description: Ce travail a pour but l’étude de la perception de l’attitude de la Suisse durant la Seconde Guerre Mondiale au travers de manuels scolaires utilisés dans le canton de Vaud, durant une période allant de 1945 à 2019. Il contient premièrement une partie théorique, composée d’explications de certains concepts (entre autres celui de « manuel scolaire ») et d’éléments permettant de placer l’étude dans son contexte, notamment en ce qui concerne l’histoire scolaire et générale de la Suisse durant la période analysée. Un accent particulier est mis sur l’histoire de la Suisse durant la Seconde Guerre Mondiale et sur les critiques faites à la Confédération durant la période d’ « après-guerre », notamment concernant le refoulement de réfugiés juifs aux frontières suisses durant le conflit et la conservation d’or volé venant d’Allemagne nazie par les banques du pays. Afin de traiter ce sujet avec le plus de précision possible, le rapport de la Commission Indépendante d’Expert (CIE) est souvent cité dans ce travail. La deuxième partie du travail est composée d’une étude comparative de quatre manuels scolaires, utilisés dans le canton de Vaud durant une période allant de 1945 à 2019, soit Histoire de la Suisse, par Georges Michaud, édité en 1947, Histoire générale de 1789 à nos jours, par Georges-André Chevallaz, édité en 1957, Histoire Générale, époque contemporaine, par Jean Christophe Bourquin, édité en 1995 et enfin Histoire 11ème, sciences humaines et sociales, en cours d’édition. L’étude a été menée au moyen de tableaux (en annexe), permettant de comparer l’aspect général des manuels, la structure des parties analysées, et les manières d’aborder les thématiques liées à la Seconde Guerre Mondiale, au niveau international et au niveau de la Suisse. L’étude a pour but de répondre à la question de recherche suivante : Comment le rôle joué par la Suisse durant Seconde Guerre Mondiale est-il représenté au travers des manuels d’histoires vaudois ? Le travail se termine par un compte rendu des éléments mis en lumière grâce à l’étude et par la proposition de questions de plongement.

description: We investigate which pure states of $n$ photons in $d$ modes can be transformed into each other via linear optics, without post-selection. In other words, we study the local unitary (LU) equivalence classes of symmetric many-qudit states. Writing our state as $f^\dagger|Ω\rangle$, with $f^\dagger$ a homogeneous polynomial in the mode creation operators, we propose two sets of LU-invariants: (a) spectral invariants, which are the eigenvalues of the operator $ff^\dagger$, and (b) moments, each given by the norm of the symmetric component of a tensor power of the initial state, which can be computed as vacuum expectation values of $f^k(f^\dagger)^k$. We provide scheme for experimental measurement of the later, as related to the post-selection probability of creating state $f^{\dagger k}|Ω\rangle$ from $k$ copies of $f^{\dagger}|Ω\rangle$.

description: Les outils numériques font aujourd’hui largement partie du quotidien dans notre société. Leur intégration dans les écoles est, cependant, source de nombreux débats et difficultés. Ce qu’on appelle les « TIC » – Technologies de l’Information et de la Communication – sont des outils utilisés dans le monde de l’art, en tant que technique et en tant que médium de création. De nombreux enseignants d’arts visuels voient donc leur potentiel artistique, mais également pédagogique. Les élèves d’aujourd’hui sont nés et évoluent dans un monde numérique, et leurs futurs métiers sont de plus en plus dépendants de savoir-faire technologique. Particulièrement dans les métiers créatifs, où les outils numériques et logiciels de création sont aujourd’hui déjà un pré-requis. Il se pose alors la question de comment préparer les élèves à cette réalité tout en leur transmettant des savoirs disciplinaires. Ces outils sont-ils motivants pour les élèves, favorisent-ils les apprentissages? Ou sont-ils au contraire de simples « gadgets » qui menacent de prendre la place de certaines pratiques traditionnelles? Ce travail explore quelques facettes de ces outils numériques et leur lien au monde de l’art, aborde la question de l’impact sociétal des nouvelles technologies et leur utilisation par les adolescents, ainsi que leur potentiel dans l’enseignement des art visuels et leur impact sur la motivation des élèves.

description: Le présent mémoire s’attache à tenter de comprendre le rapport au savoir des élèves du secondaire 1 dans le canton de Vaud. Pour ce faire, nous avons articuler notre cadre méthodologique autour de trois auteurs : S. Kahn, P. Perrenoud, B. Charlot. Les deux premiers analysent le rôle de l’école comme instrument de domination d’une classe sociale sur les autres. L’école favoriserait la classe moyenne-supérieure en s’appuyant sur la répartition VG et VP par exemple. Ainsi, l’institution scolaire fabrique la réussite et l’échec et ceux qui ne possèdent pas le capital culturel adéquat auraient plus de probabilités d’échouer. Pourtant, le capital culturel seul n’explique pas tout. L’expérience et le rapport au monde de l’élève sont également des éléments à prendre en compte nous dit B. Charlot. Ainsi, la présente étude s’est basée sur les travaux de cet auteur pour mener huit entretiens à quatre filles et quatre garçons évoluant en 11e VP et VG. Ces entretiens semi-directifs se basent sur la méthodologie de l’analyse par théorisation ancrée. Au bout du compte, l’objectif est d’analyser le rapport au savoir des élèves interrogés afin de dresser un portrait idéal-typique de ce rapport. Si les réponses différent peu entre les élèves, le milieu socio-économique homogène des personnes interrogées peut l’expliquer. L’étude a montré que les hypothèses de B. Charlot, réalisée après l’analyse d’entretiens menés auprès de jeunes inscrits dans des lycées professionnels français, sont à nuancer à la suite de nos entretiens. L’objectif final de notre travail est de tenter d’amener des éléments des réponses face aux défis de différenciation pédagogique, en prenant en compte le rapport au savoir de chaque élève.

description: Generically, the black brane solution with planar horizons is thermodynamically stable. We find a counter-example to this statement by demonstrating that an anisotropic black brane is unstable. We present a charged black brane solution dual to a spatially anisotropic finite temperature $\mathcal{N}=4$ super Yang-Mills plasma at finite $U(1)$ chemical potential. This static and regular solution is obtained both numerically and analytically. We uncover rich thermodynamic phase structures for this system by considering the cases when the anisotropy constant "a" takes real and imaginary values, respectively. In the case $a^2>0$, the phase structure of this anisotropic black brane is similar to that of Schwarzschild-AdS black hole with $S^3$ horizon topology, yielding a thermodynamical instability at smaller horizon radii. For the condition $a^2\leq 0$, the thermodynamics is dominated by the black brane phase for all temperatures.

Subjects: subject: Classical Analysis and ODEs (math.CA)

description: We study Riesz and Bessel potentials in the settings of Hankel transform, modified Hankel transform and Hankel-Dunkl transform. We prove sharp or qualitatively sharp pointwise estimates of the corresponding potential kernels. Then we characterize those $1\le p,q \le \infty$, for which the potential operators satisfy $L^p-L^q$ estimates. In case of the Riesz potentials, we also characterize those $1\le p,q \le \infty$, for which two-weight $L^p-L^q$ estimates, with power weights involved, hold. As a special case of our results, we obtain a full characterization of two power-weight $L^p-L^q$ bounds for the classical Riesz potentials in the radial case. This complements an old result of Rubin and its recent reinvestigations by De Nápoli, Drelichman and Durán, and Duoandikoetxea.

description: Ce travail de mémoire s’intéresse aux illustrations représentant des personnes dans deux générations de manuels d’histoire utilisés dans les classes vaudoises du secondaire I. Le premier est le manuel Le Moyen Âge. Les Temps modernes édité conjointement par Loisirs et pédagogie S.A. (LEP) ainsi qu’Edipresse Livres S.A., en 1994, dans sa version A. Il a été utilisé de 1994 à 2011 dans les classes des divisions prégymnasiales et supérieures. La deuxième génération de manuels étudiée comporte des chapitres sélectionnés dans les futurs MER qui seront destinés aux élèves de 9e et 10e années Harmos (voie prégymnasiale et générale) dès la rentrée scolaire 2019-2020 et qui répondront aux exigences du PER (plan d’études romand). Ces chapitres ont été choisis afin de correspondre aux thématiques étudiées dans le manuel LEP. Notre analyse se penche sur les représentations iconographiques des figures masculines et féminines dans ces supports didactiques, publiés à 25 ans d’intervalle. La place des femmes a-t-elle changé durant ce laps de temps ? Comment sont-elles représentées ? Quelle place est donnée aux hommes ? Peut-on constater une égalité entre hommes et femmes dans certaines illustrations ? Pour tenter d’apporter des éléments de réponse à ces interrogations, ce travail propose une première analyse quantitative chiffrant le nombre de représentations féminines, masculines et mixtes dans ces différents ouvrages, suivie par une analyse qualitative se basant sur la manière dont les auteurs et autrices ont légendé et intégré les images.

description: In this extended note a critical discussion of an extension of the Lorentz transformations for velocities faster than the speed of light given recently by Hill and Cox is provided. The presented approach reveals the connection between faster-than-light speeds and the issue of isotropy of space. It is shown if the relative speed between the two inertial frames $v$ is greater than the speed of light, the condition of isotropy of space cannot be retained. It further specifies the respective transformations applying to $-\infty

Sharp interfaces in two dimensional free boundary problems: Efficient interface calculation via matched conformal maps

description: We use conformal maps to study a free boundary problem for a two-fluid electromechanical system, where the interface between the fluids is determined by the combined effects of electrostatic forces, gravity and surface tension. The free boundary in our system develops sharp corners/singularities in certain parameter regimes, and this is an impediment to using existing "single-scale" numerical conformal mapping methods. The difficulty is due to the phenomenon of crowding, i.e. the tendency of nodes in the preimage plane to concentrate near the sharp regions of the boundary, leaving the smooth regions of the boundary poorly resolved. A natural idea is to exploit the scale separation between the sharp regions and smooth regions to solve for each region separately, and then stitch the solutions together. However, this is not straightforward as conformal maps are rigid "global" objects, and it is not obvious how one would patch two conformal maps together to obtain a new conformal map. We develop a "multi-scale" (i.e. adaptive) conformal mapping method that allows us to carry out this program of stitching conformal maps on different scales together. We successfully apply our method to the electromechanical model problem and discuss how it generalizes to other situations.

description: Efficient implementations of parallel applications on heterogeneous hybrid architectures require a careful balance between computations and communications with accelerator devices. Even if most of the communication time can be overlapped by computations, it is essential to reduce the total volume of communicated data. The literature therefore abounds with ad-hoc methods to reach that balance, but that are architecture and application dependent. We propose here a generic mechanism to automatically optimize the scheduling between CPUs and GPUs, and compare two strategies within this mechanism: the classical Heterogeneous Earliest Finish Time (HEFT) algorithm and our new, parametrized, Distributed Affinity Dual Approximation algorithm (DADA), which consists in grouping the tasks by affinity before running a fast dual approximation. We ran experiments on a heterogeneous parallel machine with six CPU cores and eight NVIDIA Fermi GPUs. Three standard dense linear algebra kernels from the PLASMA library have been ported on top of the Xkaapi runtime. We report their performances. It results that HEFT and DADA perform well for various experimental conditions, but that DADA performs better for larger systems and number of GPUs, and, in most cases, generates much lower data transfers than HEFT to achieve the same performance.

description: The Kozai-Lidov mechanism can be applied to a vast variety of astrophysical systems involving hierarchical three-body systems. Here, we study the Kozai-Lidov mechanism systematically in the test particle limit at the octupole level of approximation. We investigate the chaotic and quasiperiodic orbital evolution by studying surfaces of section and the Lyapunov exponents. We find that the resonances introduced by the octupole level of approximation cause orbits to flip from prograde to retrograde and back as well as cause significant eccentricity excitation, and the chaotic behaviors occur when the mutual inclination between the inner and the outer binary is high. We characterize the parameter space that allows large amplitude oscillations in eccentricity and inclination.

description: We consider D7-branes probing several classes of Type IIB supergravity backgrounds, and study the classical problem of finding equilibrium configurations for the embedding functions. This is a method employed to model chiral symmetry breaking in the gravity dual of a strongly-coupled, confining gauge theory. We unveil and discuss a new type of phase transition appearing in the gravity systems, which is similar in nature and meaning to bulk phase transitions on the lattice. The existence of this genre of phase transition puts a new, intrinsic limit on the region of parameter space which can be used to study the physics of the dual field theory. We complete the analysis of D7 embeddings in wrapped-D5 supergravity backgrounds, and explain in what cases chiral-symmetry breaking is sensibly modelled by the gravity construction.

Constraints on the height of the inner disk rim in pre-main-sequence stars
Creators: name: Vinković, Dejan

Year: 2014
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: The structure of inner region of protoplanetary disks around young pre-main-sequence stars is still poorly understood. This part of the disk is shaped by various forces that influence dust and gas dynamics, and by dust sublimation, which creates abrupt drops in the dust density. This region also emits strong near-infrared excess that cannot be explained by classical accretion disk models, which suggests the existence of some unusual dust distribution or disk shape. The most prevalent explanation to date is the puffed-up inner disk rim model, where the disk exhibits an optically thin cavity around the star up to the distance of dust sublimation. The critical parameter in this model is the inner disk rim height $z_{\rm max}$ relative to the rim distance from the star $R_{\rm in}$. Observations often require $z_{\rm max}/R_{\rm in}\gtrsim0.2$ to reproduce the near-infrared excess in the spectra. We compile a comprehensive list of processes that can shape the inner disk rim and combine them into a self-consistent model. Two of them, radiation pressure force and the gas velocity profile, have never been applied in this context before. The aim was to find the most plausible theoretical values of $z_{\rm max}/R_{\rm in}$. The results show that this value is $\lesssim$0.13 for Herbig Ae stars, $\lesssim$0.11 for T Tau stars, and $\lesssim$0.10 for young brown dwarfs. This is lower than the observational requirements for Herbig Ae stars. We argue that the same problem exists in T Tau stars as well. We conclude that the puffed-up inner rim model cannot be the sole explanation for the near-infrared excess in young pre-main-sequence stars.

description: La relation entre l’enseignant et l’élève est le point central de cette recherche qui vise à mettre en évidence l’impact qu’a cette relation dans la réussite scolaire et l’estime de soi de l’élève. Parmi les aspects qui participent à la construction de l’image de soi de l’élève, j’ai essayé d’intégrer dans ma recherche les suivants aspects théoriques : l’effet Pygmalion, la motivation , l’évaluation et les conséquences de l’échec scolaire. L’effet Pygmalion (ou l’effet des attentes) participe à la construction de l’image de soi de l’élève car les attentes de l’enseignant influencent la performance scolaire de l’élève (Rosenthal et Jaco bson, 19 6 8). Un autre aspect important aux conséquences positives ou négatives sur l’estime de l’élè ve est l’évaluation : selon Chouinard (2002), des évaluations négatives répétées auront des conséquences négatives sur la motivation de l’élève dans son app rentissage. Enfin, le redoublement est aussi un autre aspect qui nuit à l’estime de soi de l’élève c ar par cet acte, il devient membre d’un groupe stigmatisé : celui des redoublants. Cette recherche qualitative vise également à mettre en évidence le parcou rs scolaire de certains élèves, en montrant qu’une bonne relation enseignant élève est très importan te dans la réussite scolaire de l’élève, pour sa motivation à aller à l’école, pour le climat de classe et finalement pour l’estime de l’élève. Ce dernier n ’est plus en échec car il se sent apprécié par l’enseignant. Pour analyser cette interaction entre é lève et enseignant, je me suis appuyée sur la notion de l’effet maître, exposée par Bressoux (2001), en essayant de montrer l’importance du rôle de l’enseig nant par rapport au jugement scolaire et comment ce jugement ait des conséquences pour le succès soc ial de l’élève. Cette recherche invite donc l’enseignant à s’interroger sur ses pratiques pédagogiques et à réfléchir à l’importance que les élèves confèren t à l’image de l’enseignant et à l’appréciation exprimée par ce dernier.

description: We present our astrometric observations of the small near-Earth object 2011~MD ($H \sim 28.0$), obtained after its very close fly-by to Earth in June 2011. Our set of observations extends the observational arc to $73$ days, and together with the published astrometry obtained around the Earth fly-by allows a direct detection of the effect of radiation pressure on the object, with a confidence of $5σ$. The detection can be used to put constraints on the density of the object, pointing to either an unexpectedly low value of $ρ= (640 \pm 330) \mbox{ kg} / \mbox{m} ^3$ ($68\%$ confidence interval) if we assume a typical probability distribution for the unknown albedo, or to an unusually high reflectivity of its surface. This result may have important implications both in terms of impact hazard from small objects and in light of a possible retrieval of this target.

description: We present the correlations between stellar mass, star formation rate (SFR) and [NII]/Ha flux ratio as indicator of gas-phase metallicity for a sample of 222 galaxies at 0.8 < z < 2.6 and log(M*/Msun)=9.0-11.5 from the LUCI, SINS/zC-SINF and KMOS3D surveys. This sample provides a unique analysis of the mass-metallicity relation (MZR) over an extended redshift range using consistent data analysis techniques and strong-line metallicity indicator. We find a constant slope at the low-mass end of the relation and can fully describe its redshift evolution through the evolution of the characteristic turnover mass where the relation begins to flatten at the asymptotic metallicity. At fixed mass and redshift, our data do not show a correlation between the [NII]/Ha ratio and SFR, which disagrees with the 0.2-0.3dex offset in [NII]/Ha predicted by the "fundamental relation" between stellar mass, SFR and metallicity discussed in recent literature. However, the overall evolution towards lower [NII]/Ha at earlier times does broadly agree with these predictions.

description: We report here how the hydration of complex surfaces can be efficiently studied thanks to recent advances in classical molecular density functional theory. This is illustrated on the example of the pyrophylite clay. After presenting the most recent advances, we show that the strength of this implicit method is that (i) it is in quantitative or semi-quantitative agreement with reference all-atoms simulations (molecular dynamics here) for both the solvation structure and energetics, and that (ii) the computational cost is two to three orders of magnitude less than in explicit methods. The method remains imperfect, in that it locally overestimates the polarization of water close to hydrophylic sites of the clay. The high numerical efficiency of the method is illustrated and exploited to carry a systematic study of the electrostatic and van der Waals components of the surface-solvant interactions within the most popular force field for clays, CLAYFF. Hydration structure and energetics are found to weakly depend upon the electrostatics. We conclude on the consequences of such findings in future force-field development.

Presentation

description: Project: Presentation - Contains presentations of different types published at the WDCC. Summary: Data maturity is an important topic in data management, which is reflected by a growing number of tools and theories trying to measure it. Data maturity describes the degree of the formalization/standardization of a data object with respect to FAIRness and quality of the (meta-)data. Currently, the DataCite Metadata Schema does not provide an explicit property to link/store information on data maturity (e.g. FAIRness or quality of data/metadata). The AtMoDat project team drafted an extension to the DataCite Metadata Schema to host such information. This extension is denoted as "Data Maturity Indicator".

description: We consider minimal extensions of the recently proposed Mimetic Dark Matter and show that by introducing a potential for the mimetic non-dynamical scalar field we can mimic nearly any gravitational properties of the normal matter. In particular, the mimetic matter can provide us with inflaton, quintessence and even can lead to a bouncing nonsingular universe. We also investigate the behaviour of cosmological perturbations due to a mimetic matter. We demonstrate that simple mimetic inflation can produce red-tilted scalar perturbations which are largely enhanced over gravity waves.

description: Realizing robust quantum information transfer between long-lived qubit registers is a key challenge for quantum information science and technology. Here we demonstrate unconditional teleportation of arbitrary quantum states between diamond spin qubits separated by 3 meters. We prepare the teleporter through photon-mediated heralded entanglement between two distant electron spins and subsequently encode the source qubit in a single nuclear spin. By realizing a fully deterministic Bell-state measurement combined with real-time feed-forward we achieve teleportation in each attempt while obtaining an average state fidelity exceeding the classical limit. These results establish diamond spin qubits as a prime candidate for the realization of quantum networks for quantum communication and network-based quantum computing.

description: The observation by Ke et al. [Science 338, 1177 (2012)] that large numbers of short, pre-designed DNA strands can assemble into three-dimensional target structures came as a great surprise, as no colloidal self-assembling system has ever achieved the same degree of complexity. That failure seemed easy to rationalise: the larger the number of distinct building blocks, the higher the expected error rate for self-assembly. The experiments of Ke et al. have disproved this argument. Here, we report Monte Carlo simulations of the self-assembly of a DNA brick cube, comprising approximately 1000 types of DNA strand, using a simple model. We model the DNA strands as lattice tetrahedra with attractive patches, the interaction strengths of which are computed using a standard thermodynamic model. We find that, within a narrow temperature window, the target structure assembles with high probability. Our simulations suggest that mis-assembly is disfavoured because of a slow nucleation step. As our model incorporates no aspect of DNA other than its binding properties, these simulations suggest that, with proper design of the building blocks, other systems, such as colloids, may also assemble into truly complex structures.

description: We combine the equations of motion that govern the dynamics of galaxies in the local volume with Bayesian techniques in order to fit orbits to published distances and velocities of galaxies within $\sim 3$ Mpc. We find a Local Group (LG) mass $2.3\pm 0.7\times 10^{12}{\rm M}_\odot$ that is consistent with the combined dynamical masses of M31 and the Milky Way, and a mass ratio $0.54^{+0.23}_{-0.17}$ that rules out models where our Galaxy is more massive than M31 with $\sim 95\%$ confidence. The Milky Way's circular velocity at the solar radius is relatively high, $245\pm 23$ km/s, which helps to reconcile the mass derived from the local Hubble flow with the larger value suggested by the `timing argument'. Adopting {\it Planck}'s bounds on $Ω_Λ$ yields a (local) Hubble constant $H_0=67\pm 5$km/s/Mpc which is consistent with the value found on cosmological scales. Restricted N-body experiments show that substructures tend to fall onto the LG along the Milky Way-M31 axis, where the quadrupole attraction is maximum. Tests against mock data indicate that neglecting this effect slightly overestimates the LG mass without biasing the rest of model parameters. We also show that both the time-dependence of the LG potential and the cosmological constant have little impact on the observed local Hubble flow.
description: 22 pages, 14 figures. Accepted to MNRAS. An error in the apex calculation (Appendix A) was found and has been fixed. The new constraints favour models where the Milky Way is less massive than M31. The rest of model parameters and conclusions remain unchanged

description: Durant nos pratiques professionnelles en enseignement, nous avons relevé une apparente démotivation chez les élèves rencontrant des difficultés en mathématiques qui se confirme dans de nombreuses études (Chouinard, 2001 ; Chouinard & Roy, 2008 ; Gurtner et al., 2009 ; Jacobs et al., 2002 ; Leblond, 2012 ; Watt, 2004). Sachant que la motivation est fortement liée à la réussite de l’apprentissage (Chouinard, 2001), il s’avère qu’un des facteurs importants pour pallier, du moins partiellement, à ce constat se situe au niveau du sentiment d’efficacité personnelle, une composante importante de la dynamique motivationnelle, qui correspond à la croyance personnelle en ses propres capacités à réussir dans un domaine ou une tâche précise. Par conséquent, il nous semble important d’étudier l’évolution du sentiment d’efficacité personnelle dans les différents domaines mathématiques au cycle secondaire car un tel travail pourrait fournir des informations utiles à la réflexion sur l’enseignement des mathématiques. Dans cette étude, nous avons essayé de cerner l’évolution du sentiment d’efficacité personnelle lors d’une séquence d’enseignement sur les grandeurs et mesures dans une classe de 11H niveau 1 au moyen d’un questionnaire liée à une tâche spécifique effectuée par les élèves. L’analyse des résultats indique une augmentation contenue du sentiment d’efficacité personnelle qui s’expliquerait principalement, selon nous, par les connaissances emmagasinées et par des feedbacks positifs centrés sur le travail de l’élève. Par ailleurs, des différences de sentiment d’efficacité personnelle entre filles et garçons apparaissent et pourraient s’expliquer par différents facteurs tels que les expériences familiales et sociétales liées aux stéréotypes, ainsi que le comportement différenciée des enseignants – interactions, attentes et feedbacks différents selon le genre de l’élève. De plus, ces différences de sentiment d’efficacité personnelle ne semblent pas varier sur la séquence, ce qui pourrait signifier que les messages stéréotypés affecteraient autant les garçons que les filles (Watt, 2004). Enfin, nous proposons également une analyse de quelques dimensions retenues pour l’étude afin de mieux comprendre les résultats relatifs à l’évolution du sentiment d’efficacité personnelle.
Effect of nonmagnetic dilution in honeycomb lattice iridates Na$_2$IrO$_3$ and Li$_2$IrO$_3$

description: We have synthesized single crystals of Na$_2$(Ir$_{1-x}$Ti$_x$)O$_3$ and polycrystals of Li$_2$(Ir$_{1-x}$Ti$_x$)O$_3$ and studied the effect of magnetic depletion on the magnetic properties by measurements of the magnetic susceptibility, specific heat and magnetocaloric effect at temperatures down to 0.1~K. In both systems, the non-magnetic substitution rapidly changes the magnetically ordered ground state into a spin glass, indicating strong frustration. While for the Li system the Weiss temperature $Θ_{\rm W}$ remains unchanged up to $x=0.55$, a strong decrease $|Θ_{\rm W}|$ is found for the Na system. This suggests that only for the former system magnetic exchange beyond nearest neighbors is dominating. This is also corroborated by the observation of a smeared quantum phase transition in Li$_2$(Ir$_{1-x}$Ti$_x$)O$_3$ near $x=0.5$, i.e. much beyond the site percolation threshold of the honeycomb lattice.

description: Skyrmions of different dimensions are related by domain walls. We obtain explicit full numerical solutions of various Skyrmion configurations trapped inside a domain wall. We find for the quadratic mass-term that multi-Skyrmions are ring-shaped, and conjecture for the linear mass-term, that the lowest-energy state of multi-Skyrmions will consist of charge-2 rings accommodated in a lattice.

description: Recent observations suggest that some high-velocity clouds may be confined by massive dark matter halos. In particular, the proximity and proposed dark matter content of the Smith Cloud make it a tempting target for the indirect detection of dark matter annihilation. We argue that the Smith Cloud may be a better target than some Milky Way dwarf spheroidal satellite galaxies and use gamma-ray observations from the Fermi Large Area Telescope to search for a dark matter annihilation signal. No significant gamma-ray excess is found coincident with the Smith Cloud, and we set strong limits on the dark matter annihilation cross section assuming a spatially-extended dark matter profile consistent with dynamical modeling of the Smith Cloud. Notably, these limits exclude the canonical thermal relic cross section ($\sim 3\times10^{-26}{\rm cm}^{3}{\rm s}^{-1}$) for dark matter masses $\lesssim 30$ GeV annihilating via the $b \bar b$ or $τ^{+}τ^{-}$ channels for certain assumptions of the dark matter density profile; however, uncertainties in the dark matter content of the Smith Cloud may significantly weaken these constraints.

Lattice QCD with mismatched Fermi surfaces

description: We study two flavor fermions with mismatched chemical potentials in quenched lattice QCD. We first consider a large isospin chemical potential, where a charged pion is condensed, and then introduce a small mismatch between the chemical potentials of the up quark and the anti-down quark. We find that the homogeneous pion condensate is destroyed by the mismatch of the chemical potentials. We also find that the two-point correlation function shows spatial oscillation, which indicates an inhomogeneous ground state, although it is not massless but massive in the present simulation setup.

description: Community detection is an important task in network analysis, in which we aim to learn a network partition that groups together vertices with similar community-level connectivity patterns. By finding such groups of vertices with similar structural roles, we extract a compact representation of the network's large-scale structure, which can facilitate its scientific interpretation and the prediction of unknown or future interactions. Popular approaches, including the stochastic block model, assume edges are unweighted, which limits their utility by throwing away potentially useful information. We introduce the `weighted stochastic block model' (WSBM), which generalizes the stochastic block model to networks with edge weights drawn from any exponential family distribution. This model learns from both the presence and weight of edges, allowing it to discover structure that would otherwise be hidden when weights are discarded or thresholded. We describe a Bayesian variational algorithm for efficiently approximating this model's posterior distribution over latent block structures. We then evaluate the WSBM's performance on both edge-existence and edge-weight prediction tasks for a set of real-world weighted networks. In all cases, the WSBM performs as well or better than the best alternatives on these tasks.
