description: Scanning tunneling microscope (STM) is a powerful tool for studying the structural and electronic properties of materials at the atomic scale. The combination of low temperature and high magnetic field for STM and related spectroscopy techniques allows us to investigate the novel physical properties of materials at these extreme conditions with high energy resolution. Here, we present the construction and the performance of an ultrahigh vacuum 3He fridge-based STM system with a 7 Tesla superconducting magnet. It features a double deck sample stage on the STM head so we can clean the tip by field emission or prepare a spin-polarized tip in situ without removing the sample from the STM. It is also capable of in situ sample and tip exchange and preparation. The energy resolution of scanning tunneling spectroscopy at T = 310 mK is determined to be 400 mK by measuring the superconducting gap with a niobium tip on a gold surface. We demonstrate the performance of this STM system by imaging the bicollinear magnetic order of $Fe_{1+x}Te$ at T=5K.

description: We report results of a three dimensional, high resolution (up to 512^3) numerical investigation of supersonic compressible magnetohydrodynamic turbulence. We consider both forced and decaying turbulence. The model parameters are appropriate to conditions found in Galactic molecular clouds. We find that the dissipation time of turbulence is of order the flow crossing time or smaller, even in the presence of strong magnetic fields. About half the dissipation occurs in shocks. Weak magnetic fields are amplified and tangled by the turbulence, while strong fields remain well ordered.

description: Liquid argon-based scintillation detectors are important for dark matter searches and neutrino physics. Argon scintillation light is in the vacuum ultraviolet region, making it hard to be detected by conventional means. Polyethylene naphthalate (PEN), an optically transparent thermoplastic polyester commercially available as large area sheets or rolls, is proposed as an alternative wavelength shifter to the commonly-used tetraphenyl butadiene (TPB). By combining the existing literature data and spectrometer measurements relative to TPB, we conclude that the fluorescence yield and timing of both materials may be very close. The evidence collected suggests that PEN is a suitable replacement for TPB in liquid argon neutrino detectors, and is also a promising candidate for dark matter detectors. Advantages of PEN are discussed in the context of scaling-up existing technologies to the next generation of very large ktonne-scale detectors. Its simplicity has a potential to facilitate such scale-ups, revolutionizing the field.

description: We first review reasons why dark matter is an interesting issue in connection with star clusters. Next we consider to what extent the presence of dark matter is consistent with their dynamics and structure. We review various model-dependent and model-independent methods which have been applied to two well studied clusters, NGC 6397 and 47 Tuc. We suggest that about half of the mass in each object is still unobserved, possibly in the form of a mixture of low-mass stars and white dwarfs.

description: Thin films of rare-earth monopnictide semimetals are expected to turn into semiconductors due to quantum confinement effect, which lifts the overlap between electron pockets at Brillouin zone edges and hole pockets at the zone center. Instead, taking non-magnetic LaSb as an example, we find the emergence of a quantum spin Hall insulator phase in LaSb(001) films as the thickness is reduced to 7, 5, or 3 monolayers. This is attributed to a strong quantum confinement effect on the in-plane electron pockets, and the lack of quantum confinement on the out-of-plane pocket in reciprocal space projected onto zone center, leading to a band inversion. Spin-orbit coupling opens a sizeable non-trivial gap in the band structure of the thin films. Such effect is shown to be general in rare-earth monopnictides and may lead to interesting phenomena when coupled with the 4f magnetic moments present in other members of this family of materials.

description: The invention relates to a compact, high-efficiency energy generation system employing

quantum-entangled hydrogen isotope fusion within nanoscale confinement structures. It

comprises a multiplicity of individually controlled fusion traps formed at nanometer scale, each

configured to receive pre-entangled pairs of hydrogen isotopes such as protium, deuterium, or

tritium. Each trap is stimulated by attosecond-timed electromagnetic resonance pulses to induce

fusion via quantum tunneling. Fusion events are monitored and optimised through an integrated

artificial intelligence (AI) control layer that ensures only coherence-validated, phase-aligned

pairs are activated. The system includes capacitive and inductive energy reclamation

components, and operates in inert gas environments without vacuum chambers or magnetic

plasma confinement. This allows for safe, clean, modular, and radiation-free energy generation

suitable for terrestrial, mobile, and space-based applications. Present-day embodiments yield

1–3 MW electrical output in ~2 m³ volume. Future embodiments scale output to 16–17 MW per

~1 m³ module with improved entanglement routing, phase tuning, and quantum AI

synchronization.

description: To obtain Bell statistics from hybrid systems composed of finite- and infinite-dimensional systems, we propose a hybrid measurement scheme, in which the continuous mode is measured using the generalized pseudospin operators, while the finite (two)-dimensional system is measured in the usual Pauli basis. Maximizing the Bell expression with these hybrid measurement settings leads to the violations of local realism in hybrid system which is referred to as hybrid nonlocality. We demonstrate the utility of our strategy in a realistic setting of cavity quantum electrodynamics, where an atom interacts resonantly with a single mode of an electromagnetic field under the Jaynes-Cummings Hamiltonian. We dynamically compute the quenched averaged value of hybrid nonlocality in imperfect situations by incorporating disorder in the atom-cavity coupling strength. In the disordered case, we introduce two kinds of measurement scenarios to determine the Bell statistics -- in one situation, experimentalists can tune the optimal settings according to the interaction strength while such controlled power is absent in the other case. In contrast to the oscillatory behavior observed in the ordered case, the quenched averaged violation saturates to a finite value in some parameter regimes in the former case. We also examine the connection between Wigner negativity and hybrid nonlocality.

description: We present and test a general-purpose code, called PPASPH, for evolving self-gravitating fluids in astrophysics, both with and without a collisionless component. In PPASPH, hydrodynamical properties are computed by using the SPH (Smoothed Particle Hydrodynamics) method while, unlike most previous implementations of SPH, gravitational forces are computed by a PP (Particle-Particle) approach. another important feature of this code is that hydrodynamics equations optionally include the correction terms appearing when $h(t,\br)$ is not constant. Our code has been implemented by using the data parallel programming model on CM5(CM). PPASPH has been applied to study the importance of adaptative smoothing correction terms on the entropy conservation. We confirm Hernquist's (1993) interpretation of the entropy violation observed in previous SPH simulations as a result of having neglected these terms. An improvement on the entropy conservation is not found by merely considering larger numbers of particles or different $N_S$ choices. The correct continuum description is only obtained if the $\bn h$ correction terms are included. Otherwise, the entropy conservation is always rather poor as compared to that found for the total energy.

Unextendibility, uncompletability, and many-copy indistinguishable ensembles

Publisher: name: arXiv
Year: 2023
Subjects: subject: Quantum Physics (quant-ph)

description: In this work, we explore the notions unextendible product basis and uncompletability for operators which remain positive under partial transpose. Then, we analyze their connections to the ensembles which are many-copy indistinguishable under local operations and classical communication (LOCC). We show that the orthogonal complement of any bipartite pure entangled state is spanned by product states which form a nonorthogonal unextendible product basis (nUPB) of maximum cardinality. This subspace has one to one correspondence with the maximum dimensional subspace where there is no orthonormal product basis. Due to these, the proof of indistinguishability of a class of ensembles under LOCC in many-copy scenario becomes simpler. Furthermore, it is now clear that there are several many-copy indistinguishable ensembles which are different construction-wise. But if we consider the technique of proving their indistinguishability property under LOCC, then, for many of them it can be done using the general notion of unextendible product basis. Explicit construction of the product states, forming nUPBs is shown. Thereafter, we introduce the notion of positive partial transpose uncompletability to unify different many-copy indistinguishable ensembles. We also report a class of multipartite many-copy indistinguishable ensembles for which local indistinguishability property increases with decreasing number of mixed states.

Sustainable energy management of water distribution systems through optimised pump scheduling
Creators: name: Menke, Ruben
Publisher: name: Imperial College London
Year: 2017

description: Climate change, caused by anthropogenic greenhouse gas emissions, is one of the most important issues of our time. It is often overlooked that up to 5% of a cities electrical energy consumption is required to pump water in the water distribution system. This thesis describes how pump scheduling can contribute to a more sustainable energy management of water distribution systems. The analysis is enabled though a new convex formulation of the pump scheduling problem, which provides theoretical optimality bounds, a requirement for the comparison of different energy management strategies. The problem formulation is then expanded to include variable speed pumps. The first energy management method investigated is the provision of demand response to the grid by adapting pump operating schedules. Demand response from water distribution systems is shown to provide reserve energy at lower cost and with less than half of the greenhouse gas emissions 240gCO2e/kWh of the competing technologies. Installing variable speed pumps in a network is shown to increase the possible applications of demand response and increase the revenue potential. Next, the trade-offs between cost and emission reduction are analysed in a range of energy supply scenarios in the UK, in the current grid as well as possible future scenarios. It is found that greenhouse gas emission cost must rise significantly, above £100 t/CO2, before affecting scheduling decisions. Furthermore, it is shown that the pump utilisation rate, the share of time the pump operates, is key to profit from possible changes in the energy supply. Finally, the operating schedule of pumps powered in part by an on-site wind turbine is optimised. This analysis calculates the cost of uncertainty in the wind power forecast in renewable energy generation. A stochastic optimisation method is presented that reduces the cost of uncertainty.

Our visualization tool targets both users and scholars. Practitioners who employ hexmeshes for Finite Element Analysis, can readily check mesh quality and assess its usability for simulation. Researchers involved in mesh generation may use HexaLab to perform a detailed analysis of the mesh structure, isolating weak points and testing new solutions to improve on the state of the art and generate high quality images. To this end, we support a wide variety of visualization and volume inspection tools. Our system offers also immediate access to a repository containing all the publicly available meshes produced with the most recent techniques for hexmesh generation. We believe HexaLab, providing a common tool for visualizing, assessing and distributing results, will push forward the recent strive for replicability in our scientific community.

description: Strong coupling between single qubits is crucial for quantum information science and quantum computation. However, it is still challenged, especially for single solid-state qubit. Here, we propose a hybrid quantum system, consisting of a coplanar waveguide (CPW) resonator weakly coupled to a single nitrogen-vacancy spin in diamond and a yttrium-iron-garnet (YIG) nanosphere holding Kerr magnons, to realize strong long-distance spin-spin coupling. With a strong driving field on magnons, the Kerr effect can squeeze magnons, and {thus the coupling between the CPW resonator and the sequeezed magnons is exponentially enhanced}, which produces two cavity-magnon polaritons, i.e., the high-frequency polariton (HP) and low-frequency polariton (LP). When the enhanced cavity-magnon coupling {approaches} the critical value (i.e., the frequency of the LP becomes zero), the spin is fully decoupled from the HP, while the coupling between the spin and the LP is significantly improved. In the dispersive regime, a strong spin-spin coupling mediated by the LP is achieved with accessible parameters. Our proposal indicates that the critical cavity-magnon polarition is a potential interface to realize strong spin-spin coupling and manipulates remote solid spins.

Are Gamma Ray Bursts due to Rotation Powered High Velocity Pulsars in the Halo ?

Publisher: name: arXiv
Year: 1995
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The BATSE experiment has now observed more than 1100 gamma-ray bursts. The observed angular distribution is isotropic, while the brightness distribution of bursts shows a reduced number of faint events. These observations favor a cosmological burst origin. Alternatively, very extended Galactic Halo (EGH) models have been considered. In the latter scenario, the currently favored source of gamma-ray bursts involves high velocity pulsars ejected from the Galactic disk. To be compatible with the observed isotropy, most models invoke a sampling distance of 300 kpc, a turn-on delay of 30 Myrs, and a source life time of about 1 Gyr. We consider the global energy requirements of such models and show that the largest known resource. rotational kinetic energy, is insufficient by orders of magnitude to provide the observed burst rate. More exotic energy sources or differently tuned pulsar models may be able to get around the global energy constraint but at the cost of becoming contrived. Thus, while extended halo models are not ruled out, our arguments place a severe obstacle for such models and we encourage proponents of EGH models to clearly address the issue of global energetics.

description: The discovery of the first naturally occurring high gain hydrogen recombination line (HRL) maser, in the millimeter and submillimeter spectrum of the emission line star MWC349, requires an expansion of current paradigms about HRLs. In this paper we re-examine in general the physics of non-LTE populations in recombining hydrogen and specify the conditions necessary for high-gain masing and lasing in HRLs. Saturation of masing recombination lines is a critical consideration. We draw attention to another non-LTE phenomenon active in hydrogen: the overcooling} of populations. Observationally the HRL overcooling might manifest itself as an anomalously weak emission recombination line, or as a ``dasar,'' that is, an anomalously strong absorption line. We briefly discuss the prospects of detecting hydrogen masers, lasers and dasars in several classes of galactic and extragalactic objects, including compact HII regions, Be or Wolf-Rayet stars, and AGNs.

description: The problem of measuring the solar age by means of helioseismology hasbeen recently revisited by Guenther & Demarque (1997) and by Weiss & Schlattl (1998). Different best values for $t_{\rm seis}$ and different assessment of the uncertainty resulted from these two works. We show that depending on the way seismic data are used, one may obtain the value $t_{\rm seis}\approx 4.6$ Gy, close to the age of the oldest meteorites, $t_{\rm met}=4.57$ Gy, like in the first paper, or above 5 Gy like in the second paper. The discrepancy in the seismic estimates of the solar age may be eliminated by assuming higher than the standard metal abundance and/or an upward revision of the opacities in the solar radiative interior.We argue that the most accurate and robust seismic measure of the solar age are the small frequency separations, $D_{\ell,n}=ν_{l,n}-ν_{\ell+1,n-1}$, for spherical harmonic degrees $\ell=0,2$ and radial orders $n\gg\ell$.The seismic age inferred by minimization of the sum of squared differences between the model and the solar small separations is $t_{\rm seis}=4.66\pm0.11$, a number consistent with meteoritic data.Our analysis supports earlier suggestions of using small frequency separations as stellar age indicators.

Star and Cluster Formation in the Large Magellanic Cloud

description: A great burst of cluster formation increased the rate at which open clusters were formed in the Large Magellanic Cloud 3-5 Gyr ago by at least an order of magnitude. On the other hand the rate of star formation ~ 4 Gyr appears to have increased by a factor of only 2-4. This shows that the rate of cluster formation is not a good tracer of the rate at which stars are formed. Normalized to the same rate of star formation, the Large Cloud is presently forming / 600 times more star clusters than the Local Group dwarf irregular IC 1613. The high rate of cluster formation in merging gas-rich galaxies suggests that strong shocks might favor the formation of clusters.

description: We prove that the exactness of direct limits in an abelian category with products and an injective cogenerator J is equivalent to a condition on J which is well-known to characterize pure-injectivity in module categories, and we describe an application of this result to the tilting theory. We derive our result as a consequence of a more general characterization of when inverse limits in the Eilenberg-Moore category of a monad on the category of sets preserve regular epimorphisms.

description: The white dwarf luminosity function has proven to be an excellent tool to study some properties of the galactic disk such as its age and the past history of the local star formation rate. The existence of an observational luminosity function for halo white dwarfs could provide valuable information about its age, the time that the star formation rate lasted, and could also constrain the shape of the allowed Initial Mass Functions (IMF). However, the main problem is the scarce number of white dwarfs already identified as halo stars. In this Letter we show how an artificial intelligence algorithm can be succesfully used to classify the population of spectroscopically identified white dwarfs allowing us to identify several potential halo white dwarfs and to improve the significance of its luminosity function.

description: Ayyer and Linusson studied correlations in the multispecies TASEP on a ring (Trans AMS, 2017) using a combinatorial analysis of the multiline queues construction defined by Ferrari and Martin (AOP, 2008). It is natural to explore whether an analogous application of appropriate multiline queues could give similar results for the partially asymmetric case. In this paper, we solve this problem of correlations of adjacent particles on the first two sites in the multispecies PASEP on a finite ring. We use the multiline processes defined by Martin (EJP, 2020), the dynamics of which also depend on the asymmetry parameter $q$, to compute the correlations.
Frailty assessment in acute care
Creators: name: Soong, John
Publisher: name: Imperial College London
Year: 2017

description: Introduction For some people, ageing is associated with the experience of increased co-morbidity, functional impairment, poor resilience and heightened vulnerability to external stressors, resulting in reduced lifespan as well as health-span. This frailty phenomenon poses challenges to health care systems in the form of increased patient complexity and resource utilisation. The acute care setting, characterised by time-pressure and high patient turn-over, is under strain and struggles to recognise and subsequently reliably intervene, to prevent, reverse or halt the decline of this vulnerable cohort. Methods This mixed-methods study probes existing evidence and ‘real-world’ processes with a systematic review of frailty assessments developed or validated in the acute care setting and a survey of contemporaneous clinical practice in London Acute Medical Units. Content validation and understanding of contextual factors for ideal frailty assessment in acute care is explored using Delphi consensus and Focus Group methodology respectively. The resultant model is developed on existing retrospective national Hospital Episode Statistics data, and prospectively tested on observational data in a local Acute Medical Unit setting. Results Existing frailty scores are preponderantly biophysical in nature, and have poor predictive power for adverse outcomes in the acute care setting. In clinical practice, single-dimension assessment tools predominate. Frailty syndromes and previous high resource utilisation in the form of a simple, clinically relevant tool useful to the multidisciplinary team gain consensus as optimal assessment for the setting. Retrospective testing of the frailty model displays moderate predictive powers for adverse events (inpatient mortality, emergency readmission and institutionalisation) and prospective testing provides concurrent (Frailty Index, Age, Co-Morbidity) and comparative predictive validity (Frailty Index, Co-Morbidity, admission National Early Warning Score) with existing risk stratification models in this setting. Conclusions A risk prediction model based on frailty syndromes and previous high resource utilisation is a valid, feasible and useful for the acute care setting.

On Mirror Symmetry for Fano varieties and for singularities
Creators: name: Petracci, Andrea
Publisher: name: Imperial College London
Year: 2017

description: In this thesis we discuss some aspects of Mirror Symmetry for Fano varieties and toric singularities. We formulate a conjecture that relates the quantum cohomology of orbifold del Pezzo surfaces to a power series that comes from Fano polygons. We verify this conjecture in some cases, in joint work with A. Oneto. We generalise the Altmann–Mavlyutov construction of deformations of toric singularities: from Minkowski sums of polyhedra we construct deformations of affine toric pairs. Moreover, we propose an approach to the study of deformations of Gorenstein toric singularities of dimension 3 in the context of the Gross–Siebert program. We construct deformations of polarised projective toric varieties by deforming their affine cones. This method is explicit in terms of Cox coordinates and it allows us to give explicit equations for a construction, due to Ilten, which produces a deformation between two toric Fano varieties when their corresponding polytopes are mutation equivalent. We also provide examples of Gorenstein toric Fano 3-folds which are locally smoothable, but not globally smoothable.

Controlling turbulent boundary layers through the actuation of a compliant structure
Creators: name: Bird, James William
Publisher: name: Imperial College London
Year: 2016

description: The control of turbulent boundary layers through spanwise wall forcing has been the subject of extensive numerical and experimental investigation in recent years. It has been shown that the benefits of drag reduction and potential power saving are enhanced when the forcing takes the form of a streamwise travelling wave of spanwise velocity. When this wave has a certain non-dimensional frequency and wavenumber, large turbulent skin-friction drag reductions of almost 50% and potential net power savings of 38% can be achieved. While there are numerous direct numerical simulations (DNS) showing these trends, an experimental validation was lacking for boundary layer flows. The work presented details the design and manufacture of an active surface, capable of discretising these complex waveforms to bring about turbulent flow-control in a wind tunnel experiment. Through the optimal design of a compliant structure, based on the Kagome lattice geometry, an adaptive framework was developed which is capable of discretising waveforms through controlled local deformation. By combining this compliant structure with a pre-tensioned membrane, an active surface is produced. The surface, 3 m in length, is then driven pneumatically, producing surface travelling waves of variable wavenumber and phase velocity. Photogrammetric and vibrometer measurements of the static and dynamic performance of actuated surface are presented. Constant temperature anemometer measurements of the boundary layer were taken with and without the active surface applying forcing. A linear interpolation of the viscous sub-layer was performed to assess changes in wall shear-stress. For certain forcing parameters, a drag reduction of 20% was measured.
Minimum relaxation n-body simulations using orthogonal series force computation
Creators: name: Weinberg, Martin D.
Publisher: name: arXiv
Year: 1995
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: This report describes a modification of the orthogonal function Poisson solver for n-body simulations that minimizes relaxation caused by small particle number fluctuations. With the standard algorithm, the noise leading to relaxation can be reduced by making the expansion basis similar to the particle distribution and by carefully choosing the maximum order in the expansion. The proposed algorithm accomplishes both tasks simultaneously while the simulation is running. This procedure is asymptotically equivalent to expanding in an orthogonal series which is matched to the distribution to start and truncating at low order. Because the modified algorithm adapts to a time-evolving distribution, it has advantage over a fixed basis. The required changes to the standard algorithm are minor and do not affect its overall structure or scalability. Tests show that the overhead in CPU time is small in practical applications. The decrease in relaxation rate is demonstrated for both axisymmetric and non-axisymmetric systems and the robustness of the algorithm is demonstrated by following the evolution of unstable generalized polytropes. Finally, the empirically based moment analysis which leads to the uncorrelated basis is an ideal tool for investigating structure and modes in n-body simulations and an example is provided.

Deciphering type IV pilus biology in the Gram-positive opportunistic pathogen Streptococcus sanguinis
Creators: name: Gurung, Ishwori
Publisher: name: Imperial College London
Year: 2017

description: Type IV pili (Tfp) are the paradigm of a large group of diverse and functionally versatile nanomachines, intensively studied in Gram-negative bacteria. However, details regarding the molecular mechanisms of Tfp biogenesis and/or mediated functions are still unclear. Thus, owing to the inherent lack of outer cell wall in Gram-positive bacteria, my PhD has focused on molecular characterisation of Tfp in a simpler such bacterium Streptococcus sanguinis. My work has shown that the naturally competent S. sanguinis produces bona fide retractable Tfp enabling twitching motility, but dispensable for competence. Unlike Gram-negative Tfp, we show that S. sanguinis Tfp are unusual since they are composed of two pilin proteins, a feature likely to be shared by other Gram-positive Tfp-expressing species. All the genes involved in Tfp biology in S. sanguinis are found within a pil locus encoding 21 proteins. A systematic genetic study highlighted that 10 proteins only are required for Tfp biogenesis, whilst another four modulate twitching motility. To enhance genetic manipulation of S. sanguinis, a markerless mutagenesis strategy was devised enabling us to make various mutations in situ, which helped us characterise some of these proteins further. Via this methodology, the last six genes of the pil locus were found to be completely dispensable for Tfp biology. To get an overall structural picture of Tfp in S. sanguinis, the structure of one of the major pilins (PilE1) was determined by NMR. Moreover, three pilin-like proteins within the pil locus were found to be minor Tfp components. Collectively, my work has established S. sanguinis as a robust Gram-positive model organism for studying Tfp, which paves way for interesting future studies.
