description: We report on the coexistence of both normal and topological insulating phases in InAs/GaSb bilayer quantum well induced by the built-in electric field tuned optically and electrically. The emergence of topological and normal insulating phases is assessed based on the evolution of the charge carrier densities, the resistivity dependence of the gap via in-plane magnetic fields and the thermal activation of carriers. For the Hall bar device tuned optically, we observe the fingerprints associated with the presence of only the topological insulating phase. For another Hall bar processed identically but with an additional top gate, the coexistence of normal and topological insulating phases is found by electrical tuning. Our finding paves the way for utilizing a new electro-optical tuning scheme to manipulate InAs/GaSb bilayer quantum wells to obtain trivial-topological insulating interfaces in the bulk rather than at the physical edge of the device.

Demazure-Lusztig Operators and Metaplectic Whittaker Functions on Covers of the General Linear Group
Creators: Puskas, Anna
Publisher: name: Columbia University
Year: 2014
Subjects: subject: Mathematics
subject: FOS: Mathematics

description: There are two different approaches to constructing Whittaker functions of metaplectic groups over non-archimedean local fields. One approach, due to Chinta and Offen for the general linear group and to McNamara in general, represents the spherical Whittaker function in terms of a sum over a Weyl group. The second approach, by Brubaker, Bump and Friedberg and separately by McNamara, expresses it as a sum over a highest weight crystal.
      This work builds a direct, combinatorial connection between the two approaches. This is done by exploring both in terms of Demazure and Demazure-Lusztig operators associated to the Weyl group of an irreducible root system. The relevance of Demazure and Demazure-Lusztig operators is indicated by results in the non-metaplectic setting: the Demazure character formula, Tokuyama's theorem and the work of Brubaker, Bump and Licata in describing Iwahori-Whittaker functions.
      The first set of results is joint work with Gautam Chinta and Paul E. Gunnells. We define metaplectic Demazure and Demazure-Lusztig operators for a root system of any type. We prove that they satisfy the same Braid relations and quadratic relations as their nonmetaplectic analogues. Then we prove two formulas for the long word in the Weyl group. One is a metaplectic generalization of Demazure's character formula, and the other connects the same expression to Demazure-Lusztig operators. Comparing the two results to McNamara's construction of metaplectic Whittaker functions results in a formula for the Whittaker functions in the spirit of the Demazure character formula.
      The second set of results relates to Tokuyama's theorem about the crystal description of type A characters. We prove a metaplectic generalization of this theorem. This establishes a combinatorial link between the two approaches to constructing Whittaker functions for metaplectic covers of any degree. The metaplectic version of Tokuyama's theorem is proved as a special case of a stronger result: a crystal description of polynomials produced by sums of Demazure-Lusztig operators acting on a monomial. These results make use of the Demazure and Demazure-Lusztig formulas above, and the branching structure of highest weight crystals of type A. The polynomials produced by sums of Demazure-Lusztig operators acting on a monomial are related to Iwahori fixed Whittaker functions in the nonmetaplectic setting.

description: Heckman and Opdam introduced a non-symmetric analogue of Jack polynomials using Cherednik operators. In this paper, we derive a simple recursion formula for these polynomials and formulas relating the symmetric Jack polynomials with the non-symmetric ones. These formulas are then implemented by a closed expression of symmetric and non-symmetric Jack polynomials in terms of certain tableaux. The main application is a proof of a conjecture of Macdonald stating certain integrality and positivity properties of Jack polynomials.

description: Clean hydrogen production through efficient and cost-effective electrochemical water splitting is highly promising to meeting future global energy demands. The design of Earth-abundant materials with both high activity for hydrogen evolution reaction (HER) and electrochemical stability in both acidic and alkaline environments summarize the outcomes needed for practical applications. Here, we report a non-noble 3d metal Cl-chemical doping of liquid phase exfoliated single/few-layer flakes of MoSe2 for creating MoSe2 nanoflakes/3d metal oxide-hydr(oxy)oxide hybrid HER-catalysts. We propose that the electron-transfer from MoSe2 nanoflakes to metal cations and the chlorine complexation-induced both neutralization, as well as the in situ formation of metal oxide-hydr(oxy)oxides on MoSe2 nanoflake's surface, tailor the proton affinity of the derived catalysts, increasing the number and HER-kinetic of their active sites in both acidic and alkaline electrolytes. The electrochemical coupling between the doped-MoSe2 nanoflakes/metal oxide-hydr(oxy)oxide hybrids and single-walled carbon nanotubes heterostructures further accelerates the HER process. Lastly, monolithic stacking of multiple heterostructures is reported as a facile electrode assembly strategy to achieve overpotential for a cathodic current density of 10mAcm-2 of 0.081V and 0.064V in 0.5M H2SO4 and 1M KOH, respectively. This opens up new opportunities to address the current density vs. overpotential requirements targeted in pH-universal H2 production.

description: Decay-time-dependent $CP$-violation effects in transitions of neutral $B$ mesons to $CP$-eigenstates can be visualised by oscillations in the asymmetry, as a function of decay time, between decay yields from mesons tagged as initially having $\overline{B}$ or $B$ flavour. Such images, for example for $B^0 \to J/ψK^0_{\rm S}$ decays where the magnitude of the oscillation is proportional to $\sin(2β)$ with $β$ being an angle of the Cabibbo--Kobayashi--Maskawa Unitarity Triangle, provide a straightforward illustration of the underlying physics. Until now there has been no comparable method to provide visualisation for the case of decays to multibody final states that are not $CP$-eigenstates, where interference between $CP$-even and -odd amplitudes provides additional physics sensitivity. A method is proposed to weight the data so that the terms of interest can be projected out and used to obtain asymmetries that visualise the relevant effects. Application of the weighting to $B^0_s$ decays, where effects due to non-zero width difference are not negligible, provides a novel method to observe $CP$ violation in interference between mixing and decay without tagging the production flavour.

description: This dissertation concerns the history of land politics in South Africa and, equally, land as a vehicle for understanding the transition from apartheid to the post-apartheid order. In 2004, after a decade in power, the ANC government’s failure to carry out widespread land reform began to test the country’s democratic possibilities. In the lead up to that year’s national election, social movements urged landless people to boycott the polls and occupy land instead as part of a “No Land! No Vote!” campaign. With this clash as its entry point for analysis, this dissertation examines historical factors that have shaped South Africa’s neoliberal democracy and prospects for redistribution. It offers insights into some of the most significant questions facing the country: What is the historical relationship between land dispossession, citizenship, and politics in South Africa? And why, well into the Mbeki years, was the country unable, or unwilling, to reckon with it?
      	Broad in scope, this dissertation examines a number of institutions that shaped the politics of land, economic development, and citizenship in South Africa over the last century. It is particularly focused on period of the 1940s-2004, encompassing the apartheid era and the first ten years of democracy. I begin by recasting the history of apartheid pass laws in the mid-twentieth century, widening the scope beyond their role in containing labor mobility and controlling access to cities. I show how vagrancy laws were one piece of a continuum that stretched through jails and prisons to rural plantations, supplying labor to farms and subsidizing agricultural development. Later chapters examine how, beginning in the 1970s, the World Bank and other international institutions helped shape the contours of land and housing policies and the relationship between states and citizens. My research also shows how, during the apartheid transition and through the Mandela and Mbeki administrations, private prisons and harsh criminal justice reforms became integral parts of neoliberal economic development. This dissertation weaves together the history that has shaped South Africa’s ‘dispossessed democracy’ and concludes with a discussion of the implications for social movements and political change.

description: Perhaps because of the elegance of the central limit theorem, it is often assumed that distributions in nature will approach singly-peaked, unimodal shapes reminiscent of the Gaussian normal distribution. However, many systems behave differently, with variables following apparently bimodal or multimodal distributions. Here we argue that multimodality may emerge naturally as a result of repulsive or inhibitory coupling dynamics, and we show rigorously how it emerges for a broad class of coupling functions in variants of the paradigmatic Kuramoto model.

description: In this paper, we introduce a new family of symmetric polynomials which depends on a parameter r. They are defined by specifying certain of their zeros. For the parameter values 1/2, 1, and 2 they have an interpretation in terms of Capelli identities. First, we give explicit formulas in some special cases. Then we show that the polynomials can also be defined in terms of difference equations. As a corollary we obtain that their top homogeneous part is a Jack polynomial. This is used to give a new proof of the Pieri formula for Jack polynomials.

description: Among astrophysical sources in the Advanced LIGO and Advanced Virgo detectors' frequency band are rotating non-axisymmetric neutron stars emitting long-lasting, almost-monochromatic gravitational waves. Searches for these continuous gravitational-wave signals are usually performed in long stretches of data in a matched-filter framework e.g., the F-statistic method. In an all-sky search for a priori unknown sources, large number of templates is matched against the data using a pre-defined grid of variables (the gravitational-wave frequency and its derivatives, sky coordinates), subsequently producing a collection of candidate signals, corresponding to the grid points at which the signal reaches a pre-defined signal-to-noise threshold. An astrophysical signature of the signal is encoded in the multi-dimensional vector distribution of the candidate signals. In the first work of this kind, we apply a deep learning approach to classify the distributions. We consider three basic classes: Gaussian noise, astrophysical gravitational-wave signal, and a constant-frequency detector artifact ("stationary line"), the two latter injected into the Gaussian noise. 1D and 2D versions of a convolutional neural network classifier are implemented, trained and tested on a broad range of signal frequencies. We demonstrate that these implementations correctly classify the instances of data at various signal-to-noise ratios and signal frequencies, while also showing concept generalization i.e., satisfactory performance at previously unseen frequencies. In addition we discuss the deficiencies, computational requirements and possible applications of these implementations.

Generation of many-particle entanglement in an ion trap by adiabatic ground-state transitions

Year: 2002
Subjects: subject: Quantum Physics (quant-ph)

description: We discuss the creation of many-particle entanglement in an ion trap where all ions are simultaneously coupled to bichromatic laser fields. It is shown that in a time-averaged, coarse-grained picture the system can be mapped onto a spin ensemble with controllable collective interactions. An adiabatic change of laser parameters allows a transfer from separable to entangled eigenstates of the many-particle Hamiltonian. Of particular interest is a transition in the ground state which in some cases corresponds to a quantum phase transition. The influence of decoherence mechanisms can be substantially reduced if at all times a sufficiently large energy gap between the ground state and the first excited state is maintained.

description: This paper continues the approach of Kostenko \& Thompson to calculating quantum electrodynamic processes in the ultrastrong magnetic field near some neutron stars, such as magnetars or merging binary neutron stars. Here we consider electron-positron scattering, the Coulomb scattering of electrons and positrons off ions, and relativistic $e^\pm$-ion bremsstrahlung. The evaluation of differential and total cross sections simplifies considerably when the magnetic field lies in the range $10^3B_{\rm Q} \gg B \gg B_{\rm Q}$, where $B_{\rm Q} \equiv m^2/e = 4.4\times 10^{13}$ G. Then, relativistic motion of $e^\pm$ is possible even when restricted to the lowest Landau state. Accurate results for differential and total cross sections are obtained by truncating the sum over intermediate-state Landau levels and otherwise disregarding terms inversely proportional to the magnetic field, which are complicated enough to have inhibited previous attempts to calculate magnetic electron-positron scattering and relativistic bremsstrahlung. A quantitative account is made of the effects of Debye screening.

Redistribution of energy at low-to-modest $p_T$ has been elusive to measure because of large anisotropic backgrounds. We report a data-driven method for background evaluation and subtraction, exploiting the away-side pseudorapidity gaps, to measure the jetlike correlation shape in Au+Au collisions at $\sqrt{s_{_\mathrm{NN}}}=200$ GeV with the STAR experiment. The correlation shapes, for trigger particle $p_T>3$ GeV/$c$ and various associated particle $p_T$ ranges within $0.5

description: The dielectric properties of thin films are of paramount important in a variety of technological applications, and of fundamental importance for solid state research. In spite of this, there is currently no theoretical understanding of the dependence of the dielectric permittivity on the thickness of thin films. We develop a confinement model within the Lorentz-field framework for the microscopic Langevin-equation description of dielectric response in terms of the atomic-scale vibrational modes of the solid. Based on this, we derive analytical expressions for the dielectric permittivity as a function of thin film thickness, in excellent agreement with experimental data of Barium-Strontium-Titanate (BST) thin films of different stoichiometry. The theory shows that the decrease of dielectric permittivity with decreasing thickness is directly caused by the restriction in $k$-space of the available eigenmodes for field-induced alignment of ions and charged groups.

description: Accurately identifying who in the population is the poorest of the poor is critical for developing efficient and effective poverty reduction strategies. A key part of this task is to compare household welfare across households of different sizes, compositions and sub-national locations. Yet the typical equivalence scales used in this process by most policymakers impose harsh and unrealistic assumptions on household behaviour and the extent to which households of different sizes realise economies of scale in consumption (CSE). These assumptions include the notion that household tastes are unrelated to income (homothetic preferences) and no substantial differences exist in the extent to which CSE can be realised across households located in different sub-national regions, time periods and gender compositions. This thesis focuses mainly on analysing the CSE associated with food consumption, labelled as FCSE, since expenditure on food represents the major share of household expenditure for poor households. The main objective of this thesis is to investigate how household characteristics and their behavioural choices affect the ability of these households to achieve FCSE, and thereby their poverty status, using Sri Lanka as a case study. In doing so, the relationships between FCSE and a number of household socio-economic and demographic characteristics and household behavioural choices are investigated. The characteristics considered comprise household size, location, income, and gender of the head of household; the behavioural choices considered comprise the decision to consume home-grown food, and the decision to adopt domestic technology to aid food preparation and consumption.

description: Women are underrepresented in many areas of journalistic newsrooms. In this paper, we examine if this established effect continues in the new forms of journalistic communication, Social Media Networks. We used mentions, retweets, and hashtags as journalistic amplification and legitimation measures. Furthermore, we compared two groups of journalists in different stages of development: political and data journalists in Germany in 2021. Our results show that journalists regarded as women tend to favor their other women in mentions and retweets on Twitter, compared to men. While both professions are dominated by many men and a high share of men-authored tweets, women are mentioning and retweeting other women to a more extensive degree than their male colleagues. Women data journalists also leveraged different sources than men. In addition, we have found data journalists to be more inclusive towards non-member sources in their network compared to political journalists.

description: Calibration techniques were investigated on how to best optimize a 149 parameter, distributed hydrological model of the Lake of the Woods – Rainy Lake (LOWRL) watershed. Single objective calibrations based only on streamflow, only on reservoir inflows or average performance of both observation types, optimized using the Dynamically Dimensioned Search (DDS) algorithm, were compared with a multi-objective optimization approach with both observation types using the Pareto Archived DDS (PADDS) algorithm. Results from synthetic calibration tests against a known solution showed that PADDS was able to repeatedly find solutions with streamflow and reservoir inflow Nash-Sutcliffe coefficients of more than 0.95 and 0.99 using 2000 and 8000 model evaluations, respectively, demonstrating the effectiveness of PADDS on a limited calibration budget. When the LOWRL model was calibrated to actual observations with PADDS using 2000 evaluations, the algorithm repeatedly returned solutions with validation period streamflow and reservoir inflow Nash-Sutcliffe coefficients of approximately 0.71 and 0.87, respectively. Results demonstrate the capabilities of PADDS to reasonably calibrate a large dimensional hydrologic model on a restricted budget of 2000 model evaluations and highlight the importance of calibrating to both reservoir inflows and streamflows simultaneously. Considering the comparative results under multiple calibration trials, the multi-objective formulation solved by PADDS is shown to generate equivalent quality results as a weighted single objective approach solved by DDS (averaging reservoir inflow and streamflow calibration objectives).

È in uscita su Astronomy & Astrophysics il primo modello che riesce a riprodurre le proprietà di un resto di supernova di tipo “mixed-morphology”. Lo studio, guidato da Sabina Ustamujic dell’Inaf di Palermo, ha permesso di vincolare l’età del resto di supernova Ic 443, la massa del materiale espulso dalla supernova e l’energia dell’esplosione – tutti parametri importanti per vincolare i modelli di supernova
Resurgence in the Transition Region: The Incomplete Gamma Function

description: We study the resurgence properties of the coefficients $C_n(τ)$ appearing in the asymptotic expansion of the incomplete gamma function within the transition region. Our findings reveal that the asymptotic behaviour of $C_n(τ)$ as $n\to +\infty$ depends on the parity of $n$. Both $C_{2n-1}(τ)$ and $C_{2n}(τ)$ exhibit behaviours characterised by a leading term accompanied by an inverse factorial series, where the coefficients are once again $C_{2k-1}(τ)$ and $C_{2k}(τ)$, respectively. Our derivation employs elementary tools and relies on the known resurgence properties of the asymptotic expansion of the gamma function and the uniform asymptotic expansion of the incomplete gamma function. To the best of our knowledge, prior to this paper, there has been no investigation in the existing literature regarding the resurgence properties of asymptotic expansions in transition regions.

description: In this article we consider a generalization of manifolds and orbifolds which we call quasifolds; quasifolds of dimension k are locally isomorphic to the quotient of R^k by the action of a discrete group - tipically they are not Hausdorff topological spaces. The analogue of a torus in this geometry is a quasitorus. We define Hamiltonian actions of quasitori on symplectic quasifolds and we show that any simple convex polytope, rational or not, is the image of the moment mapping for a family of effective Hamiltonian actions on symplectic quasifolds having twice the dimension of the corresponding quasitorus.

description: Present work describes the fabrication of polypropylene (PP) and expanded polytetrafluoroethylene (ePTFE) air filters with antibacterial properties and more stability against washing cycles. Silver nanowires (AgNWs) were used as antibacterial agents on the filters. Deposition of AgNWs directly on the surfaces of the PP and ePTFE resulted in the preparation of the products that their antibacterial properties were significantly reduced after a few washing cycles. In order to immobilize the AgNWs on the surface of highly hydrophobic substrates such as ePTFE and PP, sodium naphthalenide was used to modify the surfaces of the PP and ePTFE fibers. The presence of sodium naphthalenide reduces the hydrophobic properties of the fibers and therefore it can increase the bonding of AgNWs to the surface. The results of the antibacterial test showed that these modified membranes have a higher durability compared to those modified without sodium naphthalenide interfacial layer.

description: The effectiveness of an IR system is gauged not just by its ability to retrieve relevant results but also by how it presents these results to users; an engaging presentation often correlates with increased user satisfaction. While existing research has delved into the link between user satisfaction, IR performance metrics, and presentation, these aspects have typically been investigated in isolation. Our research aims to bridge this gap by examining the relationship between query performance, presentation and user satisfaction. For our analysis, we conducted a between-subjects experiment comparing the effectiveness of various result card layouts for an ad-hoc news search interface. Drawing data from the TREC WaPo 2018 collection, we centered our study on four specific topics. Within each of these topics, we assessed six distinct queries with varying nDCG values. Our study involved 164 participants who were exposed to one of five distinct layouts containing result cards, such as "title'', "title+image'', or "title+image+summary''. Our findings indicate that while nDCG is a strong predictor of user satisfaction at the query level, there exists no linear relationship between the performance of the query, presentation of results and user satisfaction. However, when considering the total gain on the initial result page, we observed that presentation does play a significant role in user satisfaction (at the query level) for certain layouts with result cards such as, title+image or title+image+summary. Our results also suggest that the layout differences have complex and multifaceted impacts on satisfaction. We demonstrate the capacity to equalize user satisfaction levels between queries of varying performance by changing how results are presented. This emphasizes the necessity to harmonize both performance and presentation in IR systems, considering users' diverse preferences.
