Collective effects enhanced multi-qubit information engines

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

description: We study a quantum information engine (QIE) modeled by a multi-qubit working medium (WM) collectively coupled to a single thermal bath. We show that one can harness the collective effects to significantly enhance the performance of the QIE, as compared to equivalent engines lacking collective effects. We use one bit of information about the WM magnetization to extract work from the thermal bath. We analyze the work output, noise-to-signal ratio and thermodynamic uncertainty relation, and contrast these performance metrics of a collective QIE with that of an engine whose WM qubits are coupled independently to a thermal bath. We show that in the limit of high temperatures of the thermal bath, a collective QIE always outperforms its independent counterpart. In contrast to quantum heat engines, where collective enhancement in specific heat plays a direct role in improving the performance of the engines, here the collective advantage stems from higher occupation probabilities for the higher energy levels of the positive magnetization states, as compared to the independent case.

description: Controllability of longer-term interest rates requires that the persis- tence of their deviations from the central bank's policy rate (i.e. the policy spreads) remains sufficiently low. This paper applies fractional integration techniques to assess the persistence of policy spreads of euro area money market rates along the yield curve. Independently from anticipated policy rate changes, there is strong evidence for all maturities that policy spreads exhibit long memory. We show that recent changes in the operational framework and the communication strategy of the European Central Bank have significantly decreased the persistence of euro area policy spreads and, thus, have enhanced the central bank's in uence on longer-term money market rates.
title: Coping Skills, Social Support, and Quality of Life Among Puerto Rican Women Undergoing Drug and/or Alcohol Treatment
Creators: name: Vázquez-Colón, Cheryl A.
Publisher: name: Western Washington University
Year: 2016

description:
The aim of this study is to examine how Puerto Rican women undergoing illicit drug and/or alcohol treatment cope with stress and how specific coping strategies may relate to greater well-being. Thirty-five participants were recruited from six different treatment centers in Puerto Rico. Participants described two stressful events, one with internal control and other with low internal control. Problem and emotion-focused coping strategies were measured with the Spanish version of the Brief COPE inventory. Quality of life was measured with the Spanish version of the WHOQOL-BREF, both measures have good internal reliability and have been used among Hispanic samples. Moreover, social support was measured using the Spanish version of the MOS Social Support Scale to test its effect over coping strategies and quality of life. We expect that when there is low control, emotion-focused will be positively related with quality of life insofar that emotion-focused coping will be positively associated with emotional social support which will then predict quality of life. Additionally, when there is high control, problem-focused coping will be positively related with quality of life insofar that problem-focused coping will be positively associated with instrumental social support which will then predict quality of life. This was one of the first studies that examined coping strategies and quality of life among Puerto Rican women undergoing illicit drug and/or alcohol recovery. Understanding how women cope and its relation with quality of life might provide a better insight to treatment development and long-term recovery

description: In this paper, we consider the problem of quantum measurement of neutrino velocity. We show, that the well known neutrino flavor oscillations are always accompanied by the oscillations of neutrino velocity. In particular, the velocity of a freely moving neutrino is demonstrated to periodically exceed the speed of light. Unfortunately, the superluminal effect turns out to be too small to be experimentally detected. It is also shown that neutrino velocity significantly depends on the energy, size and shape of the neutrino wave packet. Owing to the big experimental error of the recent experiments, these dependences remained unnoticeable. Finally, we have shown that the recent claims that superluminal neutrinos should loose energy during their flight is not true. Instead, our formula suggests the approximate conservation of energy along neutrino trajectory. All these results have been obtained without violation of special theory of relativity.

title: Toward Accurate and Efficient Computational Screening of the Electronic Structure and Band Gaps of Semiconductors
Creators: name: Grabill, Linda
Publisher: name: Western Washington University
Year: 2016

description:
With increasing population, growing energy demands, and environmental concerns the search for greener energy resources has intensified in recent decades. For example, in the ongoing effort to harness solar energy, researchers have worked to identify and optimize the efficiency of semiconductors beyond traditional silicon photovoltaic materials.

In the development of new materials, synthetic chemists and materials scientists often look to computational chemistry to guide and understand experiments. In the case of semiconductors for solar energy conversion, this includes calculations of electronic band structure and band gap. The most precise computational approaches, such as density functional theory (DFT) are both time consuming and demanding of computer resources. Less computationally demanding methods, such as the semi-empirical extended Hückel (eH) method, are generally seen as less quantitatively predictive. In this work, we show that the eH electronic band structures of three prototypical semiconductors -- CdSe, SrTiO3, and TiO2 -- can be brought into close quantitative agreement with DFT when the eH elemental parameters are systematically calibrated. We show that it is possible to simultaneously calibrate parameters for two compounds, suggesting that our approach can in the future be used to quickly and transferably screen and predict the electronic properties of a wide range of novel materials.

The hybrid dynamical and statistical approaches which have been developed previously are able to describe the experimental data reasonably. We discuss the intriguing difference between the yields of normal nuclei and hypernuclei which may be related to the properties of hypermatter at subnuclear densities. Most importantly new (hyper-)nuclei could be detected via particle correlations, and such measurements are relevant to pin down the production mechanism.

Redshift-space distortions from the cross-correlation of photometric populations

description: Several papers have recently highlighted the possibility of measuring redshift space distortions from angular auto-correlations of galaxies in photometric redshift bins. In this work we extend this idea to include as observables the cross-correlations between redshift bins, as an additional way of measuring radial information. We show that this extra information allows to reduce the recovered error in the growth rate index γby a factor of ~2. Although the final error in γdepends on the bias and the mean photometric accuracy of the galaxy sample, the improvement from adding cross-correlations is robust in different settings. Another factor of 2-3 improvement in the determination of γcan be achieved by considering two galaxy populations over the same photometric sky area but with different biases. This additional gain is shown to be much larger than the one from the same populations when observed over different areas of the sky (with twice the combined area). The total improvement of ~5 implies that a photometric survey such as the Dark Energy Survey should be able to recover γat the 5-10% from the angular clustering in linear scales of two different tracers. It can also constrain the evolution of f(z)xσ_8(z) in few bins beyond z~0.8-0.9 at the 10-15% level per-bin, compatible with recent constrains from lower-z spectroscopic surveys. We also show how further improvement can be achieved by reducing the photometric redshift error.

Redistribution and insurance in the German welfare state

Year: 2011
Subjects: subject: Long-term income inequality
subject: Income redistribution
subject: Social security
subject: 300 Sozialwissenschaften::330 Wirtschaft::336 Öffentliche Finanzen

description: Welfare states redistribute both between individuals (inter-individual redistribution) reducing annual, cross-sectional inequality and over the lifecycle of an individual (intra-individual redistribution) insuring individuals against income risks in the long-term. But studies measuring redistribution often focus on a one-year period and the second aspect is neglected. To quantify both inter- and intra-individual redistribution in Germany this study uses SOEP data from 1984 to 2009 to construct long-term incomes over a 20-year period. Results show that annual, cross-sectional inequality is higher than inequality in the long-run, but the effect of redistribution is also larger annually than in the long-term. Depending on age the distributional focus of the German welfare state differs. When persons are young, state intervention reduces income differences between individuals mainly through the progressive tax system. Getting older and reaching retirement age income-smoothing redistribution via social security pensions becomes central.

description: Die Open-Access-Transformation ist im Bibliotheksalltag insofern angekommen, als dass man sich jetzt mit der Abwicklung von Open-Access-Rechnungen, der Unterstützung von Wissenschaftler*innen beim Veröffentlichungsprozess, dem Open-Access-Berichtswesen, aber auch mit falsch zugeordneten Publikationen oder Fehlern im Verlagsworkflow beschäftigt. Diese Aufgaben in der Praxis ergeben sich aus den abgeschlossenen Transformationsverträgen, den eingerichteten Open-Access-Fonds und weiteren lokal aufgebauten Publikationsservices. In diesem Vortrag wollen wir einen Schritt zurückgehen und einige der dahinterstehenden Ziele genauer beleuchten sowie von den derzeit beschrittenen Wegen abgrenzen. Diese kritische Reflexion soll sich insbesondere um die folgende Frage drehen: Fokussieren sich unsere aktuellen Anstrengungen auf die richtigen Aspekte und dienen den gewünschten Zielen der Open-Access-Transformation?

Der Vortrag wird sich auf drei Aspekte konzentrieren: 1) Das vielfach propagierte Informationsbudget sehen wir mehr als einen möglichen Weg und nicht als das Ziel selbst an. Insbesondere die zentrale Steuerung von Publikationsmitteln sehen wir in Mannheim kritisch und nicht als notwendig um eine Kostenübersicht und -transparenz in dem Bereich zu erreichen. 2) Die antiquierten und nicht nachhaltigen Publikationskosten wie hybride OA-Gebühren, Color Charges, Gebühren für Überlänge etc. werden meist dezentral bezahlt. Eine Analyse unserer gesamtuniversitären Publikationskosten zeigt, dass ein nicht unerheblicher Teil davon auch aus Drittmitteln von Forschungsförderer finanziert wird. Es sollte aber das gemeinsame Ziel von Seiten der Wissenschaft sein, darauf hinzuwirken, dass diese Gebühren nicht mehr erhoben bzw. bezahlt werden. 3) Zudem möchte ich artikelbasierte Abrechnungsverfahren auf den Prüfstand stellen und fragen, inwiefern diese mit effektiven Kostenrechnungen korrelieren und erstrebenswert sind. All diese Betrachtungen sollen zur Reflexion und weiteren Diskussion anregen.
Emission-line stars discovered in the UKST H-alpha survey of the Large Magellanic Cloud; Part 1: Hot stars

description: We present new, accurate positions, spectral classifications, radial and rotational velocities, H-alpha fluxes, equivalent widths and B,V,I,R magnitudes for 579 hot emission-line stars (classes B0 - F9) in the Large Magellanic Cloud which include 469 new discoveries. Candidate emission line stars were discovered using a deep, high resolution H-alpha map of the central 25 deg2 of the LMC obtained by median stacking a dozen 2 hour H-alpha exposures taken with the UK Schmidt Telescope. Spectroscopic follow-up observations on the AAT, UKST, VLT, the SAAO 1.9m and the MSSSO 2.3m telescope have established the identity of these faint sources down to magnitude R~23 for H-alpha (4.5 x 10^-17 ergs cm^2 s^-1 Ang). Confirmed emission-line stars have been assigned an underlying spectral classification through cross-correlation against 131 absorption line template spectra covering the range O1 to F8. We confirm 111 previously identified emission line stars and 64 previously known variable stars with spectral types hotter than F8. The majority of hot stars identified (518 stars or 89%) are class B. Of all the hot emission-line stars in classes B-F, 130 or 22% are type B[e], characterised by the presence of forbidden emission lines such as [SII], [NII] and [OII]. We report on the physical location of these stars with reference to possible contamination from ambient HII emission. Along with flux calibration of the H-alpha emission we provide the first H-alpha luminosity function for selected sub-samples after correction for any possible nebula or ambient contamination. We find a moderate correlation between the intensity of H-alpha emission and the V magnitude of the central star based on SuperCOSMOS magnitudes and OGLE-II photometry where possible. Cool stars from classes G-S, with and without strong H-alpha emission, will be the focus of part 2 in this series.

description: We extract transverse momentum dependent feed-down fractions for bottomonium production using a data-driven approach. We use data published by the ATLAS, CMS, and LHCb Collaborations for sqrt(s) = 7 TeV proton-proton collisions. Based on this collected data, we produce fits to the differential cross sections for the production of both S- and P-wave bottomonium states. Combining these fits with branching ratios for excited state decays from the Particle Data Group, we compute the feed-down fractions for both the Upsilon(1S) and Upsilon(2S) as a function of transverse momentum. Our results indicate a strong dependence on transverse momentum, which is consistent with prior extractions of the feed-down fractions. When evaluated at the average momentum of the states, we find that approximately 75% of Upsilon(1S) and Upsilon(2S) states are produced directly. Our results for the transverse momentum dependent feed-down fractions are provided in tabulated form so that they can be used by other research groups.

description: Given the significant advancement in Bayesian inference of nuclear Equation of State (EOS) from gravitational wave and X-ray observations of neutron stars (NSs), especially since GW170817, is there a data-driven and robust empirical formula for the radius $R_{1.4}$ of canonical NSs in terms of the characteristic EOS parameters (features)? What is the single most important but currently poorly known EOS parameter for determining the $R_{1.4}$? We study these questions by extending the traditional Bayesian analysis which normally ends at presenting the marginalized posterior probability distribution functions (PDFs) of individual EOS parameters and their correlations (or sometimes only the Pearson correlation coefficients which are only reliably useful when the variables are linearly correlated while they are actually often not). Using three regression model-building methodologies: bidirectional step-wise feature selection, Least Absolute Shrinkage Selection Operator (LASSO) regression, and neural network regression on a large set of posterior EOSs and the corresponding $R_{1.4}$ values inferred from earlier comprehensive Bayesian analyses of NS observational data, we systematically and rigorously develop the most probable $R_{1.4}$ formulas with varying statistical accuracy and technical complexity. The most important EOS parameters for determining $R_{1.4}$ are found consistently in each of the feature/model selection processes to be (in order of decreasing importance): curvature $K_{sym}$, slope $L$, skewness $J_{sym}$ of nuclear symmetry energy, skewness $J_{0}$, incompressibility $K_{0}$ of symmetric nuclear matter, and the magnitude $E_{sym} (ρ_0)$ of symmetry energy at the saturation density $ρ_0$ of nuclear matter.

description: Endohedral fullerenes, or endofullerenes, are chemical systems of fullerene cages encapsulating single atoms or small molecules. These species provide an interesting challenge of Potential Energy Surface (PES) determination as examples of non-covalently bonded, bound systems. While the majority of studies focus on C$_{60}$ as the encapsulating cage, introducing some anisotropy by using a different fullerene, e.g., C$_{70}$ can unveil a double well potential along the unique axis. By approximating the potential as a pairwise Lennard-Jones (LJ) summation over the fixed C cage atoms, the parameter space of the Hamiltonian includes three tunable variables: $(M,\varepsilon,σ)$ representing the mass of the trapped species, the LJ energy, and length scales respectively. Fixing the mass and allowing the others to vary can imitate the potentials of endohedral species trapped in more elongated fullerenes. We choose to explore the LJ parameter space of an endohedral atom in C$_{70}$ with $\varepsilon\in$ [20cm$^{-1}$, 150cm$^{-1}$], and $σ\in$ [2.85Å , 3.05Å]. As the barrier height and positions of these wells vary between [1cm$^{-1}$, 264cm$^{-1}$] and [0.35Å, 0.85Å] respectively, using a 3D direct product basis of 1D harmonic oscillator (HO) wavefunctions centred at the origin where there is a local maximum is unphysical. Instead we propose the use of a non-orthogonal basis set, using 1D HO wavefunctions centred in each minimum and compare this to other choices. The ground state energy of the X@C$_{70}$ is tracked across the LJ parameter space, along with its corresponding nuclear translational wavefunctions. A classification of the wavefunction characteristics, namely the prolateness and ``peanut-likeness'' based on its statistical moments is also proposed.

description: We present a new family of models that is based on graphs that may have undirected, directed and bidirected edges. We name these new models marginal AMP (MAMP) chain graphs because each of them is Markov equivalent to some AMP chain graph under marginalization of some of its nodes. However, MAMP chain graphs do not only subsume AMP chain graphs but also multivariate regression chain graphs. We describe global and pairwise Markov properties for MAMP chain graphs and prove their equivalence for compositional graphoids. We also characterize when two MAMP chain graphs are Markov equivalent. For Gaussian probability distributions, we also show that every MAMP chain graph is Markov equivalent to some directed and acyclic graph with deterministic nodes under marginalization and conditioning on some of its nodes. This is important because it implies that the independence model represented by a MAMP chain graph can be accounted for by some data generating process that is partially observed and has selection bias. Finally, we modify MAMP chain graphs so that they are closed under marginalization for Gaussian probability distributions. This is a desirable feature because it guarantees parsimonious models under marginalization.

description: This paper studies the market microstructure of pre-industrial Europe. In particu- lar we investigate the institution of the broker in markets and fairs, and develop a unique data set of approximately 1100 sets of brokerage rules in 42 merchant towns in Central and Western Europe from the late 13th to the end of the 17th century. We show that towns implemented brokerage as an e¢ cient matchmaking institution in a two-sided market problem. Furthermore, towns di¤erentiated seller-friendly from buyer-friendlier matching mechanisms. We show that the decision to implement matchmaking mechanisms, and whether these mechanisms would be buyer- or seller friendly, depends on the products in question and the stated policy goals of the town, as well as time and geographic variables.

The chiral condensate is the order parameter for the chiral phase transition, and the dressed Polyakov loop is the order parameter for the deconfinement phase transition. When there is a current mass, critical points for the chiral and deconfinement phase transitions are different in the crossover region. We show that the difference is changed by the gravitational effect.

description: Strong circularly polarized excitation opens up the possibility to generate and control effective magnetic fields in solid state systems, e.g., via the optical inverse Faraday effect or the phonon inverse Faraday effect. While these effects rely on material properties that can be tailored only to a limited degree, plasmonic resonances can be fully controlled by choosing proper dimensions and carrier concentrations. Plasmon resonances provide new degrees of freedom that can be used to tune or enhance the light-induced magnetic field in engineered metamaterials. Here we employ graphene disks to demonstrate light-induced transient magnetic fields from a plasmonic circular current with extremely high efficiency. The effective magnetic field at the plasmon resonance frequency of the graphene disks (3.5 THz) is evidenced by a strong (~1°) ultrafast Faraday rotation (~ 20 ps). In accordance with reference measurements and simulations, we estimated the strength of the induced magnetic field to be on the order of 0.7 T under a moderate pump fluence of about 440 nJ cm-2.

Non-equilibrium phases of Fermi gas inside a cavity with imbalanced pumping

description: In this work, we investigate the non-equilibrium dynamics of one-dimensional spinless fermions loaded in a cavity with imbalanced pumping lasers. Our study is motivated by previous work on a similar setup using bosons, and we explore the unique properties of fermionic systems in this context. By considering the imbalance in the pumping, we find that the system exhibits multiple superradiant steady phases and an unstable phase. Furthermore, by making use of the hysteresis structure of superradiant phases, we propose a unidirectional topological pumping. Unlike the usual topological pumping in which the driving protocol breaks time reversal symmetry, the driving protocol can be time reversal invariant in our proposal.

description: We employ a rich sample of individual tax returns data to simulate alternatives to the income tax reform introduced in Germany by the governmental coalition of Social Democrats and Greens in 1998. We characterize three reforms that would have been fiscally equivalent to the actual one: a distributionally neutral tax reform, one with a maximal basic allowance, and a flat tax. By comparing the individual tax burdens under each alternative, we simulate majority voting on the tax reform. The actual reform loses against both the distributionally neutral reform and the one with maximal basic allowance; however, it wins against the flat tax. The Condorcet winner turns out to be the reform with maximal basic allowance.
description: Gab es zu der rot-grünen Steuerreform eine aufkommensäquivalente Alternative, die eine Mehrheit der Steuerzahler besser gestellt hätte? Und wenn ja, wie hätte eine solche Alternative aussehen können? Auf Basis der Einkommensteuerstatistik 1998 simulieren wir vier aufkommensäquivalente Tarifszenarien: die rot-grüne Steuerreform, eine Erhöhung des Grundfreibetrages, eine verteilungsneutrale Reform und eine Flattax. In einem ersten Schritt untersuchen wir diese Tarifszenarien auf ihre Verteilungswirkungen. Anschließend ermitteln wir durch paarweise Abstimmungen das von den Steuerzahlern präferierte Tarifszenario und zeigen, dass die Erhöhung des Grundfreibetrages Condorcet-Sieger ist. Die rot-grüne Steuerreform hätte lediglich die Wahl gegen die Flattax gewonnen.
Intrinsic Magnetism in Nanosheets of SnO$_{2}$: A First-principles Study

description: We propose intrinsic magnetism in nanosheets of SnO$_{2}$, based on first-principles calculations. The electronic structure and spin density reveal that $p$ orbitals of the oxygen atoms, surrounding Sn vacancies, have a non itinerant nature which gives birth to localized magnetism. A giant decrease in defect formation energies of Sn vacancies in nanosheets is observed. We, therefore, believe that native defects can be stabilized without any chemical doping. Nanosheets of different thicknesses are also studied, and it is found that it is easier to create vacancies, which are magnetic, at the surface of the sheets. SnO$_{2}$ nanosheets can, therefore, open new opportunities in the field of spintronics.

What do we know about the disruption index in scientometrics? An overview of the literature

description: The purpose of this paper is to provide a review of the literature on the original disruption index (DI1) and its variants in scientometrics. The DI1 has received much media attention and prompted a public debate about science policy implications, since a study published in Nature found that papers in all disciplines and patents are becoming less disruptive over time. This review explains in the first part the DI1 and its variants in detail by examining their technicaland theoretical properties. The remaining parts of the review are devoted to studies that examine the validity and the limitations of the indices. Particular focus is placed on (1) possible biases that affect disruption indices (2) the convergent and predictive validity of disruption scores, and (3) the comparative performance of the DI1 and its variants. The review shows that, while the literature on convergent validity is not entirely conclusive, it is clear that some modified index variants, in particular DI5, show higher degrees of convergent validity than DI1. The literature draws attention to the fact that (some) disruption indices suffer from inconsistency, time-sensitive biases, and several data-induced biases. The limitations of disruption indices are highlighted and best practice guidelines are provided. The review encourages users of the index to inform about the variety of DI1 variants and to apply the most appropriate variant. More research on the validity of disruption scores as well as a more precise understanding of disruption as a theoretical construct is needed before the indices can be used in the research evaluation practice.

description: As tecnologias digitais (TD) devem ser colocadas ao serviço das crianças, estimulando a sua curiosidade e aprendizagem. Para além disso, é importante as crianças contactarem com TD de modo a adquirirem tech-handling skills (competências de manuseamento de tecnologias), devendo manuseá-las, explorá-las e aprender-fazendo quando as utilizam. Pretende-se com este artigo dar a conhecer a realização de um projeto na valência de educação pré-escolar, com recurso às TD. O projeto teve como objetivo a exploração de conceitos matemáticos por parte das crianças, como a medição, a organização e tratamento de dados, nomeadamente a recolha de dados, a sua representação em gráficos. Para estas explorações, as crianças tiveram ao seu dispor dois tablets, um sensor de velocidade de vento e um sensor de medição do nível sonoro. Foi utilizada a metodologia de trabalho de projeto, o que significa que a criança foi implicada em processos investigativos, numa lógica socioconstrutivista, sendo agentes principais em todo o desenrolar das atividades. As crianças apropriaram-se facilmente das tecnologias móveis para recolher os dados, analisando-os e retirando conclusões. Sendo este um estudo exploratório, no final apresentam- -se atividades futuras para continuação e aprofundamento do projeto apresentado.

description: Optimum Currency Area (OCA) theory proves inadequate in the analysis of the new regional monetary integration schemes that have sprung up among developing and emerging market economies since the 1990s. Building on the concept of ‘original sin’ developed by Eichengreen et al. we argue that a different conceptual framework is needed as these regional monetary South-South integration (SSI) schemes differ fundamentally from North-South arrangements because they involve none of the international reserve currencies. Insights from the cases of monetary south-south cooperation in Southern Africa, East Asia and Latin America suggest that SSI can have beneficial effects on macroeconomic stability. This paper sketches a first set of hypotheses on the necessary conditions for these stability gains to materialise.

description: The authors previously considered a method solving optimization problems by using a system of interconnected network of two component Bose-Einstein condensates (Byrnes, Yan, Yamamoto New J. Phys. 13, 113025 (2011)). The use of bosonic particles was found to give a reduced time proportional to the number of bosons N for solving Ising model Hamiltonians by taking advantage of enhanced bosonic cooling rates. In this paper we consider the same system in terms of neural networks. We find that up to the accelerated cooling of the bosons the previously proposed system is equivalent to a stochastic continuous Hopfield network. This makes it clear that the BEC network is a physical realization of a simulated annealing algorithm, with an additional speedup due to bosonic enhancement. We discuss the BEC network in terms of typical neural network tasks such as learning and pattern recognition and find that the latter process may be accelerated by a factor of N.
