description: The observables associated with a quantum system $S$ form a non-commutative algebra ${\mathcal A}_S$. It is assumed that a density matrix $ρ$ can be determined from the expectation values of observables. But $\mathcal A_S$ admits inner automorphisms $a\mapsto uau^{-1},\; a,u\in {\mathcal A}_S$, $u^*u=u^*u=1$, so that its individual elements can be identified only up to unitary transformations. So since $\mathrm{Tr} ρ(uau^*)= \mathrm{Tr} (u^*ρu)a$, only the spectrum of $ρ$, or its characteristic polynomial, can be determined in quantum mechanics. In local quantum field theory, $ρ$ cannot be determined at all, as we shall explain. However, abelian algebras do not have inner automorphisms, so the measurement apparatus can determine mean values of observables in abelian algebras ${\mathcal A}_M\subset {\mathcal A}_S$ ($M$ for measurement, $S$ for system). We study the uncertainties in extending $ρ|_{{\mathcal A}_M}$ to $ρ|_{{\mathcal A}_S}$ (the determination of which means measurement of ${\mathcal A}_S$) and devise a protocol to determine $ρ|_{{\mathcal A}_S}\equiv ρ$ by determining $ρ|_{{\mathcal A}_M}$ for different choices of ${\mathcal A}_M$. The problem we formulate and study is a generalization of the Kadison-Singer theorem. We give an example where the system $S$ is a particle on a circle and the experiment measures the abelian algebra of a magnetic field $B$ coupled to $S$. The measurement of $B$ gives information about the state $ρ$ of the system $S$ due to operator mixing. Associated uncertainty principles for von Neumann entropy are discussed in the appendix, adapting the earlier work of Białynicki-Birula and Mycielski to the present case.

description: Når titlen på denne artikel er Pædagogisk praksis på
selvpsykologisk grundlag – med vægt på evaluering
skyldes det, at jeg dels ønsker at sige noget om de
erfaringer min kollega og jeg har med at implementere
selvpsykologien1 i pædagogisk sammenhæng,
og dels ønsker at gøre opmærksom på den
katalyserende effekt, teoretiske overvejelse kan
have i forhold til at opkvalificere forskellige pædagogiske
praksissammenhænge. Specielt ønsker jeg
også at sige noget om, hvordan der evalueres på
de pædagogiske indsatser min kollega og jeg har
udviklet på selvpsykologisk grundlag, så vi kan vide
os tilstrækkeligt sikre på, at de faktisk har positiv
effekt i forhold til deres indsatsområde. Hvordan
kan man som professionspraktiker vide, at der sker
en kvalitetsudvikling med denne type indsats?
Artiklen vil belyse disse forhold med mobbe- og
trivselsproblemer i skolen som indsatsområdet.

description: We propose a mixture model of open clusters (OCs) in the color-magnitude diagrams (CMDs) to measure the OC properties, including isochrone parameters (age, distance, metallicity, and dust extinction), stellar mass function (MF), and binary parameters (binary fraction and mass-ratio distribution), with high precision and reliability. The model treats an OC in the CMD as a mixture of single and binary member stars and field stars in the same region. The cluster members are modeled using a theoretical stellar model, MF and binary properties. The field component is modeled nonparametrically using a separate field-star sample in the vicinity of the cluster. Unlike conventional methods that rely on stringent member selection, ours allows us to use a sample of more complete cluster members and attendant field stars. The larger star sample reduces the statistical error and diminishes the potential bias by retaining more stars that are crucial for age estimation and MF measurement. After validating the method with 1000 mock clusters, we measured the parameters of 10 real OCs using Gaia EDR3 data. The best-fit isochrones are consistent with previous measurements in general but with more precise age estimates for several OCs. The inferred MF slope is -2.7 to -1.6 for clusters younger than 2 Gyr, while older clusters appear to have significantly flatter MFs. The binary fraction is 30% to 50%. The photometric and astrometric distances agree well.

Kerr-Newman black hole lensing of relativistic massive particles in the weak field limit

Year: 2021

description: The gravitational lensing of relativistic neutral massive particles caused by a Kerr-Newman black hole is investigated systematically in the weak-field limit. Based on the Kerr-Newman metric in Boyer-Lindquist coordinates, we first derive the analytical form of the equatorial gravitational deflection angle of a massive particle in the third post-Minkowskian approximation. The resulting bending angle, which is found to be consistent with the result in the previous work, is adopted to solve the popular Virbhadra-Ellis lens equation. The analytical expressions for the main observable properties of the primary and secondary images of the particle source are thus obtained beyond the weak-deflection limit, within the framework of standard perturbation theory. The observables include the positions, magnifications, and gravitational time delays of the individual images, the differential time delay, and the total magnification and centroid position. The explicit forms of the correctional effects induced by the deviation of the initial velocity of the massive particle from the speed of light on the observables of the lensed images are then achieved. Finally, serving as an application of the formalism, the supermassive black hole at the Galactic center, Sagittarius A$^{\ast}$, is modeled to be a Kerr-Newman lens. The magnitudes of the velocity-induced correctional effects on the practical lensing observables as well as the possibilities to detect them in this scenario are also analyzed.

We describe the design principles, the optimization and the resulting performance as compared to the CPU version, using both an average cost GPU and high-end NVidia GPU cards (V100 and the latest A100). The results show a substantial acceleration for the fluid solver reaching up to 200 GLUPS (Giga Lattice Updates Per Second) on a cluster made of 512 A100 NVIDIA cards simulating a grid of eight billion lattice points. These results open attractive prospects for the computational design of new materials based on colloidal particles.

description: Motivated by the observed ratio of dark matter to baryon mass densities, $ρ_D/ρ_B \simeq 5$, we propose a theory of dark-color unification. In this theory, the dark to visible baryon masses are fixed by the ratio of dark to visible confinement scales, which are determined to be nearby in mass through the unification of the dark and visible gauge theories at a high scale. Together with a mechanism for darko-baryo-genesis, which arises naturally from the grand unification sector, the mass densities of the two sectors must be nearby, explaining the observed mass density of dark matter. We focus on the simplest possible example of such a theory, where Standard Model color $SU(3)_C$ is unified with dark color $SU(2)_D$ into $SU(5)$ at an intermediate scale of around $10^8-10^9$ GeV. The dark baryon consists of two dark quarks in an isotriplet configuration. There are a range of important cosmological, astrophysical and collider signatures to explore, including dark matter self-interactions, early matter domination from the dark hadrons, gravitational wave signatures from the hidden sector phase transition, contributions to flavor observables, as well as Hidden Valley-like signatures at colliders.

description: Intersecting branes provide a useful mechanism to construct particle physics models from string theory with a wide variety of desirable characteristics. The landscape of such models can be enormous, and navigating towards regions which are most phenomenologically interesting is potentially challenging. Machine learning techniques can be used to efficiently construct large numbers of consistent and phenomenologically desirable models. In this work we phrase the problem of finding consistent intersecting D-brane models in terms of genetic algorithms, which mimic natural selection to evolve a population collectively towards optimal solutions. For a four-dimensional ${\cal N}=1$ supersymmetric type IIA orientifold with intersecting D6-branes, we demonstrate that $\mathcal{O}(10^6)$ unique, fully consistent models can be easily constructed, and, by a judicious choice of search environment and hyper-parameters, $\mathcal{O}(30\%)$ of the found models contain the desired Standard Model gauge group factor. Having a sizable sample allows us to draw some preliminary landscape statistics of intersecting brane models both with and without the restriction of having the Standard Model gauge factor.

Teleparallelism in the algebraic approach to extended geometry

Publisher: name: arXiv
Year: 2021
Subjects: subject: High Energy Physics - Theory (hep-th)

description: Extended geometry is based on an underlying tensor hierarchy algebra. We extend the previously considered $L_\infty$ structure of the local symmetries (the diffeomorphisms and their reducibility) to incorporate physical fields, field strengths and Bianchi identities, and identify these as elements of the tensor hierarchy algebra. The field strengths arise as generalised torsion, so the naturally occurring complex in the $L_\infty$ algebra is $\ldots\leftarrow$ torsion BI's $\leftarrow$ torsion $\leftarrow$ vielbein $\leftarrow$ diffeomorphism parameters $\leftarrow\ldots$ In order to obtain equations of motion, which are not in this complex, (pseudo-)actions, quadratic in torsion, are given for a large class of models. This requires considering the dual complex. We show how local invariance under the compact subgroup locally defined by a generalised metric arises as a "dual gauge symmetry" associated with a certain torsion Bianchi identity, generalising Lorentz invariance in the teleparallel formulation of gravity. The analysis is performed for a large class of finite-dimensional structure groups, with $E_5$ as a detailed example. The continuation to infinite-dimensional cases is discussed.

description: Despite empirical successes of recurrent neural networks (RNNs) in natural language processing (NLP), theoretical understanding of RNNs is still limited due to intrinsically complex non-linear computations. We systematically analyze RNNs' behaviors in a ubiquitous NLP task, the sentiment analysis of movie reviews, via the mapping between a class of RNNs called recurrent arithmetic circuits (RACs) and a matrix product state (MPS). Using the von-Neumann entanglement entropy (EE) as a proxy for information propagation, we show that single-layer RACs possess a maximum information propagation capacity, reflected by the saturation of the EE. Enlarging the bond dimension beyond the EE saturation threshold does not increase model prediction accuracies, so a minimal model that best estimates the data statistics can be inferred. Although the saturated EE is smaller than the maximum EE allowed by the area law, our minimal model still achieves ~99% training accuracies in realistic sentiment analysis data sets. Thus, low EE is not a warrant against the adoption of single-layer RACs for NLP. Contrary to a common belief that long-range information propagation is the main source of RNNs' successes, we show that single-layer RACs harness high expressiveness from the subtle interplay between the information propagation and the word vector embeddings. Our work sheds light on the phenomenology of learning in RACs, and more generally on the explainability of RNNs for NLP, using tools from many-body quantum physics.

description: The worldsheet S matrix of strings on the $AdS_3\times S^3\times T^4$ background is almost entirely fixed by symmetries, up to five functions -- the dressing factors. These must satisfy several consistency conditions, in particular a set of crossing equations. We find that the existing proposal for the dressing factors, while crossing invariant, violates some of these consistency conditions. We put forward a new set of dressing factors and discuss in detail their analytic properties in the string and mirror region, as well as under bound-state fusion.

Det gælder, uanset om det, der evalueres, er menneskers tilegnelse af viden og kompetencer, undervisning og lærerindsats, skoler og uddannelsesinstitutioner eller uddannelsesprogrammer og lovgivning. I alle disse tilfælde har evaluering også andre formål, som fx at kontrollere overholdelsen af besluttede regler og at give symbolsk udtryk for, at der gøres en indsats. Men mange af de mere specifikke målsætninger med evaluering kan i et overordnet perspektiv betragtes som bidrag til udvikling og forbedring.

Evaluering som udvikling

description: Udvikling er det grundlæggende formål med evaluering. Al evaluering handler om feedback, det vil sige tilbageføring af information om styring og organisering med henblik på at stimulere til forbedringer af denne styring og denne organisering. Udtrykket ”evaluering” må absolut ikke afgrænses, så denne idé om feedback falder uden for begrebet. Udviklingsorienteret evaluering kan have mange former som for eksempel selvvurdering, bedømmelse af kolleger og samarbejdspartnere samt brugerevaluering. Den kan være formativ og summativ. To problemer med udviklingsorienteret evaluering er tilbøjeligheder til Potemkin-kulisser og forekomster af sociale fælder. Ud over udvikling kan evaluering også have kontrol og grundviden som formål.

description: Alle mennesker har en personlighed. Og de fleste har personlige kompetencer. Uddannelse i et vidensamfund har i de seneste 10 år fokuseret på at støtte den lærendes personlige udvikling. Men det er svært at støtte en udvikling, som er svær at evaluere. Grundlæggende savnes redskaber og modeller til at evaluere vigtige personlige kompetencer. Denne artikel viser, at det hverken nytter at drukne de lærende i nationale evalueringsstandarder med kompetencer, eller at reducere evaluering til alene ”det”, elever og lærere umiddelbart mener, der er sket i skolens undervisning. En mere konstruktiv vej handler om at forene skolens rammer for undervisning med elevernes erkendelser i forbindelse med de veje, deres læring fører dem igennem. Personligheden træder frem idet eleverne forholder sig aktivt til det, de er i gang med at lære. Her er afsættet til en vedkommende evaluering, også af elevernes personlige kompetencer.

The Full Quadratic Metric-Affine Gravity (Including Parity Odd Terms): Exact solutions for the Affine-Connection

description: We consider the most general Quadratic Metric-Affine Gravity setup in the presence of generic matter sources with non-vanishing hypermomentum. The gravitational action consists of all $17$ quadratic invariants (both parity even and odd) in torsion and non-metricity as well as their mixings, along with the terms that are linear in the curvature namely the Ricci scalar and the totally antisymmetric Riemann piece. Adding also a matter sector to the latter we first obtain the field equations for the generalized quadratic Theory. Then, using a recent Theorem, we successfully find the exact form of the affine connection under some quite general non-degeneracy conditions. Having obtained the exact and unique solution of the affine connection we subsequently derive the closed forms of spacetime torsion and non-metricity and also recast the metric field equations into a GR form with modified source terms that are quadratic in the hypermomentum and linear in its derivatives. We also study the vacuum quadratic Theory and prove that in this instance, or more generally for vanishing hypermomentum, the connection becomes the Levi-Civita one. Therefore, we also find exactly to what does the quadratic vacuum Theory correspond to. Finally, we generalize our result even further and also discuss the physical consequences and applications of our study.

description: We study the holographic realization of optimized correlation measures -- measures of quantum correlation that generalize elementary entropic formulas -- in two-dimensional thermal states dual to spacetimes with a black hole horizon. We consider the symmetric bipartite optimized correlation measures: the entanglement of purification, Q-correlation, R-correlation, and squashed entanglement, as well as the mutual information, a non-optimized correlation measure, and identify the bulk surface configurations realizing their geometric duals over the parameter space of boundary region sizes and the black hole radius. This parameter space is divided into phases associated with given topologies for these bulk surface configurations, and first-order phase transitions occur as a new topology of bulk surfaces becomes preferred. The distinct phases can be associated with different degrees of correlation between the boundary regions and the thermal environment. The Q-correlation has the richest behavior, with a structure of nested optimizations leading to two topologically distinct bulk surface configurations being equally valid as geometric duals at generic points in the phase diagram.

description: This article introduces a new data-driven approach that leverages a manifold embedding generated by the invertible neural network to improve the robustness, efficiency, and accuracy of the constitutive-law-free simulations with limited data. We achieve this by training a deep neural network to globally map data from the constitutive manifold onto a lower-dimensional Euclidean vector space. As such, we establish the relation between the norm of the mapped Euclidean vector space and the metric of the manifold and lead to a more physically consistent notion of distance for the material data. This treatment in return allows us to bypass the expensive combinatorial optimization, which may significantly speed up the model-free simulations when data are abundant and of high dimensions. Meanwhile, the learning of embedding also improves the robustness of the algorithm when the data is sparse or distributed unevenly in the parametric space. Numerical experiments are provided to demonstrate and measure the performance of the manifold embedding technique under different circumstances. Results obtained from the proposed method and those obtained via the classical energy norms are compared.

description: We show that for the Kuramoto model (with identical phase oscillators equally coupled) its global statistics and size of the basins of attraction can be estimated through the eigenvalues of all stable (frequency) synchronized states. This result is somehow unexpected since, by doing that, one could just use local analysis to obtain global dynamic properties. But recent works based on Koopman and Perron-Frobenius operators demonstrate that global features of a nonlinear dynamical system, with some specific conditions, are somehow encoded in the local eigenvalues of its equilibrium states. Recognized numerical simulations in the literature reinforce our analytical results.

Superconductivity on ScH$_{3}$ and YH$_{3}$ hydrides: Effects of applied pressure in combination with electron- and hole-doping on the electron-phonon coupling properties

description: The implementation of electron- and hole-doping, in conjunction to applied pressure, is analyzed as a mechanism to induce or enhance the superconducting state on fcc YH$_3$ and ScH$_3$. In particular, the evolution of their structural, electronic, and lattice dynamical properties, as well as the electron-phonon coupling and superconducting critical temperature ($T_c$) is presented and discussed, as a function of the electron- and hole-doping content as well as applied pressure. The study was performed within the density functional perturbation theory, taking into account the effects of zero-point energy through the quasi-harmonic approximation, while the doping was implemented by means of the construction of the Sc$_{1-x}$M$_{x}$H$_{3}$ (M=Ca,Ti) and Y$_{1-x}$M$_{x}$H$_{3}$ (M=Sr,Zr) solid solutions modeled with the virtual crystal approximation (VCA). We found that the ScH$_3$ and YH$_3$ hydrides shown a significant improvement of their electron-phonon coupling properties under hole-doping (M=Ca,Sr) and at pressure values close to dynamical instabilities. Instead, by electron-doping (M=Ti,Zr), the systems do not improve such properties, whatever value of applied pressure is considered. Then, as a result, $T_c$ rapidly increases as a function of $x$ on the hole-doping region, reaching its maximum value of $92.7(67.9)$~K and $84.5(60.2)$~K at $x=0.3$ for Sc$_{1-x}$Ca$_{x}$H$_{3}$ at $10.8$~GPa and Y$_{1-x}$Sr$_{x}$H$_{3}$ at $5.8$~GPa respectively, with $μ^{*}=0(0.15)$, while for both, electron- and hole-doping, $T_c$ decreases as a function of the applied pressure, mainly due to phonon hardening. By the thorough analysis of the electron-phonon properties as a function of doping and pressure, we can conclude that the tuning of the lattice dynamics is a promising path for improving the superconductivity on both systems.

Complexity growth in Gubser-Rocha models with momentum relaxation

description: The Einstein-Maxwell-Axion-Dilaton (EMAD) theories, based on the Gubser-Rocha (GR) model, are very interesting in holographic calculations of strongly correlated systems in the condensed matter physics. Due to the presence of spatially dependent massless axionic scalar fields, the momentum is relaxed and we have no translational invariance at finite charge density. It would be of interest to study some aspects of quantum information theory for such systems in the context of $AdS/CFT$ where EMAD theory is a holographic dual theory. For instance, in this paper we investigate the complexity and its time dependence for charged $AdS$ black holes of EMAD theories in diverse dimensions via the complexity equals action (CA) conjecture. We will show that the growth rate of the holographic complexity violates the Lloyd's bound at finite times. However, as shown at late times, it depends on the strength of momentum relaxation and saturates the bound for these black holes.

description: IASS Workshop Summary
description: Die öffentliche Debatte über die Gestaltung des digitalen Wandels gewinnt an Dynamik. Nachhaltigkeit, vor allem im sozial-ökologischen Sinn, spielt dabei aktuell jedoch eine untergeordnete Rolle, wenngleich eine zunehmende Zahl an Akteuren der deutschen Nachhaltigkeitswissenschaft sich mit den Auswirkungen der Digitalisierung kritisch auseinandersetzen. Wenn Digitalisierung im öffentlichen Diskurs doch mit Nachhaltigkeit in Verbindung gebracht wird, so erfolgt dies oft sehr eindimensional, bspw. bezogen auf die Frage nach der Zukunft der Arbeit oder das Potential digitaler Technologien als Enabler nachhaltiger Entwicklung. Eine Betrachtung der Nicht-Nachhaltigkeiten der Digitalisierung und des möglichen Zusammenspiels der sozialen, ökologischen und ökonomischen Auswirkungen der Digitalisierung und ihren Folgen für die Gesellschaft ist zumeist nachrangig.
Vor diesem Hintergrund fand am 23. November 2017 ein Roundtable von VertreterInnen aus Wissenschaft und wissenschaftsnahen zivilgesellschaftlichen Organisationen (siehe Anhang) zum Thema „Die Digitalisierung gestalten – Wissenschaft im Spannungsfeld zwischen digitaler und Nachhaltigkeitstransformation“ statt. Der Roundtable widmete sich der Frage, wie Wissenschaft – und Nachhaltigkeitsforschung im Besonderen – einen gesellschafts- und politikrelevanten Beitrag zu einer nachhaltigen Gestaltung des digitalen Wandels leisten kann. Eingeleitet wurde er von einem Impulsvortrag des Ökonomen und Nachhaltigkeitsforschers Prof. Dr. André Reichel. Ziel des Roundtables war eine kritische Reflexion der Herausforderungen, die das Themenfeld „Digitalisierung und Nachhaltigkeit“ an die Wissenschaft stellt, und der Anstoß einer Diskussion zur Rolle der Nachhaltigkeitsforschung im digitalen Wandel.
Dieser Bericht hält zentrale Denkanstöße für die Forschung zu Digitalisierung und Nachhaltigkeit fest, die sich aus der Diskussion im Rahmen des Roundtables ergeben haben.

description: Purpose: The purpose of this study was to extend previous work using a pilot delayed cohort design with a more geographically and linguistically diverse group of people with aphasia (PWA) to explore the impact of a virtual, adapted, and aphasia-friendly yoga program; expand our original outcome measures to include a self-report of aphasia impact in addition to measures of resilience, stress, sleep disturbance, and pain management; and continue programmatic development through participant feedback about the program structure.Method: A delayed cohort design was used to document the benefits of a virtual, adapted, and aphasia-friendly yoga program for persons with moderate–severe aphasia, replicating our previous work with persons with mild–moderate aphasia. Fourteen PWA participated in an 8-week community yoga program. Perceived stress, resilience, sleep disturbance, pain management, and aphasia impact were assessed pre- and postparticipation in the yoga program via self-report. A brief questionnaire was given at the end of the yoga program to inform programmatic development.Results: Results of group comparisons suggest that participation in an 8-week adapted yoga program may positively impact perceptions of resilience (medium effect), sleep disturbance (medium effect), perceived stress (small effect), and aphasia impact (small effect). No effect was found for pain. Overall, participants reported a positive experience and offered feedback to enhance the structure of the program.Conclusions: Findings are promising and support yoga as a potent adjunct to traditional rehabilitation efforts to support resilience and psychosocial variables that impact quality of life in people with moderate–severe aphasia.Supplemental Material S1.

description: We discuss the evolution of the quantum state of an ensemble of atoms that are coupled via a single propagating optical mode. We theoretically show that the quantum state of N atoms, which are initially prepared in the timed Dicke state, evolves through all the N - 1 states that are subradiant with respect to the propagating mode. We predict this process to occur for any atom number and any atom-light coupling strength. These findings are supported by measurements performed with cold cesium atoms coupled to the evanescent field of an optical nanofiber. We experimentally observe the evolution of the state of the ensemble passing through the first two subradiant states, leading to sudden, temporary switch-offs of the optical power emitted into the nanofiber. Our results contribute to the fundamental understanding of collective atom-light interaction and apply to all physical systems, whose description involves timed Dicke states.
