Current-enabled optical conductivity of superconductors

Subjects: subject: Superconductivity (cond-mat.supr-con)

description: In most superconductors, optical excitations require impurity scattering or the presence of multiple bands. This is because in clean single-band superconductors, the combination of particle-hole and inversion symmetries prevents momentum-conserving transitions. In this work we show how the flow of supercurrent can lead to new contributions to optical conductivity. As supercurrent breaks inversion symmetry, transitions across the superconducting gap become allowed even in clean superconductors and dominate over impurity-induced contributions for energies comparable to the gap width. The response is dependent on the nature of the underlying normal state as well as on the type of superconducting order. Through use of the screening supercurrent with controllable magnitude and direction, that arises from an external magnetic field, this enables a detailed investigation of the superconducting state and possible gap symmetry determination in unconventional superconductors for which other techniques have not been practicable.

description: Antibiotics underpin modern medicine; however, the emergence of multi-drug resistant bacterial ‘superbugs’ coupled with the absence of novel antibiotics pose a significant threat to public health. In the midst of a ‘perfect storm’, polymyxin has emerged as the last-line defence for life-threatening Gram-negative infections. Unfortunately, polymyxin-induced nephrotoxicity is dose-limiting and there is an urgent need to optimise their clinical efficacy and minimise resistance. Despite being approved for clinical use since the late 1950s, there remains a paucity of pharmacological information for the rational use of polymyxins. The data garnered in this thesis provides new information for the safer use of polymyxins, and sheds new light on the mechanisms underlying polymyxin-induced nephrotoxicity.
W and Z boson production in p-Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV

description: The W and Z boson production was measured via the muonic decay channel in proton-lead collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV at the Large Hadron Collider with the ALICE detector. The measurement covers backward ($-4.46 < y_{\rm cms} < -2.96$) and forward ($2.03 < y_{\rm cms} < 3.53$) rapidity regions, corresponding to Pb-going and p-going directions, respectively. The Z-boson production cross section, with dimuon invariant mass of $6010$ GeV/$c$ are determined. The results are compared to theoretical calculations both with and without including the nuclear modification of the parton distribution functions. The W-boson production is also studied as a function of the collision centrality: the cross section of muons from W-boson decays is found to scale with the average number of binary nucleon-nucleon collisions within uncertainties.

description: Topological defects can act as local impurities that seed cosmological phase transitions. In this paper we study the case of domain walls, and how they can affect the electroweak phase transition in the Standard Model extended with a $Z_2$-odd scalar singlet. When the transition is two-step, the early breaking of the $Z_2$ symmetry implies the formation of domain walls which can then act as nucleation sites for the second step. We develop a method based on dimensional reduction to calculate the rate of the catalyzed phase transition within the 3d theory on the domain wall surface. By comparison with the standard homogeneous rate, we conclude that the seeded phase transition is generically faster and it ultimately determines the way the phase transition is completed. We comment on the phenomenological implications for gravitational waves and baryogenesis.

description: We present a multiscale continuous Galerkin (MSCG) method for the fast and accurate stochastic simulation and optimization of time-harmonic wave propagation through photonic crystals. The MSCG method exploits repeated patterns in the geometry to drastically decrease computational cost and incorporates the following ingredients: (1) a reference domain formulation that allows us to treat geometric variability resulting from manufacturing uncertainties; (2) a reduced basis approximation to solve the parametrized local subproblems; (3) a gradient computation of the objective function; and (4) a model and variance reduction technique that enables the accelerated computation of statistical outputs by exploiting the statistical correlation between the MSCG solution and the reduced basis approximation. The proposed method is thus well suited for both deterministic and stochastic simulations, as well as robust design of photonic crystals. We provide convergence and cost analysis of the MSCG method, as well as a simulation results for a waveguide T-splitter and a Z-bend to illustrate its advantages for stochastic simulation and robust design.

description: Bacteria adhere to human tissues before establishing an infection. One adhesion mechanism uses proteins called lectins, which adhere to carbohydrates on human cell surfaces. Blocking bacterial lectins has shown potential in clinical trials for prevention of infection, making lectin inhibitors a new class of anti-bacterial therapeutic. Further development of lectin inhibitors relies on atomic structural insights that can guide inhibitor design. Computational techniques offer a route to structural information alongside experimental laboratory studies. This project presents multiple computational methodologies developed to yield structural insight and identify lectin inhibitors, techniques that will be useful for the future development of anti-adhesive therapeutics.

description: Cystic fibrosis is a life limiting disease caused by defective or deficient cystic fibrosis trans-membrane conductance regulator (CFTR) activity. The recent Food and Drug Administration and European Medicine Agency approval of lumacaftor combined with ivacaftor (Orkambi) targets patients with the F508del-CFTR. Although Kalydeco and Orkambi have only recently entered clinical use, various independent laboratories have reported unexpected off-target effects. The question remains is this breakthrough combination therapy the ‘magic-bullet’ cure CF patients have been waiting for? This project focuses on the understanding the pharmacology of ivacaftor and lumacaftor, their off-target effects such as CNS activity; and their synergistic antibacterial activity in combination with polymyxins which are used for CF inhalation therapy. The studies presented herein also shed light upon potential off-target effects that potentially impact the clinical efficacy of these drugs.

description: This thesis focused on investigating an important class of proteins that have been shown to play a role in a number of diseases, including heart disease, stroke and inflammation. Targeting these proteins with drugs is difficult, as severe side effects are commonly associated with treatment. In these studies, it was found that drugs without side effects could be developed. These drugs were able to do this by interacting with the proteins in a unique manner. The findings from this thesis suggest that targeting these proteins in a different way may be the key to avoiding side effects in future medicines.
The Challenges and Opportunities of Implementing various Electronic-Payment Projects in Commercial Bank of Ethiopia: The case of Point of Sale (POS) Terminal

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: The main objective of this study is to identify the Challenges and Opportunities of Implementing various Electronic-Payment Projects in the Commercial Bank of Ethiopia: taking Point of Sale (POS) Terminal as a case study. Mixed research design was employed and primary data was collected through questionnaires and semi-structured interviews from employees and customers of the bank and analyzed using quantitative (statistical) and qualitative methods. The finding of this study reveals that the most challenging factor to the implementation of POS terminal is network failure. Organizational factors such as lack of employees' knowledge to answer customers' questions related to POS terminal, low support and follow up, lack of coordination and cooperation between different units of the bank viz. branches, districts, and E-payment process are considered as challenges in implementing POS terminal system. Moreover, payment mode factors such as double debit of accounts for single transaction due to connectivity failures, deduction of customers account for failed transactions are amongst the challenges identified by the study. Despite the aforementioned and other challenges, the study showed that Growing acceptance of POS terminal, the Business growth of the bank, NBE's policy direction that enforce banks to adopt technological innovation, change in the society life style i.e. the ongoing digital and technology revolution are some of the major opportunities identified by the study. Efforts at improving the connectivity of the network and security of transactions is recommended in order to efficiently adopt POS terminal payment system. Moreover, the study recommended the bank to raise public awareness on the use of payment cards for transactions on POS terminals, should improve the internal communication coordination, should facilitate proper and sustainable trainings for its employees to implement POS terminal payment system proficiently

description: The singularity theorem by Hawking and Penrose qualifies Schwarzschild black-holes as geodesic incomplete space-times. Albeit this is a mathematically rigorous statement, it requires an operational framework that allows to probe the space-like singularity via a measurement process. Any such framework necessarily has to be based on quantum theory. As a consequence, the notion of classical completeness needs to be adapted to situations where the only adequate description is in terms of quantum fields in dynamical space-times. It is shown that Schwarzschild black-holes turn out to be complete when probed by self-interacting quantum fields in the ground state and in excited states. The measure for populating quantum fields on hypersurfaces in the vicinity of the black-hole singularity goes to zero towards the singularity. This statement is robust under non-Gaussian deformations of and excitations relative to the ground state. The clash of completeness cultures as exemplified with black holes is discussed.

description: Reduction of the $η$-deformed sigma model on ${\rm AdS}_5 \times {\rm S}^5$ to the two-dimensional squashed sphere $({\rm S}^2)_η$ can be viewed as a special case of the Fateev sausage model where the coupling constant $ν$ is imaginary. We show that geodesic motion in this model is described by a certain superintegrable mechanical system with four-dimensional phase space. This is done by means of explicitly constructing three integrals of motion which satisfy the $\mathfrak{sl}(2)$ Poisson algebra relations, albeit being non-polynomial in momenta. Further, we find a canonical transformation which transforms the Hamiltonian of this mechanical system to the one describing the geodesic motion on the usual two-sphere. By inverting this transformation we map geodesics on this auxiliary two-sphere back to the sausage model. This paper is a tribute to the memory of Prof. Petr Kulish.

description: Recently the Rydberg blockade effect has been utilized to realize quantum spin liquid on the kagome lattice. Evidence of quantum spin liquid has been obtained experimentally by directly measuring non-local string order. In this letter, we report a BCS-type variational wave function study of the spin liquid state in this model. This wave function is motivated by mapping the Rydberg blockade model to a lattice gauge theory, where the local gauge conservations replace the role of constraints from the Rydberg blockade. We determine the variational parameter from the experimental measurement of the Rydberg atom population. Then we compare the predictions of this deterministic wave function with the experimental measurements of non-local string order. Combining the measurements on both open and closed strings, we extract the fluctuations only associated with the closed-loop as an indicator of the topological order. The prediction from our wave function agrees reasonably well with the experimental data without any fitting parameter. Our variational wave function provides a simple and intuitive picture of the quantum spin liquid in this system that can be generalized to various generalizations of the current model.

KPZ physics and phase transition in a classical single random walker under continuous measurement

Year: 2022
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We introduce and study a new model consisting of a single classical random walker undergoing continuous monitoring at rate $γ$ on a discrete lattice. Although such a continuous measurement cannot affect physical observables, it has a non-trivial effect on the probability distribution of the random walker. At small $γ$, we show analytically that the time-evolution of the latter can be mapped to the Stochastic Heat Equation (SHE). In this limit, the width of the log probability thus follows a Family-Vicsek scaling law, $N^αf(t/N^{α/β})$, with roughness and growth exponents corresponding to the Kardar-Parisi-Zhang (KPZ) universality class, i.e $α^{\rm{1D}}_{\rm{KPZ}}=1/2$ and $β^{\rm{1D}}_{\rm{KPZ}}=1/3$ respectively. When $γ$ is increased outside this regime, we find numerically in 1D a crossover from the KPZ class to a new universality class characterized by exponents $α^{1\rm{D}}_{\text{M}}\approx 1$ and $β^{1\rm{D}}_{\text{M}}\approx 1.4$. In 3D, varying $γ$ beyond a critical value $γ^c_{\rm{M}}$ leads to a phase transition from a smooth phase that we identify as the Edwards-Wilkinson (EW) class to a new universality class with $α^{3\rm{D}}_{\text{M}}\approx1$.

title: Correlated uncertainty arithmetic with application to fusion neutronics
Creators: name: Gray, Ander
Publisher: name: University of Liverpool Repository
Year: 2023

description: his thesis advances the idea of automatic and rigorous uncertainty propagation for computational science. The aim is to replace the deterministic arithmetic and logical operations composing a function or a computer program with their uncertain equivalents. In this thesis, uncertain computer variables are labelled uncertain numbers, which may be probability distributions, intervals, probability boxes, and possibility distributions. The individual models of uncertainty are surveyed in the context of imprecise probability theory, and their individual arithmetic described and developed, with new results presented in each arithmetic. The presented arithmetic framework allows random variables to be imprecisely characterised or partially defined. It is a common situation that input random variables are unknown or that only certain characteristics of the inputs are known. How uncertain numbers can be rigorously represented by a finite numerical discretisation is described. Further, it is shown how arithmetic operations are computed by numerical convolution, accounting for both the error from the input's discretisation and from the numerical integration, yielding guaranteed bounds on computed uncertain numbers. One of the central topics of this thesis is stochastic dependency. Considering complex dependencies amongst uncertain numbers is necessary, as it plays a key role in operations. An arithmetic operation between two uncertain numbers is a function not only of the input numbers, but also how they are correlated. This is often more important than the marginal information. In the presented arithmetic, dependencies between uncertain numbers may also be partially defined or missing entirely. A major proposition of this thesis are methods to propagate dependence information through functions alongside marginal information. The long-term goal is to solve probabilistic problems with partial knowledge about marginal distributions and dependencies using algorithms which were written deterministically. The developed arithmetic frameworks can be used individually, or may be combined into a larger uncertainty computing framework. We present an application of the developed method to a radiation transport algorithm for nuclear fusion neutronics problems.

description: We use state-of-art measurements of the galaxy luminosity function (LF) at z=6, 7 and 8 to derive constraints on warm dark matter (WDM), late-forming dark matter (LFDM) and ultra-light axion dark matter (ULADM) models alternative to the cold dark matter (CDM) paradigm. To this purpose we have run a suite of high-resolution N-body simulations to accurately characterise the low mass-end of the halo mass function and derive DM model predictions of the high-z luminosity function. In order to convert halo masses into UV-magnitudes we introduce an empirical approach based on halo abundance matching which allows us to model the LF in terms of the amplitude and scatter of the ensemble average star formation rate halo mass relation of each DM model, $\langle {\rm SFR}({\rm M_{ h}},z)\rangle$. We find that independent of the DM scenario the average SFR at fixed halo mass increases from z=6 to 8, while the scatter remains constant. At halo mass ${\rm M_{h}}\gtrsim 10^{12}\,{\rm M}_\odot$ h$^{-1}$ the average SFR as function of halo mass follows a double power law trend that is common to all models, while differences occur at smaller masses. In particular, we find that models with a suppressed low-mass halo abundance exhibit higher SFR compared to the CDM results. Using deviance statistics we obtain a lower limit on the WDM thermal relic particle mass, $m_{\rm WDM}\gtrsim 1.5$ keV at $2σ$. In the case of LFDM models, the phase transition redshift parameter is bounded to $z_t\gtrsim 8\cdot 10^5$ at $2σ$. We find ULADM best-fit models with axion mass $m_a\gtrsim 1.6\cdot 10^{-22}$ eV to be well within $2σ$ of the deviance statistics. We remark that measurements at $z=6$ slightly favour a flattening of the LF at faint UV-magnitudes. This tends to prefer some of the non-CDM models in our simulation suite, although not at a statistically significant level to distinguish them from CDM.

description: Advances in cancer treatments over the last few years have resulted in improved outcomes for patients. However, to further improve survival, it is vital that cancer treatments are selected on the likelihood of response in each individual patient; decisions should no longer be based on a one-size-fits-all approach. This thesis examines the practical aspects of detecting the genetic make-up of patients and their tumours, and explores ways in which this pharmacogenomic information can inform and individualise cancer treatment with the aim of improving outcomes for cancer patients.

description: Understanding space-charge limited current density (SCLCD) is fundamentally and practically important for characterizing many high-power and high-current vacuum devices. Despite this, no analytic equations for SCLCD with nonzero monoenergetic initial velocity have been derived for nonplanar diodes from first principles. Obtaining analytic equations for SCLCD for nonplanar geometries is often complicated by the nonlinearity of the problem and over constrained boundary conditions. In this letter, we use the canonical coordinates obtained by identifying Lie-point symmetries to linearize the governing differential equations to derive SCLCD for any orthogonal diode. Using this method, we derive exact analytic equations for SCLCD with a monoenergetic injection velocity for one-dimensional cylindrical, spherical, tip-to-tip (t-t), and tip-to-plate (t-p) diodes. We specifically demonstrate that the correction factor from zero initial velocity to monoenergetic emission depends only on the initial kinetic and electric potential energies and not on the diode geometry and that SCLCD is universal when plotted as a function of the canonical gap size. We also show that SCLCD for a t-p diode is a factor of four larger than a t-t diode independent of injection velocity. The results reduce to previously derived results for zero initial velocity using variational calculus and conformal mapping.

description: We show that evolution of magnetic properties in FeS under pressure cannot be explained only in terms of a spin state transition. While uniform compression does show substantial suppression of the local magnetic moment and increase of the weights of configurations with low spin, analysis of the local spin-spin correlation function demonstrates increase of the spin itinerancy. This is related to a strong modification of the electronic structure under pressure: in the high-pressure phase FeS is in the Fermi-liquid state, while decrease of the pressure moves the system to an orbital-selective regime.
Project Risk Management Practices of Selected Chinese Building Contractors in Ethiopia
Creators: name: Chemir, Sileshi
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: This study pursued to examine the extent of application of project risk management practices such as risk identification, risk analysis, risk response strategies, risk monitoring and use of risk management tools regarding two Chinese building contractors in Ethiopia, namely CSCEC and China Wu Yi. Hence, the study was designed to assess risk management practices applied in these building companies in Ethiopia. Primary data including survey questionnaire and semi structured interview were used for the purpose of the study. The questionnaire was distributed to 30 participants and collected for quantitative analysis. The interview was held with six key informants of which four of them were tape recorded and two of them were note taken. Descriptive statistics in the form of percentages and mean score were used to analyze the quantitative data; the interview data was transcribed verbatim and analyzed qualitatively. Findings from the study revealed that risk management practices have been applied moderately in the sample projects. However, most of the findings indicated that the companies more likely relied on intuition and past experiences rather than using well established risk management processes. While there are plenty of risk management practices, tools and techniques available in literature, many projects implementation teams did not often use them. From the analysis of the data collected, it was proved that risk identification and risk management strategies were comparably the predominant risk management practices in the companies whereas risk analysis and risk monitoring were considered as the least used practices. Finally, due to the low application of risk management practices on the projects, the study concluded that there should be a need to create more awareness on project risk management practices. Additional tools and risk management practices need to be developed and tested to determine which tools works best in the different scenarios and environments of the companies.
Relativistic entropy production for quantum field in cavity

description: A nonuniformly accelerated quantum field in a cavity undergoes the coordinate transformation of annihilation and creation operators, known as the Bogoliubov transformation. This study considers the entropy production of a quantum field in a cavity induced by the Bogoliubov transformation. By classifying the modes in the cavity into the system and environment, we obtain the lower bound of the entropy production, defined as the sum of the von Neumann entropy in the system and the heat dissipated to the environment. This lower bound represents the refined second law of thermodynamics for a quantum field in a cavity and can be interpreted as the Landauer principle, which yields the thermodynamic cost of changing information contained within the system. Moreover, it provides an upper bound for the quantum mutual information to quantify the extent of the information scrambling in the cavity due to acceleration.

Search for the $Z^\prime$ boson decaying to a right-handed neutrino pair in leptophobic $\mathrm{U(1)}$ models

description: The $U(1)$ extensions of the Standard Model contain a heavy neutral gauge boson $Z^\prime$. If leptophobic, the boson can evade the stringent bounds from the dilepton resonance searches. We consider two theoretically well-motivated examples of leptophobic $U(1)$ extensions in which the $Z'$ decays to right-handed neutrinos (RHNs) with substantial branchings. The coexistence of a leptophobic $Z^\prime$ and the RHNs opens up a new possibility of searching for these particles simultaneously through the production of a $Z^\prime$ at the LHC and its decay to a RHN pair. For this decay to occur, the RHNs need to be lighter than the $Z^\prime$. Hence, we study this process in an inverse seesaw setup where the RHNs can be in the TeV range. However, in this case, they have a pseudo-Dirac nature, i.e., a RHN pair would produce only opposite-sign lepton pairs, as opposed to the Majorana-type neutrinos, which can produce both same- and opposite-sign lepton pairs. Hence, the final state we study has a same-flavour opposite-sign lepton pair plus hadronically-decaying boosted $W$ bosons. Our analysis shows that the high luminosity LHC can discover a TeV-scale leptophobic $Z^\prime$ decaying via a RHN pair in a wide range of available parameters. Interestingly, large parameter regions beyond the reach of future dijet-resonance searches can be probed exclusively through our channel.

description: As a detailed application of the BV-BFV formalism for the quantization of field theories on manifolds with boundary, this note describes a quantization of the relational symplectic groupoid for a constant Poisson structure. The presence of mixed boundary conditions and the globalization of results is also addressed. In particular, the paper includes an extension to space-times with boundary of some formal geometry considerations in the BV-BFV formalism, and specifically introduces into the BV-BFV framework a "differential" version of the classical and quantum master equations. The quantization constructed in this paper induces Kontsevich's deformation quantization on the underlying Poisson manifold, i.e., the Moyal product, which is known in full details. This allows focussing on the BV-BFV technology and testing it. For the unexperienced reader, this is also a practical and reasonably simple way to learn it.

Assessing Antecedents And Consequences Of Scope Change: The Case Of Building Construction Projects In Addis Ababa
Creators: name: Adamu, Yibekal
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: Scope changes are inevitable in construction projects. Even though literatures have acknowledged scope changes as a significant factor inhibiting construction project performance, there seems to be limited studies in this domain to systematically synthesizing preceding studies. This paper critically assessed causes of scope changes on project deliverables in the construction management field. The objectives are to analyse the severity and frequency of the causes of scope change during the implementation phase of building construction projects and to provide insights for directing further studies on building construction projects on similar and related topics in Ethiopia. The findings indicate that causes of scope changes list the causes. Though building construction projects commonly share key characteristics scope changes as a major cause of quality problems, project delays and cost overruns are not studied in Ethiopia. Therefore suggestions for future research recognizing the causes and effects of scope changes in construction project in Ethiopia, by identifying factors for scope changes and their resulting impacts on project deliverance. Thus, the analytical framework for future study is presented.
