Particle-wave dichotomy in quantum Monte Carlo: unlocking the quantum correlations

Publisher: name: arXiv

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Here, a dichotomy of particles and waves is employed in a quantum Monte Carlo calculation of interacting electrons. Through the creation and propagation of concurrent stochastic ensembles of walkers in physical space and in Hilbert space one can correctly predict the ground state and the real-time evolution of a single electron interacting with larger quantum system. It is shown that such walker ensembles can be constructed straightforwardly through a stochastic sampling (windowing) applied to the mean-field approximation. Our calculations reveal that the ground state and the real-time evolution of the probability distributions and the decoherence due to the Coulomb interaction in presence of strong ultrashort laser pulse can be accounted for correctly by calculating the density matrix of the electron, without referencing to the quantum many-body state of the whole system.

description: Here we report the fabrication and characterization of fully superconducting quantum interference proximity transistors (SQUIPTs) based on the implementation of vanadium (V) in the superconducting loop. At low temperature, the devices show high flux-to-voltage (up to 0.52$\ \textrm{mV}/Φ_0$) and flux-to-current (above 12$\ \textrm{nA}/Φ_0$) transfer functions, with the best estimated flux sensitivity $\sim$2.6$\ μΦ_0/\sqrt{\textrm{Hz}}$ reached under fixed voltage bias, where $Φ_0$ is the flux quantum. The interferometers operate up to $T_\textrm{bath}\simeq$ 2 $ \textrm{K}$, with an improvement of 70$\%$ of the maximal operating temperature with respect to early SQUIPTs design. The main features of the V-based SQUIPT are described within a simplified theoretical model. Our results open the way to the realization of SQUIPTs that take advantage of the use of higher-gap superconductors for ultra-sensitive nanoscale applications that operate at temperatures well above 1 K.

description: We show how to achieve both fast and hyperuniform dispersions of particles in viscous fluids. To do so, we first extend the concept of critical random organization to chaotic drives. We show how palindromic sequences of chaotic advection cause microscopic particles to effectively interact at long range thereby inhibiting critical self-organization. Based on this understanding we go around this limitation and design sequences of stirring and unstirring which simultaneously optimize the speed of particle spreading and the homogeneity of the resulting dispersions.

description: Many features of a wheelchair affect users' actions in a manual wheelchair, determining the overall mobility performance. Based on an ethnographic study of wheelchair users in India, we develop a trajectory analysis centered on the wheelchair as an artefact and the stages in its lifecycle from design to use. This paper focuses on the decisions made and practices in the production and acquisition phases and the consequences further down the line for the end user. In particular, we focus on how different configurations of the user across production and acquisition can make it difficult for users to find a wheelchair well adapted to their situated needs once they bring the artefact into their home and daily routines.

description: While generativity has become a central topic in the development and evolution of digital platforms, there are relatively few empirical studies of the implications for the practices involved in platformization. In this paper, we explore the concept of socio-technical generativity in the context of a large-scale platformization project in the healthcare sector. We investigate the transition from design to use, and how the process of generativity changes. Our preliminary findings show that generativity is a continuous process that is not limited to existing affordances in the platform and that the controlled top-down practice in design is split into parallel ad hoc practices in use. We discuss challenges related to scale and interconnections as well as the role of the management in generative processes.
The role of standards in defining an ecosystem for Virtual Human Twins (VHTs)

description: The European EDITH infrastructure is building a whole ecosystem for Virtual Human Twins (VHTs) in healthcare. This requires interoperability of the data and computational models constructed based on these data, and thus, a high degree of standardization of data and models, as well as applied workflows, modelling approaches and provenance information for traceability. Such standards are defined by initiatives of the scientific community, such as COMBINE, GA4GH and others, as well as by formal Standard Defining Organizations (SDOs), such as ISO with their technical committees. We introduce the different classes of standards used for EDITH, such as data standards, modelling standards, imaging standards, process and workflow standards, quality standards, provenance standards, biosignal standards and standards for phenotypic data.

description: The coverage probability and average data rate of normalized SNR-based scheduling in a downlink cellular network are derived by modeling the locations of the base stations and users as two independent Poison point processes. The scheduler selects the user with the largest instantaneous SNR normalized by the short-term average SNR. In normalized SNR scheduling, the coverage probability when the desired signal experiences Rayleigh fading is shown to be given by a series of Laplace transforms of the probability density function of interference. Also, a closed-form expression for the coverage probability is approximately achieved. The results confirm that normalized SNR scheduling increases the coverage probability due to the multi-user diversity gain.

description: Motivated by the fact that the low-energy properties of the Kondo model can be effectively simulated in spin chains, we study the realization of the effect with bond impurities in ultracold bosonic lattices at half-filling. After presenting a discussion of the effective theory and of the mapping of the bosonic chain onto a lattice spin Hamiltonian, we provide estimates for the Kondo length as a function of the parameters of the bosonic model. We point out that the Kondo length can be extracted from the integrated real space correlation functions, which are experimentally accessible quantities in experiments with cold atoms.

description: The results of CSCW studies should be more effectively incorporated into software engineering practices. This paper focuses on two concepts supporting software component choice and development in IS architecture: artifact ecologies and data work. Using a case study in telemedicine, we propose MADRAE, an extension of the UML component diagram, for modeling practice-based artifact ecologies that emphasize the necessary data work. In the hospital where we tried MADRAE, it was considered helpful by the head of the IS department to analyze existing artifact ecologies and generate design and architecture proposals.

description: Nonreciprocal electromagnetic devices play an important role in modern optical and microwave technologies. Conventional methods for realizing such systems are incompatible with integrated circuits. With recent advances in integrated photonics, the need for efficient on-chip magnetless nonreciprocal devices is more urgent than ever. This paper leverages space-time engineered asymmetric photonic bandgaps to generate optical isolation. It is shown that a properly designed space-time modulated slab is highly reflective/transparent for opposite directions of propagation. The proposed method requires a low modulation frequency, is magnetless and can achieve very high isolation levels. Experimental proof of concept at microwave frequencies is provided.
title: Supporting Inter-Agency Collaboration in Emergency Management: Recurring Challenges Relevant for CSCW

description: Emergency management requires effective collaboration between different agencies. This work implies several challenges due to a heterogeneous mix of actors with different procedures, practices, and support tools. Despite being focused in various research streams, emergency responders still report challenges with sharing information and establishing shared situational awareness in responding to complex events. The paper presents results from a large-scale digital tabletop exercise that illustrate recurring challenges related to support for collaborative procedures, a communication network structure combining several media, use of geocollaborative tools, and configuration of collaborative environments in co-located operations centers. CSCW researchers are well positioned to further address these challenges and thus make an impact in a domain of high societal importance.

Nonequilibrium thermodynamics and information theory: Basic concepts and relaxing dynamics
Creators: name: Altaner, Bernhard
Publisher: name: arXiv
Year: 2017
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: Thermodynamics is based on the notions of energy and entropy. While energy is the elementary quantity governing physical dynamics, entropy is the fundamental concept in information theory. In this work, starting from first principles, we give a detailed didactic account on the relations between energy and entropy and thus physics and information theory. We show that thermodynamic process inequalities, like the Second Law, are equivalent to the requirement that an effective description for physical dynamics is strongly relaxing. From the perspective of information theory, strongly relaxing dynamics govern the irreversible convergence of a statistical ensemble towards the maximally non-commital probability distribution that is compatible with thermodynamic equilibrium parameters. In particular, Markov processes that converge to a thermodynamic equilibrium state are strongly relaxing. Our framework generalizes previous results to arbitrary open and driven systems, yielding novel thermodynamic bounds for idealized and real processes.
title: Scaling Digital Remote Care Technology: Installed Base Cultivation

Year: 2023

description: Digital remote care is considered a way to address the rising costs of healthcare by moving the treatment of patients to the homes, supporting a shift from episodic to continuous care, and promoting preventive care. However, it is still a challenge for user organizations (e.g., hospitals and health centers) to scale digital remote care to large patients’ populations beyond small-scale pilot projects. Research has shown that the implementation and deployment of digital remote care requires both the reorganization of resources, responsibility, competences in the organization and the development of the existing infrastructures. These processes are therefore challenging, and the existing organizational, infrastructural, and digital capabilities of a user organization seem to play a critical role. Thus, in this paper we address the research question of what is the role of the installed base in the scaling of remote care? We have addressed this question by conducting a case study in primary care setting in Norway. This study contributes to increased insight into how existing socio-technological arrangements affect the configuration, adoption and scaling of digital remote care for people with chronic illness.
Resummation Improved Rapidity Spectrum for Gluon Fusion Higgs Production

description: Gluon-induced processes such as Higgs production typically exhibit large perturbative corrections. These partially arise from large virtual corrections to the gluon form factor, which at timelike momentum transfer contains Sudakov logarithms evaluated at negative arguments $\ln^2(-1) = -π^2$. It has been observed that resumming these terms in the timelike form factor leads to a much improved perturbative convergence for the total cross section. We discuss how to consistently incorporate the resummed form factor into the perturbative predictions for generic cross sections differential in the Born kinematics, including in particular the Higgs rapidity spectrum. We verify that this indeed improves the perturbative convergence, leading to smaller and more reliable perturbative uncertainties, and that this is not affected by cancellations between resummed and unresummed contributions. Combining both fixed-order and resummation uncertainties, the perturbative uncertainty for the total cross section at N$^3$LO$+$N$^3$LL$^\prime_φ$ is about a factor of two smaller than at N$^3$LO. The perturbative uncertainty of the rapidity spectrum at NNLO$+$NNLL$^\prime_φ$ is similarly reduced compared to NNLO. We also study the analogous resummation for quark-induced processes, namely Higgs production through bottom quark annihilation and the Drell-Yan rapidity spectrum. For the former the resummation leads to a small improvement, while for the latter it confirms the already small uncertainties of the fixed-order predictions.

description: The multi-indexed Laguerre and Jacobi polynomials form a complete set of orthogonal polynomials. They satisfy second-order differential equations but not three term recurrence relations, because of the 'holes' in their degrees. The multi-indexed Laguerre and Jacobi polynomials have Wronskian expressions originating from multiple Darboux transformations. For the ease of applications, two different forms of simplified expressions of the multi-indexed Laguerre and Jacobi polynomials are derived based on various identities. The parity transformation property of the multi-indexed Jacobi polynomials is derived based on that of the Jacobi polynomial.

description: Building on CSCW research on knowledge and expertise sharing, this exploratory paper presents examples of how a human call advisor answers citizens where the call advisor takes an active role in helping the caller make their request more precise and contrasts with how a chatbot answers to citizens requests. Previous research about expertise sharing is expanded to also involve expertise sharing with citizens. This paper makes a case for including research of expertise sharing between representatives of the public administration and the citizens in CSCW research, and argue for research on if and how a chatbot in the public sector can share expertise when rules need to be applied to a citizen’s life situation.

description: Equilibrium-independent passive-short (EIPS) systems are a class of systems that satisfy a passivity-like dissipation inequality with respect to any forced equilibria with non-positive passivity indices. This paper presents a geometric approach for finding a passivizing transformation for such systems, relying on their steady-state input-output relation and the notion of projective quadratic inequalities (PQIs). We show that PQIs arise naturally from passivity-shortage characteristics of an EIPS system, and the set of their solutions can be explicitly expressed. We leverage this connection to build an input-output mapping that transforms the steady-state input-output relation to a monotone relation, and show that the same mapping passivizes the EIPS system. We show that the proposed transformation can be implemented through a combination of feedback, feed-through, post- and pre-multiplication gains. Furthermore, we consider an application of the presented passivation scheme for the analysis of networks comprised of EIPS systems. Numerous examples are provided to illustrate the theoretical findings.

description: Analytics tasks manipulate structured data with variants of relational algebra (RA) and quantitative data with variants of linear algebra (LA). The two computational models have overlapping expressiveness, motivating a common programming model that affords unified reasoning and algorithm design. At the logical level we propose Lara, a lean algebra of three operators, that expresses RA and LA as well as relevant optimization rules. We show a series of proofs that position Lara %formal and informal at just the right level of expressiveness for a middleware algebra: more explicit than MapReduce but more general than RA or LA. At the physical level we find that the Lara operators afford efficient implementations using a single primitive that is available in a variety of backend engines: range scans over partitioned sorted maps. To evaluate these ideas, we implemented the Lara operators as range iterators in Apache Accumulo, a popular implementation of Google's BigTable. First we show how Lara expresses a sensor quality control task, and we measure the performance impact of optimizations Lara admits on this task. Second we show that the LaraDB implementation outperforms Accumulo's native MapReduce integration on a core task involving join and aggregation in the form of matrix multiply, especially at smaller scales that are typically a poor fit for scale-out approaches. We find that LaraDB offers a conceptually lean framework for optimizing mixed-abstraction analytics tasks, without giving up fast record-level updates and scans.

The magnetar model of the superluminous supernova GAIA16apd and the explosion jet feedback mechanism (JFM)

description: Under the assumption that jets explode core collapse supernovae in a negative jet feedback mechanism (JFM), I show that rapidly rotating neutron stars are likely to be formed when the explosion is very energetic. Under the assumption that an accretion disk or an accretion belt around the just-formed neutron star launch jets and that the accreted gas spins-up the just-formed neutron star, I derive a crude relation between the energy that is stored in the spinning neutron star and the explosion energy. This relation reads Espin/Eexp~(Eexp/1e52erg). It shows that within the frame of the JFM explosion model of core collapse supernovae, spinning neutron stars, such as magnetars, might have significant energy in super-energetic explosions. The existence of magnetars, if confirmed, such as in the recent super-energetic supernova GAIA16apd, further supports the call for a paradigm shift from neutrino-driven to jet-driven core-collapse supernova mechanisms.

description: There has been increased attention recently on model and modelling within the global science education field. Research has begun to skew towards a competence-based perspective of models and modelling, as teachers are experiencing challenges and do not have the required competence in modelling from either theoretical or empirical perspectives. This study aimed to use a theoretical framework to design teaching interventions which assessed the modelling competence of pre-service science teachers. The study focused on modelling competence in three components: meta-modelling knowledge, modelling practices, and modelling products.

An intervention design was used over a period of seven weeks in the teaching sessions of 38 pre-service science teachers (PST, intervention group) within a science teacher education programme in an opportunistically selected university in China. This was compared to 38 in-service teachers (IST) who received no intervention (comparison group). The performance of both sets of teachers during pre, post, and follow-up tests used a Likert scale questionnaire, semi-structured interviews, a Black Box modelling task, PSTs’ reflective journals, lesson plans, and classroom observations in reflective field notes. Multiple data were triangulated by mix methods. In quantitative analysis, both descriptive and statistical analysis with parametric and non-parametric analysis were applied. A qualitative content analysis approach was used to analysis qualitative data.

Results showed the ISTs outperformed the PSTs in meta-modelling knowledge prior to the teaching intervention, and that they had an almost equal level in modelling practices and products. However, PSTs showed a greater and statistically significant improvement in the three components of modelling competence after receiving the intervention. Additional high-level practices and products were found in the PST group, but not in the IST group. Typically, both groups’ modelling patterns (experimental modelling and expressive modelling) could not be easily changed by teaching interventions. In addition, practices and products were positively related, but no relationships were found between meta-modelling knowledge and the other two. Some teaching activities had a positive effect, while some elements presented a challenge in the development of modelling competence.

The study proposed a theoretical framework of modelling competence with three components. The positive effectiveness of the teaching interventions was confirmed. This study has implications for both policy and practice, for teacher pre-service education as well as for the professional development of in-service teachers. More research is needed into the assessment of process-oriented modelling practices, and the investigation of the development of modelling patterns related to different science teachers' practices in different modelling-based contexts.

description: In this paper, we propose an optimized field/circuit coupling approach for the simulation of magnetothermal transients in superconducting magnets. The approach improves the convergence of the iterative coupling scheme between a magnetothermal partial differential model and an electrical lumped-element circuit. Such a multi-physics, multi-rate and multi-scale problem requires a consistent formulation and a dedicated framework to tackle the challenging transient effects occurring at both circuit and magnet level during normal operation and in case of faults. We derive an equivalent magnet model at the circuit side for the linear and the non-linear settings and discuss the convergence of the overall scheme in the framework of optimized Schwarz methods. The efficiency of the developed approach is illustrated by a numerical example of an accelerator dipole magnet with accompanying protection system.

description: Im islamischen Antisemitismus werden die negativsten Judenbilder aus Christentum und Islam vereint. Nur hier werden die muslimischen Überlieferungen von jüdischer Schwäche und Feigheit mit der paranoiden Vorstellung von Juden als den heimlichen Herrschern der Welt verknüpft. Der nachfolgende Aufsatz untersucht zum einen die wichtigsten Dokumente des islamischen Antisemitismus – das Pamphlet Islam-Judentum (1937), Sayyid Qutbs Our Struggle With the Jews (ca. 1951) und die Charta der Hamas (1988). Er beleuchtet zum anderen die besondere Rolle, die Nazi-Deutschland und dessen arabisch-sprachige Propaganda bei der Entstehung und der Verbreitung dieser spezifischen Form von Judenhass spielte und geht auf die Folgewirkungen der antisemitischen Nazipropaganda im Nahen Osten für die Zeit nach 1945 ein. Ein besonderes Kapitel befasst sich mit der Frage, warum ausgerechnet dieser Aspekt der deutschen Geschichte bei Wissenschafter/inne/n und Politiker/inne/n hierzulande wenig Aufmerksamkeit erfährt. Abschließend werden vor dem Hintergrund neuerer Entwicklungen wie dem Abraham-Abkommen die aktuell wichtigsten Kampagnen des islamischen Antisemitismus vorgestellt.

description: Most studies of digital labor platforms –also known as gig platforms –investigate how workers are affected by platforms through algorithmic control and governance models implemented by platform owners. We draw on platform boundary resource model to review an emerging body of literature that looks at how platform workers cope with this platform-enforced governance through an array of digital circumvention tools. We find that workers make use of several types of such tools including social media, chat groups, and various forms of specialized software. We show what this type of digital circumvention tools are used for, and discuss their challenges and potential impact on labor platform ecosystems.

description: The nature of pulsar-like compact stars is essentially a central question of the fundamental strong interaction (explained in quantum chromo-dynamics) at low energy scale, the solution of which still remains a challenge though tremendous efforts have been tried. This kind of compact objects could actually be strange quark stars if strange quark matter in bulk may constitute the true ground state of the strong-interaction matter rather than Fe^56 (the so-called Witten's conjecture). From astrophysical points of view, however, it is proposed that strange cluster matter could be absolutely stable and thus those compact stars could be strange cluster stars in fact. This proposal could be regarded as a general Witten's conjecture: strange matter in bulk could be absolutely stable, in which quarks are either free (for strange quark matter) or localized (for strange cluster matter). Strange cluster with three-light-flavor symmetry is renamed strangeon, being coined by combining "strange nucleon" for the sake of simplicity. A strangeon star can then be thought as a 3-flavored gigantic nucleus, and strangeons are its constituent as an analogy of nucleons which are the constituent of a normal (micro) nucleus. The observational consequences of strangeon stars show that different manifestations of pulsar-like compact stars could be understood in the regime of strangeon stars, and we are expecting more evidence for strangeon star by advanced facilities (e.g., FAST, SKA, and eXTP).

description: We study the impact of the leading non-renormalizable terms in the effective field theory that describes general extensions of the Standard Model with vector-like quarks. Dropping the usual assumption of renormalizability has several phenomenological consequences for the production and decay of the heavy quarks and also for Higgs physics. The most dramatic effects, including those associated with a long lifetime, occur for vector-like quarks with non-standard quantum numbers.

description: The political economic transformation of developed countries over the past half Century has resulted in widespread social mobility for many individuals. The context is a society where political consensus promoted ‘fairness’ as the potential to succeed through social mobility. For many individuals their aspirations have been fulfilled, for others there has been disappointment as they remain in the position of their parents or even experienced downward mobility. This resonates with the consensus explanation that ‘winning’ or ‘losing’ in the context of structural change polarises society through anti-system voting. Yet, the literature has failed to engage with the process of intergenerational social mobility. In Paper 1, I test how individuals’ social mobility affects the tendency to vote for ‘Brexit’, showing that one’s social origins are nearly as important as current educational or occupational position. Paper 2 develops the analysis to show this origin effect extends to anti-system right support across Europe. Over and above origin and destination effects, the act of upward mobility decreases support for the anti-system right, whereas downward mobility increases support for the anti-system right. Contrastingly, I do not identify any impact from social mobility for those who support the anti-system left. In the second section, I explore the mechanisms behind why social mobility is important for political attitudes. Paper 3 uses panel data to show that going to university makes one less ‘Eurosceptic’. However, this effect is at least as great for those from graduate parental backgrounds as for first generation students, ensuring that there remains a difference in attitudes by socio-economic background. Paper 4 investigates another aspect of political socialisation - birthplace unemployment conditions. I find that being born in a Local Authority with higher unemployment decreases adulthood earnings, makes one more economically ‘left-wing’, and increases the likelihood of voting for the Labour Party.

description: Open Forest is an experimental, practice-based inquiry into forests and forest data that facilitates an imaginative co-creation of feral forest datasets. The project involves a series of experimental, hybrid walks with various forests around the world, inviting participants to explore local ecologies and share their experiences in the form of forest stories. To enable sharing of such personally situated stories, we experiment with diverse speculative material practices and devices, including the online Feral Map – a collaborative dataset of diverse, more-than-human forest experiences and knowledge. Through the experimental forest walks and stories, we explore what can constitute a forest dataset, how it can be produced, and by whom to raise questions about power, values, and structural inequalities that shape forests and their futures. We propose that caring for the futures of forests must be collaborative work. Finding ways to do this labour requires imaginative articulations of technologies, practices and data, an agenda to which CSCW is well positioned to contribute.

description: We propose a hierarchical correlation clustering method that extends the well-known correlation clustering to produce hierarchical clusters applicable to both positive and negative pairwise dissimilarities. Then, in the following, we study unsupervised representation learning with such hierarchical correlation clustering. For this purpose, we first investigate embedding the respective hierarchy to be used for tree preserving embedding and feature extraction. Thereafter, we study the extension of minimax distance measures to correlation clustering, as another representation learning paradigm. Finally, we demonstrate the performance of our methods on several datasets.
