description: The hot-electron effect in the spin relaxation of electrically injected electrons in intrinsic Germanium is investigated by the kinetic spin Bloch equations both analytically and numerically. It is shown that in the weak-electric-field regime with $E\lesssim 0.5$~kV/cm, our calculations has reasonable agreement with the recent transport experiment in the spin-injection configuration [Phys. Rev. Lett. {\bf 111}, 257204 (2013)]. We reveal that the spin relaxation is significantly enhanced at low temperature in the presence of weak electric field $E\lesssim 50$~V/cm, which originates from the obvious center-of-mass drift effect due to the weak electron-phonon interaction, whereas the hot-electron effect is demonstrated to be less important. This can explain the discrepancy between the experimental observation and the previous theoretical calculation [Phys. Rev. B {\bf 86}, 085202 (2012)], which deviates from the experimental results by about two orders of magnitude at low temperature. It is further shown that in the strong-electric-field regime with $0.5\lesssim E \lesssim 2$~kV/cm, the spin relaxation is enhanced due to the hot-electron effect, whereas the drift effect is demonstrated to be marginal. Finally, we find that when $1.4 \lesssim E\lesssim 2$~kV/cm which lies in the strong-electric-field regime, a small fraction of electrons ($\lesssim 5\%$) can be driven from the L to $Γ$ valley, and the spin relaxation rates are the same for the $Γ$ and L valleys in the intrinsic sample without impurity. With the negligible influence of the spin dynamics in the $Γ$ valley to the whole system, the spin dynamics in the L valley can be measured from the $Γ$ valley by the standard direct optical transition method.

Year: 2022

description: Der erste Teil dieser Arbeit ist ein Versuch, die Schriften Samuel Gradowskis, Mitglied des Sonderkommandos in Auschwitz, anhand der Philosophie Jean-Paul Sartres, insbesondere des Blicks“, zu interpretieren. Der zweite Teil zieht Jacques Lacans Interpretation des Sartre’schen „Blicks“ heran, um die Gedanken, Handlungen und Gefühle der SS-Männer Jürgen Stroop und Franz Stangl zu interpretieren, und zwar anhand von Interviews. Zusammengefasst ist diese Arbeit ein Versuch, die Unmöglichkeit des „Blicks“ und daher auch der Alterität während des systematischen Massenmords an den europäischen Juden besser zu verstehen.
description: In its first part, this work aims to use Jean-Paul Sartre’s philosophy, more specifically his philosophy of the “gaze,” to interpret the manuscripts written by Załmen Gradowski, member of the Sonderkommando in Auschwitz. The second part of this work uses Jacques Lacan’s interpretation of Sartre’s “gaze” to shed light on the thoughts, actions, and feelings of two memebers of the SS, Jürgen Stroop and Franz Stangl, as revealed in prison interviews. In summary, this work attempts to shed light on the impossibility of the “gaze” and thus also of alterity during the deliberate and systematic extermination of the Jewish people of Europe.

description: We present a novel, deterministic, and efficient method to detect whether a given rational space curve is symmetric. By using well-known differential invariants of space curves, namely the curvature and torsion, the method is significantly faster, simpler, and more general than an earlier method addressing a similar problem. To support this claim, we present an analysis of the arithmetic complexity of the algorithm and timings from an implementation in Sage.

description: Abstract The Neotropical evaniid genus Evaniscus Szépligeti currently includes six species. Two new species are described, Evaniscus lansdownei Mullins, sp. n. from Colombia and Brazil and Evaniscus rafaeli Kawada, sp. n. from Brazil. Evaniscus sulcigenis Roman, syn. n., is synonymized under Evaniscus rufithorax Enderlein. An identification key to species of Evaniscus is provided. Thirty-five parsimony informative morphological characters are analyzed for six ingroup and four outgroup taxa. A topology resulting in a monophyletic Evaniscus is presented with Evaniscus tibialis and Evaniscus rafaeli as sister to the remaining Evaniscus species. The Hymenoptera Anatomy Ontology and other relevant biomedical ontologies are employed to create semantic phenotype statements in Entity-Quality (EQ) format for species descriptions. This approach is an early effort to formalize species descriptions and to make descriptive data available to other domains.

description: Wilson Special Collections Library’s Southern Historical Collection holds hundreds of archival collections that document Black people, who were enslaved on plantations and farms, at mills, fisheries, railroads, ports, colleges, and universities, and in towns and cities across the American South during the 18th and 19th centuries. These collections include documents created by the enslavers to manage their assets in the people they claimed as property. The enslavers often recorded information including names, ages, birth dates, death dates occupations, illnesses, and acts of resistance, that cannot be found anywhere else in public records. The documents are available for research, but they are obscured by the archival principle of provenance and by archival description that centers white people and marginalizes Black, Brown, and Indigenous people. This presentation is a call to center Black people in archival description of records of enslavement.

description: Les stéréotypes sont présents dans la société, et donc par prolongement, ils le sont aussi dans les classes. Nous avons choisi de travailler sur ce sujet suite à certaines paroles qui nous ont choquées. Notre travail s’est construit en trois temps. Premièrement, nous avons analysé la vie d’une classe et fait ressortir un stéréotype, celui de genre. Nous avons ensuite mis en place une séquence tentant de déconstruire les représentations genrées des élèves, dans le but de faire évoluer la pensée de certains d’entre eux. Finalement, nous avons analysé les traces récoltées à plusieurs niveaux (interviews, fiches, discussions), afin de déterminer si le processus que nous avons mis en place sur deux semaines a fonctionné ou si la situation est restée la même. Afin de pouvoir déconstruire un préjugé, il est important de comprendre comment il fonctionne, comment il se construit, de sorte à connaître le moment le plus propice pour une intervention. Chaque étape de la construction du préjugé est explicitée dans notre partie théorique. Il y a en premier lieu la catégorisation sociale, à quoi s’ajoute les représentations sociales, puis les stéréotypes apparaissent pour en arriver aux préjugés. Nous abordons également le côté multiculturel et hétérogène d’une classe car c’est l’hétérogénéité qui fait ressortir des pensées puis des comportements différents. Dans un deuxième temps, nous mettons en place une séquence dans la classe-cible. Les élèves sont acteurs dans les activités proposées afin de favoriser une remise en question personnelle. De plus, les discussions et débats ont été privilégiés car il s’agit des moments les plus propices à l’évolution de la pensée. Finalement, nous avons analysé la séquence ainsi que les entretiens et les discussions menées en classe, ce qui nous a permis de mettre en évidence les points forts et les points faibles de cette dernière.

Identifying quantum phases from injectivity of symmetric matrix product states

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: Given a local gapped Hamiltonian with a global symmetry on a one dimensional lattice we describe a method to identify if the Hamiltonian belongs to a quantum phase in which the symmetry is spontaneously broken in the ground states or to a specific symmetry protected phase, without using local or string order parameters. We obtain different matrix product state (MPS) descriptions of the symmetric ground state(s) of the Hamiltonian by restricting the MPS matrices to transform under different projective representations of the symmetry. The phase of the Hamiltonian is identified by examining which MPS descriptions, if any, are injective, namely, whether the largest eigenvalue of the "transfer matrix" obtained from the MPS is unique. We demonstrate the method for translation invariant Hamiltonians with a global SO(3), Z_2 and Z_2 x Z_2 symmetry on an infinite chain.

description: Ce mémoire traite de l’influence de la perception de la maîtrise de la langue allemande qu’a un futur enseignant de l’école primaire sur la mise en oeuvre de la didactique de l’allemand, plus précisément, de l’approche actionnelle. Nous voulions savoir si un enseignant qui perçoit sa maîtrise de la langue comme étant mauvaise n’osera pas mettre en place l’approche actionnelle dans sa classe. Ce travail professionnel est composé de trois parties distinctes. La première, notre cadre théorique, explicite et met lien les différents concepts qui nous ont permis d’élaborer notre recherche. Nous sommes parties de deux piliers principaux pour déterminer nos concepts : la maîtrise de la langue et la didactique de l’allemand. La deuxième partie est constituée de notre recherche qualitative. Nous nous sommes entretenues avec des étudiants de troisième année de la HEP Vaud. En effet, ces étudiants ont déjà suivi deux semestres complets sur la didactique de l’allemand et étaient enclins à participer à cette recherche. Nous avons analysé leurs réponses afin de pouvoir valider ou non les hypothèses que nous avions émises au préalable. Ce travail se termine avec une partie qui comprend les limites de notre recherche ainsi qu’une conclusion qui aboutit notre recherche et qui met en exergue les éléments que cela nous a apportés d’un point de vue personnel.
Holographic time-resolved particle tracking by means of three-dimensional volumetric deconvolution

description: Holographic particle image velocimetry allows tracking particle trajectories in time and space by means of holography. However, the drawback of the technique is that in the three-dimensional particle distribution reconstructed from a hologram, the individual particles can hardly be resolved due to the superimposed out-of-focus signal from neighboring particles. We demonstrate here a three-dimensional volumetric deconvolution applied to the reconstructed wavefront which results in resolving all particles simultaneously in three-dimensions. Moreover, we apply the three-dimensional volumetric deconvolution to reconstructions of a time-dependent sequence of holograms of an ensemble of polystyrene spheres moving in water. From each hologram we simultaneously resolve all particles in the ensemble in three dimensions and from the sequence of holograms we obtain the time-resolved trajectories of individual polystyrene spheres.

AUTRE MATÉRIEL EXAMINÉ. — Madagascar. Prov. Toamasina, Antanambe, au S de Mananara, sur latérite, [16°26’00”S, 49°50’30”E], 10.XI.1964, fl. ♂, Service Forestier 23756 (G, NY, P, TAN, TEF). RÉPARTITION ET ÉCOLOGIE Ivodea nana n’est connue que d’une seule localité, dans les sous-bois des forêts sublittorales sur latérite, d’Antanambe, Mananara-Nord. Les deux récoltes faites par Capuron en 1964 dans cette localité sont les seules connues de cette espèce. PHÉNOLOGIE Floraison: octobre à novembre; fructification: novembre à décembre. NOTES Ivodea nana est morphologiquement similaire à I. confertifolia et I. mahanarica par ses grandes feuilles oblancéolées ou obovales groupées en bouquets denses dans la partie distale des branches, à base aiguë ou atténuée en coin, mais en diffère par l’absence totale d’indument. De plus, elle se distingue d’ I. confertifolia par ses pétioles de 0,5-2(2,5) cm de long nettement plus robustes de (1) 2-4 mm de diamètre (vs pétioles (1,5) 2-4 cm de long et moins robustes de 1-2 mm de diamètre) et d’ I. mahanarica par ses pétioles non ailés (vs pétioles ailés). Elle possède aussi des infrutescences plus longues de 7-14 cm de long (vs plus courtes de 3-7 cm de long chez I. confertifolia et I. mahanarica). Parmi les deux parts de Service Forestier 23757 dans l’herbier de Paris, nous avons choisi comme lectotype celle qui porte des fruits mûrs et qui avait manifestement servi pour l’illustration figurant dans le protologue. STATUT DE CONSERVATION Ivodea nana n’est connue que d’une seule localité dans une aire protégée (Mananara-Nord) qui, malgré son statut, subit néanmoins des pressions anthropiques (tavy et coupe illicite). Avec une zone d’occupation de 10 km ², l’espèce est provisoirement classée comme« Vulnérable » (VU D2) conformément aux critères pour la Liste Rouge de l’UICN (2012).

On generalized entropies and information-theoretic Bell inequalities under decoherence

Publisher: name: arXiv
Year: 2014
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We consider information-theoretic inequalities of the Bell type in the presence of decoherence. It is natural that too strong coupling with the environment can prevent an observation of quantum correlations. In this regard, the use of various entropic functions may give additional capabilities to reveal desired correlations. It was already shown that the Bell and Leggett-Garg inequalities in terms conditional Tsallis entropies are more sensitive in the cases of detection inefficiencies. In this paper, we study capabilities of generalized conditional entropies of the Tsallis type in analyzing the Bell theorem in decoherence scenarios. Two forms of the conditional Tsallis $q$-entropy are known in the literature. We show that each of them can be used for defining a metric in the probability space of interest. Such metrics can be used in realizing the so-called triangle principle. The triangle principle has recently been proposed as a unifying approach to questions of local realism and non-contextuality. Applying the triangle principle leads to the two families of $q$-metric inequalities of the Bell type. Information-theoretic formulations in terms of the $q$-entropic metrics are first discussed for the CHSH scenario in dephasing environment. Then we also revisit $q$-entropic inequalities of the Leggett-Garg type. An environmental influence is modeled by the phase damping channel and by the depolarizing channel.
description: 15 pages, three figures. The title is slightly changed. The version 2 includes a discussion of the Leggett-Garg scenario with trichotomic observables under decoherence. In Section III, curves on Fig. 1 are corrected. The bibliography was revised and updated. Grammatical typos are fixed

description: We study the usability of pre-trained weakly supervised audio tagging (AT) models as feature extractors for general audio representations. We mainly analyze the feasibility of transferring those embeddings to other tasks within the speech and sound domains. Specifically, we benchmark weakly supervised pre-trained models (MobileNetV2 and EfficientNet-B0) against modern self-supervised learning methods (BYOL-A) as feature extractors. Fourteen downstream tasks are used for evaluation ranging from music instrument classification to language classification. Our results indicate that AT pre-trained models are an excellent transfer learning choice for music, event, and emotion recognition tasks. Further, finetuning AT models can also benefit speech-related tasks such as keyword spotting and intent classification.

description: In the framework of relativistic ideal hydrodynamics, we study the production mechanism for vorticity and magnetic field in relativistic ideal fluids. It is demonstrated that in the uncharged fluids the thermal vorticity will always satisfy the Kelvin's theorem and the circulation must be conserved. However, in the charged fluids, the vorticity and magnetic field can be produced by the interaction between the entropy gradients and the fluid velocity gradients. Especially, in the multiple charged fluids, the vorticity and magnetic field can be produced by the interaction between the inhomogenous charge density ratio and the fluid velocity gradients even if the entropy distribution is homogeneous, which provides another mechanism for the production of vorticity and magnetic field in relativistic plasmas or in the early universe.

description: We construct embeddings of $\widehat{\mathfrak{sl}}_2$ in lattice vertex algebras by composing the Wakimoto realization with the Friedan-Martinec-Shenker bosonization. The Kac-Wakimoto hierarchy then gives rise to two new hierarchies of integrable, non-autonomous, non-linear partial differential equations. A new feature of our construction is that it works for any value of the central element of $\widehat{\mathfrak{sl}}_2$; that is, the level becomes a parameter in the equations.

description: Self-sustained reaction fronts in a disordered medium subject to an external flow display self-affine roughening, pinning and depinning transitions. We measure spatial and temporal fluctuations of the front in $1+1$ dimensions, controlled by a single parameter, the mean flow velocity. Three distinct universality classes are observed, consistent with the Kardar-Parisi-Zhang (KPZ) class for fast advancing or receding fronts, the quenched KPZ class (positive-qKPZ) when the mean flow approximately cancels the reaction rate, and the negative-qKPZ class for slowly receding fronts. Both quenched KPZ classes exhibit distinct depinning transitions, in agreement with the theory.

description: Photometric observations for the totally eclipsing binary system TYC 4002-2628-1, were obtained between November 2020 and November 2021. To determine the stellar atmospheric parameters, a spectral image was taken with the 2.16 m telescope at National Astronomical Observatory of China (NAOC). TYC 4002-2628-1 is a low-amplitude (about 0.15 mag for $V$ band), short-period (0.3670495 d), contact eclipsing binary with a total secondary eclipse. Intrinsic light curve variations and the reversal of the O'Connell effect are detected in the light curves, which may be due to spot activity. Based on the photometric solutions derived from the multi-band time series light curves, TYC 4002-2628-1 is an extremely low mass ratio contact binary with a mass ratio of $q\sim$ 0.0482 and a fill-out factor of $f\sim5\%$. By analyzing the $O-C$ variations, we find that its orbital period remains unchanged when BJD < 2458321 . Then the orbital period changed suddenly around BJD 2458743 and has an increasing rate of $dP/dt=1.62\times{10^{-5}}day\cdot yr^{-1}=140$ $second\cdot century^{-1}$ . If confirmed, TYC 4002-2628-1 would be the contact binary with the highest orbital period increasing rate so far. By investigating the ratio of orbital angular momentum to the spin angular momentum ( $J_{orb}$/$J_{spin}$ $<3$) , the instability mass ratio ($q_{inst}/q=1.84$) and the instability separation ($A_{inst}/A=1.35$), TYC 4002-2628-1 can be regarded as a merger candidate.

description: Ce travail a pour objectif d’analyser et de réfléchir à la variété des méthodes relatives à l’enseignement des tables de multiplication et au dispositif didactique mis en place dans les classes vaudoises. Nous souhaitons, par une approche d’observation des pratiques d’enseignant-e-s, déterminer le degré de variation de l’enseignement de cet objet d’apprentissage. La mémorisation du répertoire multiplicatif a une place importante dans le programme de mathématiques de 5e année notamment. Son statut à la fois d’objet et d’outil (Douady, 1986) lui confère un rôle crucial dans la continuité du programme scolaire. En effet, une maîtrise insuffisante des tables de multiplications provoquent des erreurs dans le calcul posé de la multiplication ou de la division (Charnay, 2002) et indique que son statut d’outil est encore à travailler. Au regard de la problématique soulevée, certaines questions nous sont apparues en début de recherche : est-ce que de l’apprentissage par coeur est toujours une méthode très présente dans l’apprentissage des élèves ? Quel est l’ordre d’apprentissage des tables ? Quelles sont les propriétés mathématiques liées à la multiplication qui pourraient favoriser la création de liens et donc agir comme soutien aux apprentissages ? Dans l’intention de comprendre les enjeux de cette problématique, ce travail pose un cadre théorique structuré en trois parties : la première est dédiée au répertoire mémorisé multiplicatif, la deuxième aux méthodes d’apprentissages des tables de multiplication et la troisième touche à la variété des dispositifs en classe. Pour répondre à notre question de recherche, nous avons réalisé des entretiens auprès de professionnel-le-s vaudois-e-s de l’enseignement du cycle 2. L’analyse des réponses des entretiens nous a permis de nourrir notre réflexion et d’amener des éléments de réponses en regard des hypothèses émises et de la question de recherche. La conclusion de ce travail est que les enseignant-e-s varient leur enseignement des tables de manière à répondre à la diversité des apprenant-e-s. Il y a par conséquent une grande variété des dispositifs et outils didactiques possibles pour répondre aux stratégies d’apprentissages elles aussi variée des élèves. Cependant, cette diversité ne garantit pas que les apprentissages seront uniformes pour l’ensemble des élèves.

description: We study deep inelastic scattering at large-'t Hooft coupling and finite $x$ from gauge/string duality beyond single-hadron final states which gives the leading large-$N_c$ contribution. Within the supergravity approximation, we calculate the subleading large-$N_c$ contribution by introducing an extra hadron into the final states. We find the contribution from these double-hadron final states will dominate in the Bjorken limit $q^2\rightarrow \infty$ compared with the single-hadron states. We discuss the implications of our results.

description: Through the two specific problems, the 2D hidden linear function problem and the 1D magic square problem, Bravyi et al. have recently shown that there exists a separation between $\mathbf{QNC^0}$ and $\mathbf{NC^0}$, where $\mathbf{QNC^0}$ and $\mathbf{NC^0}$ are the classes of polynomial-size and constant-depth quantum and classical circuits with bounded fan-in gates, respectively. In this paper, we present another problem with the same property, the magic pentagram problem based on the magic pentagram game, which is a nonlocal game. In other words, we show that the problem can be solved with certainty by a $\mathbf{QNC^0}$ circuit but not by any $\mathbf{NC^0}$ circuits.

description: Most searches for continuous gravitational-waves from pulsars use Taylor expansions in the phase to model the spin-down of neutron stars. Studies of pulsars demonstrate that their electromagnetic (EM) emissions suffer from \emph{timing noise}, small deviations in the phase from Taylor expansion models. How the mechanism producing EM emission is related to any continuous gravitational-wave (CW) emission is unknown; if they either interact or are locked in phase then the CW will also experience timing noise. Any disparity between the signal and the search template used in matched filtering methods will result in a loss of signal-to-noise ratio (SNR), referred to as `mismatch'. In this work we assume the CW suffers a similar level of timing noise to its EM counterpart. We inject and recover fake CW signals, which include timing noise generated from observational data on the Crab pulsar. Measuring the mismatch over durations of order $\sim 10$ months, the effect is for the most part found to be small. This suggests recent so-called `narrow-band' searches which placed upper limits on the signals from the Crab and Vela pulsars will not be significantly affected. At a fixed observation time, we find the mismatch depends upon the observation epoch. Considering the averaged mismatch as a function of observation time, we find that it increases as a power law with time, and so may become relevant in long baseline searches.

description: Non-equilibrium transport properties and energy conversion performance of a molecular photo-voltaic cell are analyzed using the Lindblad master equation within the open quantum systems approach. The method allows us to calculate the dynamics of a system driven by several non-equilibrium sources (a situation we call "strong non-equilibrium"), which is the natural operating condition of photovoltaic cells. We include both coherent and incoherent processes and treat electrons, photon, and phonons on an equal footing. We find that decoherence plays a crucial role in determining both the overall efficiency of the photovoltaic conversion and the optimal energy configuration of the system. Specifically, decoherence leads to better performance, due to a faster relaxation of the excited electrons to the electrodes. We also examine the effect of coherent interference on the efficiency. The approach we propose in this letter is suitable for studying transport and energy conversion in other nanoscale systems at non-equilibrium, where both coherent and incoherent processes take place.

description: Gaze tracking is a useful human-to-computer interface, which plays an increasingly important role in a range of mobile applications. Gaze calibration is an indispensable component of gaze tracking, which transforms the eye coordinates to the screen coordinates. The existing approaches of gaze tracking either have limited accuracy or require the user's cooperation in calibration and in turn hurt the quality of experience. We in this paper propose vGaze, continuous gaze tracking with implicit saliency-aware calibration on mobile devices. The design of vGaze stems from our insight on the temporal and spatial dependent relation between the visual saliency and the user's gaze. vGaze is implemented as a light-weight software that identifies video frames with "useful" saliency information, sensing the user's head movement, performs opportunistic calibration using only those "useful" frames, and leverages historical information for accelerating saliency detection. We implement vGaze on a commercial mobile device and evaluate its performance in various scenarios. The results show that vGaze can work at real time with video playback applications. The average error of gaze tracking is 1.51 cm (2.884 degree) which decreases to 0.99 cm (1.891 degree) with historical information and 0.57 cm (1.089 degree) with an indicator.

description: Modelling semantic similarity plays a fundamental role in lexical semantic applications. A natural way of calculating semantic similarity is to access handcrafted semantic networks, but similarity prediction can also be anticipated in a distributional vector space. Similarity calculation continues to be a challenging task, even with the latest breakthroughs in deep neural language models. We first examined popular methodologies in measuring taxonomic similarity, including edge-counting that solely employs semantic relations in a taxonomy, as well as the complex methods that estimate concept specificity. We further extrapolated three weighting factors in modelling taxonomic similarity. To study the distinct mechanisms between taxonomic and distributional similarity measures, we ran head-to-head comparisons of each measure with human similarity judgements from the perspectives of word frequency, polysemy degree and similarity intensity. Our findings suggest that without fine-tuning the uniform distance, taxonomic similarity measures can depend on the shortest path length as a prime factor to predict semantic similarity; in contrast to distributional semantics, edge-counting is free from sense distribution bias in use and can measure word similarity both literally and metaphorically; the synergy of retrofitting neural embeddings with concept relations in similarity prediction may indicate a new trend to leverage knowledge bases on transfer learning. It appears that a large gap still exists on computing semantic similarity among different ranges of word frequency, polysemous degree and similarity intensity.

description: Considering the Generalized Minimal Supergravity Model (GmSUGRA) in the Minimal Supersymmetric Standard Model (MSSM), we study the Electroweak Supersymmetry (EWSUSY), where the squarks and/or gluino are heavy around a few TeVs while the sleptons, sneutrinos, Bino, Winos, and/or Higgsinos are light within one TeV. We resolves the $(g_μ-2)/2$ discrepancy for the muon anomalous magnetic moment in the Standard Model (SM) successfully and identifies a parameter space where such solutions also have the electroweak fine-tuning measures $Δ_{EW}~16.5$ (6$\%$) and $Δ_{EW}~25$ (4$\%$) without and with the WMAP bounds, respectively. We find that the allowed mass ranges consistent within 3$σ$ of the $g-2$ discrepancy for the lightest neutralino, charginos, stau, stau neutrinos, and first two-family sleptons are $[44,390]$ GeV, $[100,700]$ GeV, $[100,700]$, and $[52,700]$ GeV, respectively. Moreover, our solutions satisfy the latest bounds reported by the ATLAS and CMS Collaborations on electroweakinos and sleptons. The colored sparticles such as light stop, gluinos, and the first two-generation squark masses have been found in the mass ranges of $[500, 3000]$ GeV,[1300, 4300] GeV, and $[1800, 4200]$ GeV, respectively. To obtain the observed dark matter relic density for the Lightest Supersymmetric Particle (LSP) neutralino, we have the bino-wino, LSP neutralino-stau, and LSP neutralino-tau sneutrinos coannihilation scenarios, and the resonance solutions such as $A$-pole, Higgs-pole, and $Z$-pole. We identify the higgsino-like LSP neutralino and display its spin-independent and spin-dependent cross sections with nucleons. We present ten benchmark points which can be tested at the up coming collider searches as well.

Topological s-wave pairing superconductivity with spatial inhomogeneity: Mid-gap-state appearance and robustness of superconductivity

description: We study the quasiparticle spectrum of 2D topological $s$-wave superconductors with the Zeeman magnetic field and the Rashba spin-orbit coupling in the presence of spatial inhomogeneity. Solving the real-space Bogoliubov-de Gennes equations, we focus on the excitations within the superconducting gap amplitude, i.e., the appearance of mid-gap states. Two kinds of potential functions, line-type (a chain of impurities) and point-type (a single impurity) ones are examined to take spatial inhomogeneity into account. The line setting shows a link of the mid-gap states with the gapless surface modes indicated by the bulk-boundary correspondence in topological superfluid. The point one shows that the quasiparticles with mid-gap energy are much easily excited by an impurity when the Zeeman magnetic field increases within the topological number to be unchanged. Thus, we obtain insights into the robustness of a topological superconductor against non-magnetic impurities. Moreover, we derive an effective theory applicable to high magnetic fields. The effective gap is the mixture of the chiral $p$-wave and $s$-wave characters. The former is predominant when the magnetic field increases. Therefore, we claim that a chiral $p$-wave character of the effective gap function creates the mid-gap states.

description: Double Hurwitz numbers enumerating weighted $n$-sheeted branched coverings of the Riemann sphere or, equivalently, weighted paths in the Cayley graph of $S_n$ generated by transpositions are determined by an associated weight generating function. A uniquely determined $1$-parameter family of 2D Toda $τ$-functions of hypergeometric type is shown to consist of generating functions for such weighted Hurwitz numbers. Four classical cases are detailed, in which the weighting is uniform: Okounkov's double Hurwitz numbers, for which the ramification is simple at all but two specified branch points; the case of Belyi curves, with three branch points, two with specified profiles; the general case, with a specified number of branch points, two with fixed profiles, the rest constrained only by the genus; and the signed enumeration case, with sign determined by the parity of the number of branch points. Using the exponentiated quantum dilogarithm function as weight generator, three new types of weighted enumerations are introduced. These determine {\em quantum} Hurwitz numbers depending on a deformation parameter $q$. By suitable interpretation of $q$, the statistical mechanics of quantum weighted branched covers may be related to that of Bosonic gases. The standard double Hurwitz numbers are recovered in the classical limit.
