description: We have studied low-temperature properties of interacting electrons in a one-dimensional quantum wire (Luttinger liquid) side-hybridized with a single-level impurity. The hybridization induces a back-scattering of electrons in the wire which strongly affects its low energy properties. Using a one-loop renormalization group approach valid for a weak electron-electron interaction, we have calculated a transmission coefficient through the wire, $\mathcal{T}(\varepsilon)$, and a local density of states, $ν(\varepsilon)$ at low energies $\varepsilon $. In particular, we have found that the antiresonance in $\mathcal{T}(\varepsilon)$ has a generalized Breit-Wigner shape with the effective width $Γ(\varepsilon)$ which diverges at the Fermi level.

description: Dopo l’apertura delle scuole pubbliche avvenuta con la legge n. 517 /1977, il sordoè entrato a far parte della società acustica di tipo verbale in cui le comunicazioni sonoper lo più di massa, pertanto ha incontrato notevoli difficoltà in parte oggi diminuitegrazie alle avanzate tecnologie computerizzate. Nonostante tali progressi manca unprogramma di base per gli operatori socio-assistenziali specializzati per l’aiutopersonale, ad esempio gli assistenti alla comunicazione, gli educatori sordi, gliinterpreti della lingua dei segni, ecc.; anzi, si continua a sollecitare ed a fornire risorsesolo per la riabilitazione acustica o logopedia. Questo significa non vedere il problemadella sordità o volerlo risolvere solo in parte o in modo superficiale. Al contrariobisogna ridare dignità alle persone sorde e alle loro famiglie, rendendo più facile illoro inserimento nella società e il primo passo da compiere è quello di utilizzare tuttele metodologie più consone e più efficaci in modo da farle essere autonome; tra questemetodologie vi è la logogenia. Questa nuova metodologia ha la caratteristica di poteressere attuata indipendentemente dal fatto che il sordo sia oralista o segnante, perchélo scopo, attuato attraverso la scrittura, è di chiarire quelle strutture grammaticalisintattiche, fondamentali alla comprensione del testo, che non vengono mai benspiegate ed assimilate dai sordi, determinando una scarsa comprensione dei messaggicomunicativi che gli emittenti indirizzano loro. In conclusione il sordo può divenirepadrone del linguaggio lavorando sullo stesso, evincendo da solo le rispettive funzionidelle parti del discorso.

description: We investigate the influence of Toomre's $Q$ parameter on the bar-forming dynamics of Maclaurin disk using $N$-body simulations. According to the Toomre's criterion, local velocity dispersion parametrized by $Q\geq 1$ is required to suppress the local axisymmetric instability but, in turn, it deviates particle orbits from nearly circular limit in which particle natural frequencies are calculated. We resolve this by including the effect of velocity dispersion, as the pressure potential, into the effective potential with the gravitational potential. With this formulation, circular orbit approximation is retrieved. The effective potential hypothesis can describe the $Q$-dependences of angular and epicyclic motions of the bar-forming processes and the established bars reasonably well provided that $Q\geq 1$. This indicates the influence of initial $Q$ that is imprinted in the entire disk dynamics, not only that $Q$ serves as the stability indicator. In addition, we perform the stability test for the disk-in-halo systems. With the presence of halo, disks are more susceptible to the bar formation as seen by the elevated critical $Q$ than that for the isolated disk. This is attributed to the differential rotation that builds the unstable non-axisymmetric spiral modes more efficiently which are the ingredients of bar instability.

description: We study the Dirichlet problem for the stationary Schrödinger fractional Laplacian equation $(-Δ)^s u + V u = f$ posed in bounded domain $ Ω\subset \mathbb R^n$ with zero outside conditions. We consider general nonnegative potentials $V\in L^1_{loc}(Ω)$ and prove well-posedness of very weak solutions when the data are chosen in an optimal class of weighted integrable functions $f$. Important properties of the solutions, such as its boundary behaviour, are derived. The case of super singular potentials that blow up near the boundary is given special consideration.

description: Il mondo della sordità viene anche chiamato “città invisibile”; noi udenti non ci accorgiamose una persona è sorda o meno, finché non la vediamo usare la Lingua dei Segni. Solo inquel momento preciso ci rendiamo conto che la sordità in sé e per sé è totalmente spiazzante,proprio perché è “invisibile”, a differenza di un qualsiasi altro tipo di handicap fisico: nonsiamo in grado di “prepararci” alla sordità. La ricercatrice Simonetta Maragna definisce lasordità “un handicap nascosto”1, poiché le sue problematiche non sono facilmente e immediatamenteindividuabili dagli udenti e da tutti coloro che sono estranei a questo mondo.Perché di mondo si tratta. Quello dei sordi è un mondo con una propria storia ed una propriacultura che ha origini in un’epoca a noi lontana. Il centro gravitazionale attorno a cuiruota l’universo dei sordi è la Lingua dei Segni, ovvero il più diretto, naturale e visivo mezzodi comunicazione che le persone sorde usano per esprimersi. La Lingua dei Segni èl’elemento essenziale per far sì che si crei una comunità sorda. Costituisce l’aggregazionebasilare e il riconoscimento dei sordi, la consapevolezza della propria identità e del proprio“esserci”2, attraverso l’espressione del canale visivo-gestuale.

description: We develop the formal theory of monads, as established by Street, in univalent foundations. This allows us to formally reason about various kinds of monads on the right level of abstraction. In particular, we define the bicategory of monads internal to a bicategory, and prove that it is univalent. We also define Eilenberg-Moore objects, and we show that both Eilenberg-Moore categories and Kleisli categories give rise to Eilenberg-Moore objects. Finally, we relate monads and adjunctions in arbitrary bicategories. Our work is formalized in Coq using the UniMath library.

description: L’analisi delle ricerche condotte sullo sviluppo del linguaggio di bambini udenti e sordimostrano che nel primo anno di vita esiste una completa equipotenzialità: la facoltà dilinguaggio che caratterizza la specie umana può manifestarsi in entrambe le modalitàacustico-vocale o visivo-gestuale; la scelta di una o dell’altra dipende dall’input linguistico acui è esposto il bambino. Risulta evidente che la lingua orale non può essere la prima linguaper il bambino che nasce sordo o lo diventa nei primi anni di vita: non potendo udire, nonriesce ad acquisire il linguaggio parlato nei tempi e nei modi in cui questo avviene neibambini udenti. Se esposto ad una lingua dei segni, invece, la acquisisce con la stessa facilitàe secondo le stesse tappe seguite dai bambini udenti nell’acquisizione della lingua parlata.Questo dimostra che la sua facoltà di linguaggio, così come le sue capacità cognitive, sonoperfettamente integre. Al contrario, per poter apprendere il linguaggio vocale, il bambinosordo necessita di un addestramento specifico che dura molti anni. La prima lingua è frutto diacquisizione, non di apprendimento: può emergere solo in condizioni naturali e spontaneema, nonostante ciò, il bambino sordo difficilmente si trova ad aver acquisito, secondo tempi eritmi naturali, l’unica lingua a lui pienamente accessibile: la lingua dei segni.

description: We report transport properties of single-crystalline Pd$_{3}$Bi$_{2}$S$_{2}$, which has been predicted to host an unconventional electronic phase of matter beyond three-dimensional Dirac and Weyl semimetals. Similar to several topological systems, the resistivity shows field induced metal-semiconductor-like crossover at low temperature. Large, anisotropic and non-saturating magnetoresistance (MR) has been observed in transverse experimental configuration. At 2 K and 9 T, the MR value reaches as high as $\sim$1.1$\times$10$^{3}$ \%. Hall resistivity reveals the presence of two types of charge carriers and has been analyzed using two-band model. In spite of the large density ($>$ 10$^{21}$ cm$^{-3}$), the mobility of charge carriers is found to be quite high ($\sim$ 0.75$\times$10$^{4}$ cm$^{2}$ V$^{-1}$ s$^{-1}$ for hole and $\sim$ 0.3$\times$10$^{4}$ cm$^{2}$ V$^{-1}$ s$^{-1}$ for electron). The observed magneto-electrical properties indicate that Pd$_{3}$Bi$_{2}$S$_{2}$ may be a new member of the topological semimetal family, which can have a significant impact in technological applications.

description: We re\,examine the theory of hadronic photon-nucleon interactions at the quark-gluon level. The possibility of multiple parton collisions in a single photon-nucleon collision requires an eikonal treatment of the high-energy scattering process. We give a general formulation of the theory in which the $γp$ cross section is expressed as a sum over properly eikonalized cross sections for the interaction of the virtual hadronic components of the photon with the proton, with each cross section weighted by the probability with which that component appears in the photon, and then develop a detailed model which includes contributions from light vector mesons and from excited virtual states described in a quark-gluon basis. The parton distribution functions which appear can be related approximately to those in the pion, while a weighted sum gives the distribution functions for the photon. We use the model to make improved QCD-based predictions for the total inelastic photon-nucleon and photon-nucleus cross sections at energies relevant for HERA experiments and cosmic ray observations. We emphasize the importance in this procedure of including a soft-scattering background such that the calculated cross sections join smoothly with low-energy data.

description: Unlike general relativity, in bimetric gravity linear gravitational waves do not evolve as free fields. In this theory there are two types of tensor perturbations, whose interactions are inherited from non-trivial couplings between two dynamical metric tensor fields in the Hassan-Rosen action, and are responsible for the phenomenon of bigravity oscillations. In this work, we analyze the dynamics of cosmological tensor modes in bimetric gravity on sub-horizon scales and close to the general relativity limit. In this limit, the system has a characteristic length scale $L$ that is strictly contained within the comoving Hubble radius. Thus, depending on the magnitude of the comoving wavelength $λ$ relative to $L$, we identify two regimes of interest where the system can be studied analytically: (i) deep sub-horizon modes with $λ\ll L$, whose dynamics can be studied using multiple scale analysis and are characterized by small and slowly evolving super-imposed perturbations; (ii) sub-horizon modes with $λ\gg L$, where the dynamics is characterized by fast super-imposed oscillations that can be studied using asymptotic techniques for highly oscillatory problems. Furthermore, our analysis represents a substantial improvement compared to previous analyses based on a generalization of the WKB method, which, as we show, is ill-suited to study the system at hand.

The double-diversity $γ_2(\mathcal{F})$ is defined as the minimum of $|\mathcal{F}(\bar{x},\bar{y})|$ over all pairs $x,y$. Let $\mathcal{L}\subset\binom{[7]}{3}$ consist of the seven lines of the Fano plane. For $n\geq 7$, $k\geq 3$ one defines the Fano $k$-graph $\mathcal{F}_{\mathcal{L}}$ as the collection of all $k$-subsets of $[n]$ that contain at least one line. It is proven that for $n\geq 13k^2$ the Fano $k$-graph is the essentially unique family maximizing the double diversity over all $k$-graphs without a pair of disjoint edges. Some similar, although less exact results are proven for triple and higher diversity as well.

description: Data analysis often involves the comparison of complex objects. With the ever increasing amounts and complexity of data, the demand for systems to help with these comparisons is also growing. Increasingly, information visualization tools support such comparisons explicitly, beyond simply allowing a viewer to examine each object individually. In this paper, we argue that the design of information visualizations of complex objects can, and should, be studied in general, that is independently of what those objects are. As a first step in developing this general understanding of comparison, we propose a general taxonomy of visual designs for comparison that groups designs into three basic categories, which can be combined. To clarify the taxonomy and validate its completeness, we provide a survey of work in information visualization related to comparison. Although we find a great diversity of systems and approaches, we see that all designs are assembled from the building blocks of juxtaposition, superposition and explicit encodings. This initial exploration shows the power of our model, and suggests future challenges in developing a general understanding of comparative visualization and facilitating the development of more comparative visualization tools.

description: La LIS è la lingua naturale dei sordi. Essa svolge una funzione sociale: favorisce, cioè,lo sviluppo cognitivo e relazionale nelle persone sorde, poiché le sue principali componentigrammaticali e sintattiche rispondono alle loro reali esigenze cognitive e sensoriali. Si puòdire, infatti, che la mano del sordo corrisponde alla lingua fisiologica dell’udente, ma ciò nonvuol dire che il sordo sia privo della parola: il suo apparato fono-articolatorio è integro.Semplicemente la non conoscenza profonda dei codici vocali deriva dalla carenza delcosiddetto “bagno sonoro” piagetiano.1 Infatti, la differenza tra lo sviluppo del linguaggionel bambino sordo rispetto al bambino udente, diventa tangibile intorno al primo anno divita, poiché il bambino sordo riscontra difficoltà a imitare i suoni e le parole che gli udentiintorno a lui utilizzano. Per questo è importante che il bambino sordo sia esposto alla LIS giàdalle prime tappe dello sviluppo sensomotorio: in tal modo il bambino acquisisce la LIS inmodo spontaneo e naturale e, una volta acquisita la competenza linguistica nella primalingua, potrà facilmente trasferire e applicare le regole che sottostanno a essa,all’apprendimento della seconda lingua, l’italiano. Questo avviene più facilmente se nellarieducazione al linguaggio del bambino sordo viene adottato il metodo bilingue: il piùefficace e il più gradito agli alunni sordi stessi, poiché maggiormente rispettoso diquell’″anima sorda″ e di quella identità verace sorda che spesso viene calpestata e repressa.

Confinement- and strain-induced enhancement of thermoelectric properties in LaNiO$_3$/LaAlO$_3(001)$ superlattices

description: By combining ab initio simulations including an on-site Coulomb repulsion term and Boltzmann theory, we explore the thermoelectric properties of (LaNiO$_3$)$_n$/(LaAlO$_3$)$_n$(001) superlattices ($n=1,3$) and identify a strong dependence on confinement, spacer thickness, and epitaxial strain. While the system with $n=3$ shows modest values of the Seebeck coefficient and power factor, the simultaneous reduction of the LaNiO$_3$ region and the LaAlO$_3$ spacer thickness to single layers results in a strong enhancement, in particular of the in-plane values. This effect can be further tuned by using epitaxial strain as control parameter: Under tensile strain corresponding to the lateral lattice constant of SrTiO$_3$ we predict in- and cross-plane Seebeck coefficients of $\pm 600$ $μ$V/K and an in-plane power factor of $11$ $μ$W/K$^2$cm for an estimated relaxation time of $τ= 4$ fs around room temperature. These values are comparable to some of the best performing oxide systems such as La-doped SrTiO$_3$ or layered cobaltates and are associated with the opening of a small gap ($0.29$ eV) induced by the concomitant effect of octahedral tilting and Ni-site disproportionation. This establishes oxide superlattices at the verge of a metal-to-insulator transition driven by confinement and strain as promising candidates for thermoelectric materials.

description: In this study, we propose a test for the coefficient randomness in autoregressive models where the autoregressive coefficient is local to unity, which is empirically relevant given the results of earlier studies. Under this specification, we theoretically analyze the effect of the correlation between the random coefficient and disturbance on tests' properties, which remains largely unexplored in the literature. Our analysis reveals that the correlation crucially affects the power of tests for coefficient randomness and that tests proposed by earlier studies can perform poorly when the degree of the correlation is moderate to large. The test we propose in this paper is designed to have a power function robust to the correlation. Because the asymptotic null distribution of our test statistic depends on the correlation $ψ$ between the disturbance and its square as earlier tests do, we also propose a modified version of the test statistic such that its asymptotic null distribution is free from the nuisance parameter $ψ$. The modified test is shown to have better power properties than existing ones in large and finite samples.

description: We present the general theory of clean, two-dimensional, quantum Heisenberg antiferromagnets which are close to the zero-temperature quantum transition between ground states with and without long-range Néel order. For Néel-ordered states, `nearly-critical' means that the ground state spin-stiffness, $ρ_s$, satisfies $ρ_s \ll J$, where $J$ is the nearest-neighbor exchange constant, while `nearly-critical' quantum-disordered ground states have a energy-gap, $Δ$, towards excitations with spin-1, which satisfies $Δ\ll J$. Under these circumstances, we show that the wavevector/frequency-dependent uniform and staggered spin susceptibilities, and the specific heat, are completely universal functions of just three thermodynamic parameters. Explicit results for the universal scaling functions are obtained by a $1/N$ expansion on the $O(N)$ quantum non-linear sigma model, and by Monte Carlo simulations. These calculations lead to a variety of testable predictions for neutron scattering, NMR, and magnetization measurements. Our results are in good agreement with a number of numerical simulations and experiments on undoped and lightly-doped $La_{2-δ} Sr_δCu O_4$.

description: La sordità potrebbe non essere un handicap, se non fosse per il fatto che viviamo in unasocietà verbale, sviluppatasi, su relazioni e modalità di comprensione della realtà cheimplicano l’uso del codice linguistico fonico-vocale. Gli stessi processi d’insegnamento sonofondati sul Know-that, la descrizione verbale delle modalità di esecuzione di un compito,piuttosto che sul Know-how, la capacità di eseguirlo. A farne le spese, i sordi che, a quasivent’anni dall’approvazione della L. 104/92 che ne formalizzava l’ingresso a scuola, vedonola loro integrazione un processo, sia sul piano affettivo sia su quello cognitivo, tutto inperdita. Ma la ricerca di percorsi educativi capaci di rispondere alle esigenze del sordo,implica la ricerca delle finalità da cui partire, perché in pedagogia sono proprio queste chedeterminano modalità e metodologie. E il concetto di felicità, proposto dalla teoria della“Creazione di valore” di Machiguki, può rivelarsi un utile contributo per riuscire acomprendere che la scuola, per essere veramente inclusiva, deve accettare l’idea delbilinguismo LIS/Italiano, come presupposto metodologico da cui partire. Perché l’uso dellaLIS a scuola ci permette non solo di rompere l’isolamento cui sono condannati i sordi, maanche di favorirne l’apprendimento. L’integrazione diviene inclusiva quando trasforma lascuola in una comunità educante dove tutti possono esprimere ed accrescere le propriepotenzialità senza il timore di essere giudicati.

description: Spontaneous symmetry breaking-the phenomenon where an infinitesimal perturbation can cause the system to break the underlying symmetry-is a cornerstone concept in the understanding of interacting solid-state systems. In a typical series of temperature-driven phase transitions, higher temperature phases are more symmetric due to the stabilizing effect of entropy that becomes dominant as the temperature is increased. However, the opposite is rare but possible when there are multiple degrees of freedom in the system. Here, we present such an example of a symmetry-ascending phenomenon in a magnetic kagome metal FeGe by utilizing neutron Larmor diffraction and Raman spectroscopy. In the paramagnetic state at 460K, we confirm that the crystal structure is indeed hexagonal kagome lattice. On cooling to TN, the crystal structure changes from hexagonal to monoclinic with in-plane lattice distortions on the order of 10^(-4) and the associated splitting of the double degenerate phonon mode of the pristine kagome lattice. Upon further cooling to TCDW, the kagome lattice shows a small negative thermal expansion, and the crystal structure becomes more symmetric gradually upon further cooling. Increasing the crystalline symmetry upon cooling is unusual, it originates from an extremely weak structural instability that coexists and competes with the CDW and magnetic orders. These observations are against the expectations for a simple model with a single order parameter, hence can only be explained by a Landau free energy expansion that takes into account multiple lattice, charge, and spin degrees of freedom. Thus, the determination of the crystalline lattice symmetry as well as the unusual spin-lattice coupling is a first step towards understanding the rich electronic and magnetic properties of the system and sheds new light on intertwined orders where the lattice degree of freedom is no longer dominant.

description: We perform a three-dimensional triaxial analysis of 16 X-ray regular and 4 high-magnification galaxy clusters selected from the CLASH survey by combining two-dimensional weak-lensing and central strong-lensing constraints. In a Bayesian framework, we constrain the intrinsic structure and geometry of each individual cluster assuming a triaxial Navarro-Frenk-White halo with arbitrary orientations, characterized by the mass $M_{200\mathrm{c}}$, halo concentration $C_{200\mathrm{c}}$, and triaxial axis ratios ($q_{\mathrm{a}} \le q_{\mathrm{b}}$), and investigate scaling relations between these halo structural parameters. From triaxial modeling of the X-ray-selected subsample, we find that the halo concentration decreases with increasing cluster mass, with a mean concentration of $C_{200\mathrm{c}} = 4.82\pm0.30$ at the pivot mass $M_{200\mathrm{c}}=10^{15}M_{\odot}h^{-1}$. This is consistent with the result from spherical modeling, $C_{200\mathrm{c}}=4.51\pm 0.14$. Independently of the priors, the minor-to-major axis ratio $q_{\mathrm{a}}$ of our full sample exhibits a clear deviation from the spherical configuration ($q_{\mathrm{a}}=0.52 \pm 0.04$ at $10^{15}M_{\odot}h^{-1}$ with uniform priors), with a weak dependence on the cluster mass. Combining all 20 clusters, we obtain a joint ensemble constraint on the minor-to-major axis ratio of $q_{\mathrm{a}}=0.652^{+0.162}_{-0.078}$ and a lower bound on the intermediate-to-major axis ratio of $q_{\mathrm{b}}>0.63$ at the $2σ$ level from an analysis with uniform priors. Assuming priors on the axis ratios derived from numerical simulations, we constrain the degree of triaxiality for the full sample to be $\mathcal{T}=0.79 \pm 0.03$ at $10^{15}M_{\odot}h^{-1}$, indicating a preference for a prolate geometry of cluster halos. We find no statistical evidence for an orientation bias ($f_{\mathrm{geo}}=0.93 \pm 0.07$) (abridged)

description: The aim of this article is to extend the scope of the theory of regularity structures in order to deal with a large class of singular SPDEs of the form $$\partial_t u = \mathfrak{L} u+ F(u, ξ)\ ,$$ where the differential operator $\mathfrak{L}$ fails to be elliptic. This is achieved by interpreting the base space $\mathbb{R}^{d}$ as a non-trivial homogeneous Lie group $\mathbb{G}$ such that the differential operator $\partial_t -\mathfrak{L}$ becomes a translation invariant hypoelliptic operator on $\mathbb{G}$. Prime examples are the kinetic Fokker-Planck operator $\partial_t -Δ_v - v\cdot \nabla_x$ and heat-type operators associated to sub-Laplacians. As an application of the developed framework, we solve a class of parabolic Anderson type equations $$\partial_t u = \sum_{i} X^2_i u + u (ξ-c)$$ on the compact quotient of an arbitrary Carnot group.

description: We ask the question of classical super (non-)Abelian T-duality for BTZ black hole metric coupling to two fermionic fields. Our approach is based on super Poisson-Lie (PL) T-duality in the presence of spectator fields. In order to study the Abelian T-duality of the metric we dualize over the Abelian Lie supergroups of the types $(1|2)$ and $(2|2)$, in such a way that it is shown that both original and dual backgrounds of the models are conformally invariant up to one-loop order in the presence of field strength. Then, we study the non-Abelian T-duality of the BTZ vacuum metric coupling to two fermionic fields. The dualizing is performed on some non-Abelian Lie supergroups of the type $(2|2)$, in such a way that we are dealing with semi-Abelian superdoubles which are non-isomorphic as Lie superalgebras in each of the models. In the non-Abelian T-duality case, it is interesting to mention that the models can be conformally invariant up to one-loop order in both cases of the absence and presence of field strength. In addition, starting from the decomposition of semi-Abelian Drinfeld superdoubles generated by some of the ${\cal C}^3 \oplus {\cal A}_{1,1}$ Lie superbialgebras we study the super PL T-plurality of the BTZ vacuum metric coupled to two fermionic fields. However, our findings are interesting in themselves, but at a constructive level, can prompt many new insights into supergravity and manifestly have interesting mathematical relationships with double field theory.

A Simple Algorithm for Consistent Query Answering under Primary Keys

description: We consider the dichotomy conjecture for consistent query answering under primary key constraints. It states that, for every fixed Boolean conjunctive query q, testing whether q is certain (i.e. whether it evaluates to true over all repairs of a given inconsistent database) is either polynomial time or coNP-complete. This conjecture has been verified for self-join-free and path queries.
 We propose a simple inflationary fixpoint algorithm for consistent query answering which, for a given database, naively computes a set $Δ$ of subsets of facts of the database of size at most k, where k is the size of the query q. The algorithm runs in polynomial time and can be formally defined as: (1) Initialize $Δ$ with all sets $S$ of at most $k$ facts such that $S\models q$. (2) Add any set $S$ of at most k facts to $Δ$ if there exists a block $B$ (i.e., a maximal set of facts sharing the same key) such that for every fact $a \in B$ there is a set $S' \subseteq S \cup \{a\}$ such that $S'\in Δ$.
 For an input database $D$, the algorithm answers "q is certain" iff $Δ$ eventually contains the empty set. The algorithm correctly computes certainty when the query q falls in the polynomial time cases of the known dichotomies for self-join-free queries and path queries. For arbitrary Boolean conjunctive queries, the algorithm is an under-approximation: the query is guaranteed to be certain if the algorithm claims so. However, there are polynomial time certain queries (with self-joins) which are not identified as such by the algorithm.
Five ways to recover the symbol of a non-binary localization operator

description: Five constructive methods for recovering the symbol of a time-frequency localization operator with non-binary symbol are presented, two based on earlier work and three novel methods. For the two derivative methods which have previously been applied to binary symbols, we propose a changed symbol estimator and provide additional estimates that show how we can recover non-binary symbols. The three novel methods each have their own advantages and are all applicable to non-binary symbols. Two of them rely on prescribing the input of the localization operator and examining the output, allowing for targeting of the part of the symbol one wishes to recover while the last one relies on spectral information about the operator. All five methods are also implemented numerically and evaluated with the code available.

description: Particles in a curved space are classically described by a nonlinear sigma model action that can be quantized through path integrals. The latter require a precise regularization to deal with the derivative interactions arising from the nonlinear kinetic term. Recently, for maximally symmetric spaces, simplified path integrals have been developed: they allow to trade the nonlinear kinetic term with a purely quadratic kinetic term (linear sigma model). This happens at the expense of introducing a suitable effective scalar potential, which contains the information on the curvature of the space. The simplified path integral provides a sensible gain in the efficiency of perturbative calculations. Here we extend the construction to models with N = 1 supersymmetry on the worldline, which are applicable to the first quantized description of a Dirac fermion. As an application we use the simplified worldline path integral to compute the type-A trace anomaly of a Dirac fermion in d dimensions up to d = 16.

Streaming instability in neutron star magnetospheres: No indication of soliton-like waves

description: Coherent radiation of pulsars, magnetars, and fast radio bursts could, in theory, be interpreted as radiation from solitons and soliton-like waves. The solitons are meant to contain a large number of electric charges confined on long time-scales and may radiate strongly by coherent curvature emission. However, solitons are also known to undergo a wave collapse, which may cast doubts on the correctness of the soliton radio emission models of neutron stars.
 We investigate the evolution of the caviton type of solitons self-consistently formed by the relativistic streaming instability and compare their apparent stability in 1D calculations with more generic 2D cases, in which the solitons are seen to collapse. Three representative cases of beam Lorentz factors and plasma temperatures are studied to obtain soliton dispersion properties. We utilized 1D electrostatic and 2D electromagnetic relativistic particle-in-cell simulations at kinetic microscales.
 We found that no solitons are generated by the streaming instability in the 2D simulations. Only superluminal L-mode (relativistic Langmuir) waves are produced during the saturation of the instability, but these waves have smaller amplitudes than the waves in the 1D simulations. The amplitudes tend to decrease after the instability has saturated, and only waves close to the light line, $ω= c k$, remain. Solitons in the 1D approach are stable for $γ_\mathrm{b} \gtrsim 60$, but they disappear for low beam Lorentz factor $γ_\mathrm{b} < 6$.
 Our examples show that the superluminal soliton branch that is formed in 1D simulations will not be generated by the relativistic streaming instability when more dimensional degrees of freedom are present - unless one can show that there are alternative plasma mechanisms for the soliton generation.

Spontaneous Baryogenesis in Supersymmetric Models

description: In this paper we extend the results of previous work on spontaneous baryogenesis to general models involving CP violation in the Higgs sector. We show how to deal with Chern-Simons terms appearing in the effective potential arising from phase changes in the vacuum expectation values of the Higgs fields. In particular, this enables us to apply this mechanism to general supersymmetric models including the minimal supersymmetric standard model, and the extended model with a gauge singlet. A comparison is made between this approach, and that in which one solves the equations of motion for Higgs winding modes. As anticipated in earlier work, the effect of the latter approach is found to be small.

description: We consider the Witten-Sakai-Sugimoto model in the approximation of smeared instantons at finite density via a homogeneous Ansatz, which is known to be discontinuous in order to be able to contain a nonvanishing baryon density. The discontinuity at the infrared tip of the bulk spacetime gives rise to subtleties of discarding boundary terms that are normally discarded in the literature. We propose a reason for discarding this boundary term, by scrutinizing the currents and topological properties of the model. Along the way, we find a very effective and simple condition to compute the point of thermodynamic equilibrium.
