A spectroscopic study of strain-balanced InGaAs/GaAsP quantum well structures as absorber materials for hot carrier solar cells
Creators: name: Hirst, Louise
Publisher: name: Imperial College London
Year: 2012

description: In this thesis, five intrinsic loss mechanisms which fundamentally limit solar energy conversion efficiency are identified. The three dominant mechanisms are thermalisation loss, below Eg loss and Boltzmann loss. Targeting these three losses through alternative device design is the only way substantial efficiency enhancement might be achieved. The hot carrier solar cell targets these dominant mechanisms and hence has a theoretical limiting efficiency, under maximum solar concentration, in excess of 80%. Despite clear efficiency advantages, a hot carrier solar cell has never been experimentally demonstrated because two key development challenges remain: energy selective contacts and absorber materials which maintain a hot carrier distribution under realistic levels of incident solar irradiation. In this study, strain-balanced InGaAs/GaAsP QW structures with a range of QW parameters were characterised spectroscopically in order to determine the suitability of this material system as a hot carrier absorber. In a deep, wide well sample, a temperature gradient between the carrier distribution and the surrounding lattice of 150 K was demonstrated using continuous wave photoluminescence spectroscopy. This technique was also used to calculate a thermalisation coefficient for each sample, allowing for comparison with other hot carrier studies. Time resolved photoluminescence measurements were used to identify cooling pathways occurring in this material system. Bi-exponential cooling behaviour was observed, indicating that two different mechanisms with different characteristic cooling lifetimes were dominating carrier cooling. In the deep, wide well sample it was determined that peak LO phonon distribution temperatures of at least 500 K above that of the surrounding lattice would be required to produce the observed carrier cooling.

description: We report the magnetotransport properties of HoSb, a semimetal with antiferromagnetic ground state. HoSb shows extremely large magnetoresistance (XMR) and Shubnikov-de Haas (SdH) oscillation at low temperature and high magnetic field. Different from previous reports in other rare earth monopnictides, kinks in $ρ(B)$ and $ρ_{xy}(B)$ curves and the field dependent resistivity plateau are observed in HoSb, which result from the magnetic phase transitions. The fast Fourier transform analysis of the SdH oscillation reveals the split of Fermi surfaces induced by the nonsymmetric spin-orbit interaction. The Berry phase extracted from SdH oscillation indicates the possible nontrivial electronic structure of HoSb in the presence of magnetic field. The Hall measurements suggest that the XMR originates from the electron-hole compensation and high mobility.

subject: FOS: Physical sciences

description: Nuclear entanglement is a flagship in the interdisciplinary direction of nuclear physics and quantum information science. Spin entanglement, a special kind of nuclear entanglement, is ubiquitous in nuclear structures and dynamics. Based on the idea of quantum state tomography, the problem of experimental determination of spin entanglement of two-nucleon pure states is studied directly within the scope of nuclear physics. It is shown that the amount of spin entanglement can be obtained by measuring three spin polarizations of one nucleon in polarization experiments. The errors from imperfect preparation of nucleon pairs are also analyzed. This work not only complements the existing literature of nuclear entanglement but also provides new opportunities for nuclear physics with polarized particles.

Synthesis, Characterization and Physical-Chemical Properties of Room Temperature Ionic Liquids with a variety of Cations, Paired With Bis(trifluoromethylsulfonyl)imide Anion
Creators: name: Ab Rani, Mohd Azri
Publisher: name: Imperial College London
Year: 2012

description: This thesis contains two main parts: synthesis of ionic liquids and their precursors, and measurement of the physical-chemical properties of the ionic liquids synthesized. The first part describes a study of the successful synthesis of 22 ionic liquids and their precursors, including 12 novel compounds ([RC1im][X] and [RC1pyrr][X] where R=C4, C5, C2OC2C1, SiOSiC1, (SiO)2SiC1, X=Cl, NTf2). In this study a reliable and rigorous method for the synthesis of ionic liquids in a good yield and high quality was developed. The ionic liquids synthesized contained a variety of cations containing alkyl, ether, disiloxane and trisiloxane side chains. All the ionic liquids contained the bis(trifluoromethylsulfonyl) imide anion. The second part of the project was the study of the physical-chemical properties of the ionic liquids synthesized. Understanding these physical-chemical properties is required before any applications can proceed. The polarity, density, thermal stability, viscosity, conductivity and diffusion coefficients of the ionic liquids were measured and described. The Kamlet-Taft [Symbol appears here. To view, please open pdf attachment] values of the ionic liquids are dominated by the nature of cations whereas the β values are controlled by the nature of the anion. The polarizability values, π* were lowered by having siloxane side chains in comparison to alkyl and ether side chains. Ionic liquids with an ether side chain showed the highest density of those studied. The thermal stabilities of the ionic liquids followed the order alkane > ether > disiloxane > trisiloxane substituent. From a transport property point of view, it can be concluded that the less viscous the ionic liquids, the faster the movement and higher the diffusion coefficient of the ions.

description: Global N=2 supersymmetry in four dimensions with a gauged central charge is formulated in superspace. To find an irreducible representation of supersymmetry for the gauge connections a set of constraints is given. Then the Bianchi identities are solved subject to this set of constraints. It is shown that the gauge connection of the central charge is a N=2 vector multiplet. Moreover the Bogomol'nyi bound of the massive particle states is studied.

Finite Temperature Effects in the Supergravity Dual of the N=1* Gauge Theory

description: We consider the supergravity dual of the N=1* theory at finite temperature by applying the Polchinski-Strassler construction to the black D3 brane solution of Type IIB supergravity. At finite temperature the 5-brane probe action is minimized when the probe falls to the horizon, although metastable minima with r>>r_H persist for a range of temperatures. Thermal effects on the 3-form source for the hypermultiplet mass m and its order m^2 back reaction on the other fields of the IIB theory are computed. We find unique solutions which are regular at the horizon and have the correct behavior on the boundary. For fixed temperature T, the horizon shrinks for increasing m^2 suggesting that there is a critical temperature separating the system into high and low temperature phases. In the high temperature phase 5-branes are unnecessary since there are no naked singularities. Using the order m^2 correction to the horizon area we calculate the correction to the entropy to be ΔS =-0.1714N^2m^2T, which is less than the free field result.

Development and application of advanced thermodynamic molecular description for complex reservoir fluids containing carbon dioxide and brines
Creators: name: Dufal, Simon
Publisher: name: Imperial College London
Year: 2013

description: This thesis contains a study of the thermodynamic properties of complex reservoir fluids. The focus of this work is the development of an equation of state and molecular models to describe the phase behaviour of the different components of the reservoir fluids that may be encountered in the context of CO2 injection into geological formations suitable for storage, e.g., saline aquifers or depleted hydrocarbon reservoirs, together with that of mixtures of these components that may be encountered. The major constituents of these reservoir fluids are the injected gas (CO2, which may contain some impurities), alkanes and various other hydrocarbons from natural gas or crude oil, water and salts. The first task is to ensure that the method selected (the SAFT-VR Mie equation of state) to model those fluids can provide an accurate description of the simplest of the fluids encountered, CO2 and hydrocarbons. A crucial aspect of this concerns a detailed examination of the procedure for searching the highly degenerate model-parameter space to obtain the best models for each fluid. The suitability of the method is also assessed by studying other simple fluids, as a means to test the range of validity of the models developed. Once the method has been validated for a wide range of relatively simple fluids, the next step is to study more-complex fluids including, in particular, water. Water is ubiquitous in the systems of interest but is a notoriously difficult fluid to model accurately using simple models of the sort that are tractable for use in the context of equation-of-state modelling. The provision of a good model of water underpins a large part of the work and is accomplished only as a result of further development of the theory upon which the equation of state is based, involving not only its statistical-mechanical foundation but also lengthy numerical procedures to isolate the most physically reasonable application of the theory. Bearing in mind its simplicity, the resulting model for water, within the context of the refined theory, provides for a remarkably good representation of the thermodynamic properties of water and forms a highlight of the thesis. The remaining part of the work is the development of a framework in which to treat the ionic components of reservoir fluids. Following the implementation of a standard method to treat electrolyte solutions, the main goal of the thesis is achieved with the modelling of the phase equilibria of CO2-brine systems, demonstrating that the proposed method is a suitable tool for the study of complex reservoir fluids containing carbon dioxide and brines.
Creating border crossing spaces for decolonizing critical literacy encounters in teacher preparation

description: Ultimately, this research study aimed to provide pathways for children of Color to engage in transformative literacy experiences that go well beyond developing basic, mechanical reading skills, to have access to learn in literacy classrooms that center opportunities for understanding and critiquing of their sociopolitical realities and colonial histories. In order to do that we need to understand the ways in which we can best prepare teachers to respond, include and engage with contemporary socio political, economic, and environmental realities in their literacy classrooms during increasingly difficult times in communities of Color. Guided by a critical case study methodology, this project sought out to answer two research questions: What discourses emerge from the deliberate cross-context collaboration of preservice teachers while learning about critical literacies and anti-colonial frameworks? And, how does a transnational collaboration, across teacher preparation programs in Texas and Puerto Rico, support preservice teachers’ understandings and applications of anti-colonial theories and methods? By bringing together critical literacy and de/anti-colonial theoretical frameworks, I learned that the most common discourses within the synchronous class discussions were the awakenings the preservice teachers experienced, how they participated in restrictions and ruptures through the possibilities of engaging in this work in elementary classrooms, and lastly how they held onto the double narrative argument. Regarding the collaboration in itself, my findings revealed the role of the collaboration, the teacher educators, and preservice teacher in the learning that occurred across contexts. Recommendations include a centering of voices of Color in the field of literacy teacher preparation, an openness to the ways in which preservice teachers will define colonialism in their own terms, and space to center emotion as a central to learning how to become critical de/anti-colonial literacy educators.

Collisional Particle In Cell Modelling Of The Propagation Of Fast Electrons In Solid Density Plasma
Creators: name: Lloyd, Rhys David
Publisher: name: Imperial College London
Year: 2011

description: This thesis looks at the effects that electron-ion Coulomb collisions have on fast electron transport in solid density plasma. The study of the fast electrons generated in ultra-high intensity laser-plasma interactions is important due to their envisioned use in the fast ignition approach to inertial confinement fusion. Collisions have been added to the particle-in-cell (PIC) code EPOCH in order to study the propagation of fast electron beams in various solid density targets. By using a collisional PIC model several of the assumptions used in previous studies are not required. The code solves the full Maxwell equations (including the displacement current), does not require assumptions of Ohm’s law and of Spitzer resistivity and does not require the background distributions to be Maxwellian. The thesis begins with summaries of the background theory and of the previous work performed in this area. The PIC method is then discussed and the way in which collisions were added to EPOCH is outlined. The results from several collisional PIC simulations with different target Z values are then discussed and com- pared to both collisionless PIC simulation results and hybrid simulation results. The effects of collisions have then been examined by looking into numerous aspects of the simulations that have been performed. Firstly, the generation of fields within the plasma and the subsequent filamentation of the fast electron beam are examined. The effects that the collisions have on the electron distributions within the plasma are then investigated with particular attention given to the divergence of the fast electrons, the energy and momentum distributions of the electrons and the background temperatures within the plasma. Finally, the results of the simulations are used to assess the accuracy of the Spitzer resistivity approximation that is used in hybrid codes.

Learning-based resource allocation in wireless networks
Creators: name: Blasco Moreno, Pol
Publisher: name: Imperial College London
Year: 2014

description: This thesis investigates learning-based resource allocation techniques for future wireless networks (FWNs). Motivated by recent technological developments, two types of FWNs are studied: energy harvesting (EH) wireless sensor networks (WSNs), and high-capacity cellular networks (HC-CNs) with caching capabilities. In an EH-WSN, each node is powered by a rechargeable battery and harvests energy from the environment. First, a multi-access throughput optimisation problem is studied, when the access point schedules EH sensor nodes without the knowledge of their battery states. A low-complexity policy is shown to be optimal in certain cases, and a scheduling algorithm, which takes into account the random processes governing the energy arrivals in the system, is proposed, and compared to an upper bound. Second, a point-to-point communication system with an EH transmitter is considered. Since the characteristics of the environment in which the sensor will be deployed are not known in advance, we assume no a priori knowledge of the random processes governing the system, and propose a learning theoretic optimisation for the system operation. The performance of the proposed algorithm is compared to that of two upper bounds, obtained by providing more information to the transmitter about the random processes governing the system. We then turn our attention to content-level selective offloading to an infostation terminal in an HC-CN. The infostation, which stores high data-rate content in its cache memory, allows cellular users in the vicinity to directly download the stored content through a broadband connection, reducing the latency and the load on the cellular network. The goal of the infostation cache controller is to store the most popular content such that the maximum amount of traffic is o oaded to the infostation. The optimal cache content management problem when content popularity is unknown is studied, and a number of algorithms to learn the content popularity pro le are proposed. The performances of these algorithms are compared to that of an informed upper bound, obtained when the content popularity pro le is known.

description: We present the results of X-ray spectroscopy of a flux-limited sample of seven middle-aged supernova remnants (SNRs) in the Large Magellanic Cloud (LMC) (N23, N49, N63A, DEM71, N132D, 0453-68.5, and N49B), using nonequilibrium ionization Sedov-phase SNR models. All the remnants were well described by the model, allowing us to derive accurate values for their ages, densities, initial explosion energies, and metal abundances. Four SNRs are fully consistent with the Sedov model and yield a mean value of the initial SN explosion energy of (1.1+/-0.5)x10^51 erg. We show that it is likely that the other three remnants exploded within preexisting cavities in the interstellar medium. The limits on high energy X-ray emission (>3 keV) that we present indicate that these SNRs do not contain very luminous pulsar-powered synchrotron nebulae. We find statistical evidence for enrichment by supernova ejecta in the sense that smaller remnants show a somewhat higher mean metallicity than the larger ones. For DEM71, the remnant of a SN Ia, the derived Fe abundance is about a factor of two larger than the other remnants in the sample. These things being said, however, the derived abundances are in general dominated by swept-up interstellar material and so we use the SNR sample to estimate the mean LMC gas-phase abundances. We find that the astrophysically common elements from O to Fe are less abundant than the solar values by factors of 2--4. Overall these results are consistent with previous ones based on optical and UV data, but do not show the anomalous overabundance of Mg and Si seen by others.

Optimising financial computation for reconfigurable hardware
Creators: name: Jin, Qiwei
Publisher: name: Imperial College London
Year: 2013

description: This thesis proposes novel methodologies for design, optimisation and generalisation of reconfigurable hardware based finance computation. The applications of the proposed methodologies to numerical methods which are commonly used in the finance industry, such as Monte Carlo and Finite Difference are studied in detail. These studies show reconfigurable hardware can effectively improve performance and energy efficiency in finance computation. There are three contributions. First, an application independent Monte Carlo framework for interest rate derivatives payoff evaluations based on the HeathJarrowMorton (HJM) mathematical Framework. By identifying three levels of functional specialisations in the model, the framework is able to retain good performance while supporting multiple applications. In addition, a process is proposed for the Monte Carlo framework to identify the optimal reduced precision data representation, in order to utilise hardware resource better and retain output numerical accuracy. The automatically generated Field-Programmable Gate Array (FPGA) implementations show significant speedup and energy saving over comparable Central Processing Unit (CPU) and Graphical Processing Unit (GPU). Second, a novel framework for accelerating option payoff evaluation based on finite difference method. The parallelism of the proposed architectures is exploited based on two levels of computational granularities. The implementations are generated based on a high level description. Significant speedup and energy savings are archived comparing our FPGA designs over both CPU and GPU designs. Third, a novel performance optimisation process based on dynamic reconfiguration for stencil computation. By optimally adjusting the underlying numerical procedure and making use of carefully chosen coefficients for constant multipliers, both the hardware resource consumption per kernel and the amount of computation needed per problem are reduced, and the numerical accuracy requirements are also met. Significant speedup is shown by comparing the optimised dynamic design with the unoptimised dynamic design and the original static design.

description: This thesis explores the potential roles of neutrophils in the host response to tuberculosis. First, a review of literature identifies the capacity of neutrophils to phagocytose and kill mycobacteria as well as their ability to influence the development of acquired immune responses. The effect of HIV infection on neutrophil function is also explored. Novel assays are presented to assess phagocytosis of mycobacteria (flow cytometry) and restriction of mycobacterial metabolism (bio-luminescence) by human neutrophils. Subsequently neutrophil function is investigated in HIV-infected antiretroviral-naïve patients and control participants from the same community. Results show that HIV-infected patients’ neutrophils restrict mycobacterial metabolism less effectively and undergo more rapid cell death than those of controls. The HIV-infected cohort is followed over 6 months of antiretroviral therapy; during this time all studied functions improve towards the levels of HIV-uninfected participants. In vitro studies on other modifiers of neutrophil antimycobacterial function are inconsistent but there is some evidence for an effect of zinc chloride in arresting neutrophil cell death. Augmentation of human blood with live or dead neutrophils before infection with M.tuberculosis significantly impacts on both mycobacterial control and supernatant cytokine responses. In particular, necrotic neutrophils facilitate more growth of M.tuberculosis and reduce Th1 cytokine responses while increasing IL-10 release. Further investigation into the influence of neutrophils on the development of antimycobacterial immune responses utilises a mouse model to study BCG vaccination. Macrophage Inflammatory Protein-2 (MIP-2)-mediated recruitment of additional neutrophils to the vaccination site significantly increases release of interferon-γ from restimulated splenocytes versus controls three weeks after vaccination, while 1A8 anti-Ly6G antibody-mediated neutrophil depletion pre-vaccination significantly decreases downstream interferon-γ release versus controls. Finally the prognostic significance of neutrophilia in active tuberculosis is investigated. This analysis on 1236 patients finds that neutrophilia, itself predicted by pulmonary disease and white ethnicity, is an independent risk factor for fatality.

description: Monte Carlo simulations are used to study the conformational properties of a folded semiflexible polymer confined to a long channel. We measure the variation in the conformational free energy with respect to the end-to-end distance of the polymer, and from these functions we extract the free energy of the hairpin fold, as well as the entropic force arising from interactions between the portions of the polymer that overlap along the channel. We consider the scaling of the free energies with respect to varying the persistence length of the polymer, as well as the channel dimensions for confinement in cylindrical, rectangular and triangular channels. We focus on polymer behaviour in both the classic Odijk and back folded Odijk regimes. We find the scaling of the entropic force to be close to that predicted from a scaling argument that treats interactions between deflection segments at the second virial level. In addition, the measured hairpin fold free energy is consistent with that obtained directly from a recent theoretical calculation for cylindrical channels. It is also consistent with values determined from measurements of the global persistence length of a polymer in the backfolded Odijk regime in recent simulation studies.

description: The purpose of the present paper is twofold. In the first part, we provide an algebraic characterization of several families of $ν= \frac{1}{2^n}$ $n\leq 5$ BPS states in M theory, at threshold and non-threshold, by an analysis of the BPS bound derived from the ${\cal N}=1$ D=11 SuperPoincaré algebra. We determine their BPS masses and their supersymmetry projection conditions, explicitly. In the second part, we develop an algebraic formulation to study the way BPS states transform under $GL(32,\bR)$ transformations, the group of automorphisms of the corresponding SuperPoincaré algebra. We prove that all $ν={1/2}$ non-threshold bound states are SO(32) related with $ν={1/2}$ BPS states at threshold having the same mass. We provide further examples of this phenomena for less supersymmetric $ν={1/4},{1/8}$ non-threshold bound states.

Financial institutions and asset prices
Creators: name: Ding, Lei
Publisher: name: Imperial College London
Year: 2014

description: This thesis analyses the role of financial institutions in determining asset prices both theoretically and empirically, and consists of three papers. Chapter 1 provides the motivation and a detailed summary of the three papers. Chapter 2 focuses on the hedge fund industry that has come to play a prominent role in today's financial markets due to its explosive growth. Fierce competition for funds generates relative performance objectives for managers. This paper studies how a hedge-fund manager's investment decision is affected by her tournament concern, incentive contract and liquidation threat. Chapter 3 examines the impact of both managerial capital and delegated capital on asset-market equilibrium by generalising the marginal investor to be a portfolio manager who is paid a relative performance fee. This chapter studies whether it is possible to stabilise financial markets by adopting a less centralized approach based on the idea of altering institutional incentives before a crisis rather than remedial actions after a crisis. Given that the model in Chapter 3 is an example of equity risk-capital models that fit the facts surrounding bank-based intermediaries, Chapter 4 investigates the characteristics of banks' balance sheets and also suggest that banks' balance sheets convey information on predicting subsequent asset-market variations. Chapter 5 concludes.

description: We examine whether a cosmologically significant distribution of dark galaxy group or cluster-sized objects can have an optical depth for multiple imaging of distant background sources which is comparable to that from known galaxies while at the same time producing angular splittings of the same order of magnitude. Our purpose is to explore whether such objects could realistically account for some of the observed lenses. Modeling such systems as isothermal spheres with core radii, and assuming a Schechter-type distribution function, we find that independent of the cosmology (open, flat matter dominated, or flat cosmological constant dominated) an allowed parameter range exists which is comparable in velocity dispersion to that for known compact groups of galaxies, although the preferred core radii are somewhat smaller than that normally assumed for compact groups. Dark cluster-sized objects, on the other hand, cannot reproduce the observed lensing characteristics. If the one known Dark cluster were a good representative of such a distribution, most such objects would not produce multiple images. We also present a result for the angular splitting due to an isothermal sphere lens with non-zero core radius, extending earlier work of Hinshaw and Krauss (1987). Our results are expressed as contour plots for fixed lensing probabilities, and angular splittings.

description: Higher-order networks are widely used to describe complex systems in which interactions can involve more than two entities at once. In this paper, we focus on inclusion within higher-order networks, referring to situations where specific entities participate in an interaction, and subsets of those entities also interact with each other. Traditional modeling approaches to higher-order networks tend to either not consider inclusion at all (e.g., hypergraph models) or explicitly assume perfect and complete inclusion (e.g., simplicial complex models). To allow for a more nuanced assessment of inclusion in higher-order networks, we introduce the concept of "simpliciality" and several corresponding measures. Contrary to current modeling practice, we show that empirically observed systems rarely lie at either end of the simpliciality spectrum. In addition, we show that generative models fitted to these datasets struggle to capture their inclusion structure. These findings suggest new modeling directions for the field of higher-order network science.

description: The $e^-$-$e^+$ bound state spectrum of QED3 is investigated in the quenched ladder approximation to the homogeneous Bethe-Salpeter equation with fermion propagators from a rainbow approximation Schwinger-Dyson equation. A detailed analysis of the analytic structure of the fermion propagator is performed so as to test the appropriateness of the methods employed. The large fermion mass limit of the Bethe-Salpeter equation is also considered, including a derivation of the Schrödinger equation, and comparisons made with existing non-relativistic calculations.

The role of liver receptor homologue-1 (LRH-1) in breast cancer
Creators: name: Lai, Chun Fui
Publisher: name: Imperial College London

description: Estrogens play a critical role in the development and progression of breast cancer. The biological functions of estrogen are mainly mediated by estrogen receptors (ER), which act by regulating gene expression in breast cancer cells. Previously our laboratory identified liver receptor homologue-1 (LRH-1), a member of the nuclear receptor superfamily of transcription factors to which ER also belongs, as an estrogen-responsive gene. Subsequent work showed that LRH-1 is important in mediating the growth of breast cancer cells. Herein, I show that LRH-1 in turn regulates the expression of ERα, providing a positive feedback loop, which may act to promote stable co-expression of ERα and LRH-1 in breast cancer cells. To better define the mechanisms of LRH-1 action in breast cancer cells, gene expression microarray analysis was performed following RNA interference mediated LRH-1 knockdown. Microarray analysis demonstrated that LRH-1 regulates the expression of many estrogen-responsive genes. ChIP-seq analysis, carried out to identify global LRH-1 binding sites, showed that LRH-1 is recruited to a substantial proportion of estrogen-regulated genes, frequently binding to ERα binding sites, suggesting LRH-1 directly regulates a subset of ERα-target genes in breast cancer cells. Analysis of select binding sites confirmed the direct LRH-1 regulation of ERα target genes through LRH-1 binding to estrogen response elements (ERE), as exemplified by the TFF1/pS2 gene. Moreover, LRH-1 was shown to stimulate the recruitment of ERα to the ERE in the shared/common target genes, suggesting a co-operative function between LRH-1 and ERα. Collectively, these findings show that LRH-1 is a key mediator of the estrogen response in breast cancer cells and raises the possibility of targeting LRH-1 for the treatment of breast cancer. Towards this end, I also describe the identification of novel LRH-1 antagonists that inhibit breast cancer cell growth. Development of these compounds will offer investigational tools for validating the importance of LRH-1 in breast cancer, towards a therapeutic strategy in breast cancer treatment.
