirical research on the link between foreign direct investment (FDI) and economic development inspired the present inquiry. The paper acknowledges that past research has relied most heavily on the shaky premise that a correlation between FDI inflows and economic development can be drawn without treating the inflows separately according to sectors. Design/Methodology/Approach: The purpose of the study is based on Trading Sector (Top 10 Sectors) in India and the data is secondary data collected from the DPIIT website for the period 2022-2023. We are Using stalactitical tools like ADF Stationarity, VECM, VAR, MIDAS Originality/Value: Utilizing a period shifting boundary model with a vector autoregressive particular, this study explores the expected effect of FDI on the extension of explicit businesses in India, a non-industrial country. The study's findings are supported by da number of econometric tests, including the Johansen's cointegration test, the vector blunder rectification model, the Granger causality test, the fluctuation disintegration examination, and the drive reaction investigation. Findings: Growth and investment from outside the country, both now and in the future. According to the report, in order to attract and absorb more FDI and maintain sustained economic development, economic policymakers in India should revitalize the primary sector. Furthermore, the agricultural sector may be more dependent on the government's economic growth policies than the more volatile Trading sector.
Studies of a novel renormalization group technique for strongly correlated many body systems
Creators: name: Edwards, Khan
Publisher: name: Imperial College London
Year: 2011

description: The unusual low temperature behaviour of metals and metal alloys, such as heavy fermion systems, Mott insulators and unconventional superconductors, has been a central topic of scientific investigation for over half a century. Due to strong correlations between the many particles, the solution to most theoretical models of these systems is difficult because standard perturbation methods break down. In certain cases, non-perturbative renormalization group approaches can be used to access the low energy behaviour and take into account the effects of strong correlations. However, these methods do not work for several important and interesting classes of model. These include lattice models with finite dimension, models with impurities of high degeneracy and steady state transport through quantum dots. The aim of this thesis is therefore to develop a new and general renormalization group approach that will lend itself to wide application in models where existing techniques fail. The method explored here utilises renormalized perturbation theory (RPT) in conjunction with scaling equations and collective excitations. It is tested on the single impurity Anderson model, the paradigmatic model used to understand magnetic impurities within a non-magnetic host metal. The Anderson model is simple yet exhibits interesting features due to strong correlation, such as a single renormalized low energy scale called the Kondo temperature. This model is also well understood as it has been solved using the numerical renormalization group (NRG), which provides ample numerical data against which this new technique is compared. Finally, a preliminary study is given for this method when it is applied to a wider class of models.
The Impact of Ground Motion Uncertainty on Earthquake Loss Estimation
Creators: name: Foulser-Piggott, Roxane
Publisher: name: Imperial College London
Year: 2012

description: This thesis examines the ground motion prediction component of earthquake loss estimation (ELE) frameworks and is based on the assertion that reducing the uncertainty in ground motion prediction will result in improved accuracy of loss estimates. The objective is to obtain improved ground motion predictions by identifying and quantifying the sources of uncertainty in the predictions, with particular focus on the portion of the uncertainty that can be reduced. The work presented in this thesis starts with an examination of ground motion measures commonly used in ELE and their relative utility. The ground motion measure Arias Intensity is identified as well-suited to application in a number of problems in earthquake engineering and this along with the lack of a robust equation for its prediction, leads to the development of a new predictive equation for Arias Intensity. Next, the prediction of Arias Intensity at spatially separated locations is studied in order to develop a model for the spatial correlation of Arias Intensity so that loss estimates for spatially distributed portfolios may be obtained. Thirdly, the sources of uncertainties in the predicted values of Arias Intensity are investigated and the uncertainties are characterised and quantified in order to establish whether or not they may be reduced. The impacts of these uncertainties on the new predictive equation for Arias Intensity are also examined. The final part of the thesis focusses on the use of GIS to display the information described in the previous sections on ground motion prediction. Particular attention is given to enhancing the display of uncertainties in ground motion predictions. This thesis demonstrates that the impacts of uncertainty on ground motion predictions and therefore earthquake loss estimation are significant, making this research of particular importance in this field.

description: A possibility is discussed for experimental testing of the dark matter model supported by a classic non-Abelian SU(3) gauge (Yang-Mills) field. Our approach is based on the analysis of the motion of color-charged particles on the background of color electric and magnetic fields using the Wong equations. Estimating the magnitudes of the color fields near the edge of a galaxy, we employ them in obtaining the general analytic solutions to the Wong equations. Using the latter, we calculate the magnitude of the extra acceleration of color-charged particles related to the possible presence of the color fields in the neighbourhood of the Earth.

After an exact elimination of Gaussian degrees of freedom, the critical objects such as coupling constants, indices and susceptibility matrix are derived for all $A_k$ and spacetime dimensions $0 \leq D < 4$. There appear exceptional spacetime dimensions where the degree $k$ of the singularity $A_k$ is more strongly constrained than by the renormalizability requirement.

Publisher: name: Imperial College London

description: Rheumatic Heart Disease remains one of the most neglected cardiac conditions in children and young adults around the world. The pathogenesis is complex and remains elusive, and the clinical characteristics vary around the world. This thesis concentrates on different aspects of the disease in Egypt, where it is known to have a high incidence. The methodology included epidemiological studies in school children in Aswan and investigation of RHD in a population with history of RF, using newly developed echocardiographic criteria. Concomitantly, the pattern of immune response in RF and RHD was determined in serum and excised valves. In this series RF presents in children and young adults, as well as adults, (0.2-44 years, 10.69 ± 6.24) with polyarthritis being the most common clinical presentation (87.9%) and recurrences of RF being very common (98.2%). RHD affected 23 in 1000 school children in Aswan with over 90% of the cases being subclinical and developed in up to 69.2% of the individuals with history of RF, predominantly as mitral regurgitation. Risk factors for the development and severity of RHD were shown to be low disease awareness, non-compliance to penicillin prophylaxis or a regimen of longer than 15-days. Resistance to antibiotic regimens, including Penicillin and Vancomicin seems to lead to development and recurrences of RF in Egypt. This series showed the presence of immune activation and ongoing immunological reaction in an apparently quiescent phase of the disease with distortion of normal valvular architecture, histology and composition. This work has served to define the epidemiology, pattern of disease, immune reponse and predisposing factors in a population with no previous data, also contributing to the improvement of the echocardiographic diagnostic criteria. Standardization of the criteria will allow comparison of prevalence in different areas and improve case detection.

description: The evolution of binary systems consisting of an asymptotic giant branch star of mass equal to 3 M_sun or 5 M_sun, and a main sequence star of mass equal to 0.4 M_sun or 0.6 M_sun with orbital periods > 200 days has been followed from the onset through the late stages of the common envelope phase. Using a nested grid technique, the three-dimensional hydrodynamical simulations of an asymptotic giant branch star with radii approximately 1 A.U. indicate that a significant fraction of the envelope gas is unbound (about 31% and 23% for binaries of 3 M_sun and 0.4 M_sun, and 5 M_sun and 0.6 M_sun respectively) by the ends of the simulations, and that the efficiency of the mass ejection process is about 40%. While the original volume of the giant is virtually evacuated in the late stages, most of the envelope gas remains marginally bound on the grid. At the ends of our simulations, when the orbital decay timescale exceeds about 5 years, the giant core and companion orbit one another with a period of about 1 day (2.4 days for a binary involving a more evolved giant), although this is an upper limit to the final orbital period. For a binary of 5 M_sun and 0.4 M_sun, the common envelope may not be completely ejected.

Noncommutative/Nonlinear BPS Equations without Zero Slope Limit

description: It is widely believed that via the Seiberg-Witten map, the linearly realized BPS equation in the non-commutative space is related to the non-linearly realized BPS equation in the commutative space in the zero slope limit. We show that the relation also holds without taking the zero slope limit as is expected from the arguments of the BPS equation for the non-Abelian Born-Infeld theory. This is regarded as an evidence for the relation between the two BPS equations. As a byproduct of our analysis, the non-linear instanton equation is solved exactly.

Plugging the Gauge Fixing into the Lagrangian

description: A complete analysis of the consequences of introducing a set of holonomic gauge fixing constraints (to fix the dynamics) into a singular Lagrangian is performed. It is shown in general that the dynamical system originated from the reduced Lagrangian erases all the information regarding the first class constraints of the original theory, but retains its second class. It is proved that even though the reduced Lagrangian can be singular, it never possesses any gauge freedom. As an application, the example of $n \cdot A = 0$ gauges in electromagnetism is treated in full detail.

description: Lithium niobate (LN) based devices are widely used in integrated and nonlinear optics. This material is robust and resistive to high temperatures, which makes the LN-based devices table, but challenging to fabricate. In this work we report on the design, manufacturing and characterization of engineered dielectric media with thin film lithium niobate (TFLN) on top for the coupling and propagation of electromagnetic surface waves at the telecommunication wavelengths. The designed one-dimentional photonic crystal (1DPhC) sustains Bloch surface waves at the multilayer/air interface at 1550 nm wavelength with a propagation detected over a distance of 3 mm. The working wavelength and improved BSW propagation parameters open the way for exploration of nonlinear properties of BSW based devices. It is also expected that these novel devices will modify BSW propagation and coupling by external thermal/electrical stimuli due to the improved quality of the TFLN top layer of 1DPhC.

On the properties of point defects in silicon nanostructures from ab initio calculations
Creators: name: Corsetti, Fabiano
Publisher: name: Imperial College London
Year: 2012

description: In this thesis we apply a variety of computational methods based on density-functional theory (DFT) to the study of defect centres in bulk silicon and silicon nanostructures. Firstly, we discuss the system-size convergence of point defect properties in the supercell method for deep-level defects in bulk silicon; we consider both the vacancy and gold impurity. For the vacancy, we investigate systematically the main contributions to the finite size error that lead to the well-known slow convergence with respect to system size of defect properties, and demonstrate that different properties of interest can benefit from the use of different k-point sampling schemes. We also present a simple and accurate method for calculating the potential alignment correction to the valence band maximum of charged defect supercells by using maximally-localised Wannier functions, and show that the localised view of the electronic structure provided by them gives a clear description of the nature of the electronic bonding at the defect centre. For the gold impurity, we show that the system becomes a non-spin-polarised negative-U centre due to the effect of Jahn-Teller distortion, thus providing a simple explanation for the absent electron paramagnetic resonance signal for gold in silicon. The calculated transition levels are found to be in excellent agreement with experimental measurements. We then investigate the segregation of arsenic impurities in silicon close to an interface with amorphous silica. We employ a multiscale approach, generating a realistic disordered interface structure from Monte Carlo simulation, with a continuous random network model of the system parametrised from DFT. We calculate the segregation energy using DFT for a large number of substitutional sites encompassing all the oxidation states of silicon, and show that the results can be understood with a minimal model based only on the local strain and volume of the defect site.

description: The one-loop effective action of QED obtained by Euler and Heisenberg and by Schwinger has been expressed by an asymptotic perturbative series which is divergent. In this letter we present a non-perturbative but convergent series of the effective action. With the convergent series we establish the existence of the manifest electric-magnetic duality in the one loop effective action of QED.

title: Short-distance constraints on the hadronic light-by-light contribution to the muon g-2
Creators: name: Laub, Laetitia
Publisher: name: Universität Bern
Year: 2021
Subjects: subject: 530 Physics

description: The aim of this work is to investigate the information available from perturbative QCD to constrain the hadronic light-by-light contribution to $(g-2)_\mu$ and to implement it in a way that is compatible with the dispersive description.

The first regime of interest is the one where three photon virtualities are large. Because the external photon is soft in the $g-2$ kinematics, an operator product expansion in presence of an external electromagnetic field needs to be used. The leading order in this expansion corresponds to the usual massless quark loop. In this work, it is shown that the non-perturbative corrections are small and that the $\alpha _s$-correction is negative and amounts to about 10\% of the quark loop. The second interesting regime is the one where two photon virtualities are much larger than the third. This leads to the so-called Melnikov-Vainshtein constraint.

A way to satisfy the short-distance constraints using heavy pseudoscalars is then presented. This is done using a large-$N_c$ inspired Regge model for the transition form factors of the radially excited pseudoscalars. The contribution of the heavy pseudoscalars is then matched to the quark loop and its first gluonic correction in order to reduce the model-dependence of our estimation.

With the recent results from Fermilab, the discrepancy between the experimental and theoretical determinations of the anomalous magnetic moment of the muon has been pushed to $4.2\sigma$. In order to reach the $5\sigma$-threshold, the experimental and theoretical uncertainties need to be reduced further.
