description: We prove a result on the fractional Sobolev regularity of composition of paths of low fractional Sobolev regularity with functions of bounded variation. The result relies on the notion of variability, proposed by us in the previous article [43, arXiv:2003.11698]. Here we work under relaxed hypotheses, formulated in terms of Sobolev norms, and we can allow discontinuous paths, which is new. The result applies to typical realizations of certain Gaussian or Lévy processes, and we use it to show the existence of Stieltjes type integrals involving compositions.

description: The engineering of non-trivial topology in superconducting heterostructures is a very challenging task. Reducing the number of components in the system would facilitate the creation of the long-sought Majorana bound states. Here, we explore a route toward emergent topology in a trivial superconductor without a need for other proximitized materials. Specifically, we show that a vortex hosting an even number of flux quanta is capable of forming a quasi-one-dimensional topological sub-system that can be mapped to the Kitaev wire, if the vortex is trapped at a screw dislocation. This crystallographic defect breaks inversion symmetry and thereby threads a local spin-orbit coupling through the superconductor. The vortex-dislocation pair in the otherwise trivial bulk can harbor a pair of Majorana bound states located at the two surface terminations. We explain the topological transition in terms of a band inversion in the Caroli-de Gennes-Matricon vortex bound states and discuss favorable material parameters.

Wave-packet continuum discretisation for nucleon-nucleon scattering predictions

Publisher: name: arXiv
Year: 2021
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: In this paper we analyse the efficiency, precision, and accuracy of computing elastic nucleon-nucleon (NN) scattering amplitudes with the wave-packet continuum discretisation method (WPCD). This method provides approximate scattering solutions at multiple scattering energies simultaneously. We therefore utilise a graphics processing unit (GPU) to explore the benefits of this inherent parallelism. From a theoretical perspective, the WPCD method promises a speedup compared to a standard matrix-inversion method. We use the chiral NNLO$_{\rm opt}$ interaction to demonstrate that WPCD enables efficient computation of NN scattering amplitudes provided one can tolerate an averaged method error of $~1-5$ mb in the total cross section at scattering energies $0-350$ MeV in the laboratory frame of reference. Considering only scattering energies $\sim40-350$ MeV, we find a smaller method error of $\lesssim 1-2$ mb. By increasing the number of wave-packets we can further reduce the overall method error. However, the parallel leverage of the WPCD method will be offset by the increased size of the resulting discretisation mesh. In practice, a GPU-implementation is mainly advantageous for matrices that fit in the fast on-chip shared memory. We find that WPCD is a promising method for computationally efficient, statistical analyses of nuclear interactions from effective field theory, where we can utilise Bayesian inference methods to incorporate relevant uncertainties.

Retraction maps: a seed of geometric integrators

description: The classical notion of retraction map used to approximate geodesics is extended and rigorously defined to become a powerful tool to construct geometric integrators and it is called discretization map. Using the geometry of the tangent and cotangent bundles, we are able to tangently and cotangent lift such a map so that these lifts inherit the same properties as the original one and they continue to be discretization maps. In particular, the cotangent lift of a discretization map is a natural symplectomorphism, what plays a key role for constructing geometric integrators and symplectic methods. As a result, a wide range of (higer-order) numerical methods are recovered and canonically constructed by using different discretization maps, as well as some operations with Lagrangian submanifolds.

description: We study two model selection settings in stochastic linear bandits (LB). In the first setting, which we refer to as feature selection, the expected reward of the LB problem is in the linear span of at least one of $M$ feature maps (models). In the second setting, the reward parameter of the LB problem is arbitrarily selected from $M$ models represented as (possibly) overlapping balls in $\mathbb R^d$. However, the agent only has access to misspecified models, i.e.,~estimates of the centers and radii of the balls. We refer to this setting as parameter selection. For each setting, we develop and analyze a computationally efficient algorithm that is based on a reduction from bandits to full-information problems. This allows us to obtain regret bounds that are not worse (up to a $\sqrt{\log M}$ factor) than the case where the true model is known. This is the best-reported dependence on the number of models $M$ in these settings. Finally, we empirically show the effectiveness of our algorithms using synthetic and real-world experiments.

description: In this present work, we uphold the standard model (SM) augmented with two right-handed (RH) neutrinos along with two singlet neutral fermions to generate active neutrino masses via (2,2) inverse see-saw mechanism. All entries of the neutrino mass matrix are taken to be complex to make this study a general one. We also investigate if the parameter points compatible with the neutrino oscillation data simultaneously satisfy the experimental bounds coming from the lepton flavour violating (LFV) decays : $μ\to e γ,~ τ\to e γ, ~ τ\to μγ$. This study also explores the prospect of producing the baryon asymmetry of the universe through resonant leptogenesis. Here the resonant leptogenesis is induced by the lightest pair of degenerate mass eigenstates. Upon solving the coupled Boltzmann equations, one can divide the multi-dimensional model parameter space into three parts, where the parameter points are compatible with the neutrino oscillation data, constraints coming from the LFV decays and last but not the least, the observed baryon asymmetry of the universe.

description: A sketch of the machine is shown in fig. 1. It is made of two linacs, each giving 100 MeV energy gain, a 2 MeV injector and four bending magnets, shaped so that their trajectories are always perpendicular to the edges. This minimizes vertical defocousing, but anyhow the separation of the orbits is such that focusing quadrupoles can be placed on each individual orbit. With 4 ricir culations one obtains a 1 GeV extracted beam. In this note we investigate only the phase evolution of particles injected with a phase difference with respect to the synchronous phase [𝛷s].

description: In this paper, we consider approximate Frank-Wolfe (FW) algorithms to solve convex optimization problems over graph-structured support sets where the linear minimization oracle (LMO) cannot be efficiently obtained in general. We first demonstrate that two popular approximation assumptions (additive and multiplicative gap errors) are not applicable in that no cheap gap-approximate LMO oracle exists. Thus, approximate dual maximization oracles (DMO) are proposed, which approximate the inner product rather than the gap. We prove that the standard FW method using a $δ$-approximate DMO converges as $\mathcal{O}((1-δ) \sqrt{s}/δ)$ in the worst case, and as $\mathcal{O}(L/(δ^2 t))$ over a $δ$-relaxation of the constraint set. Furthermore, when the solution is on the boundary, a variant of FW converges as $\mathcal{O}(1/t^2)$ under the quadratic growth assumption. Our empirical results suggest that even these improved bounds are pessimistic, showing fast convergence in recovering real-world images with graph-structured sparsity.

description: Knitting is an effective technique for producing complex three-dimensional surfaces owing to the inherent flexibility of interlooped yarns and recent advances in manufacturing providing better control of local stitch patterns. Fully yarn-level modelling of large-scale knitted membranes is not feasible. Therefore, we use a two-scale homogenisation approach and model the membrane as a Kirchhoff-Love shell on the macroscale and as Euler-Bernoulli rods on the microscale. The governing equations for both the shell and the rod are discretised with cubic B-spline basis functions. For homogenisation we consider only the in-plane response of the membrane. The solution of the nonlinear microscale problem requires a significant amount of time due to the large deformations and the enforcement of contact constraints, rendering conventional online computational homogenisation approaches infeasible. To sidestep this problem, we use a pre-trained statistical Gaussian Process Regression (GPR) model to map the macroscale deformations to macroscale stresses. During the offline learning phase, the GPR model is trained by solving the microscale problem for a sufficiently rich set of deformation states obtained by either uniform or Sobol sampling. The trained GPR model encodes the nonlinearities and anisotropies present in the microscale and serves as a material model for the membrane response of the macroscale shell. The bending response can be chosen in dependence of the mesh size to penalise the fine out-of-plane wrinkling of the membrane. After verifying and validating the different components of the proposed approach, we introduce several examples involving membranes subjected to tension and shear to demonstrate its versatility and good performance.

description: We investigate the generation of non-classical states of spins coupled to a common cavity by means of a collective driving of the spins. We propose a control strategy using specifically designed series of short coherent and squeezing pulses, which have the key advantage of being experimentally implementable with the state-of-the art techniques. The parameters of the control sequence are found by means of optimization algorithms. We consider the cases of two and four spins, the goal being either to reach a well-defined target state or a state maximizing a measure of non-classicality. We discuss the influence of cavity damping and spin offset on the generation of non-classical states. We also explore to which extent squeezing fields help enhancing the efficiency of the control process.

description: Superradiance is the enhanced emission of photons from quantum emitters collectively coupling to the same optical mode. However, disorder in the resonant frequencies of the quantum emitters can perturb this effect. In this paper, we study the interplay between superradiance and spectral disorder in a dynamically modulated Tavis-Cummings model. Through numerical simulations and analytical calculations, we show that the effective cooperativity of the superradiant mode, which is always formed over an extensive number of emitters, can be multiplicatively enhanced with a quantum control protocol modulating the resonant frequency of the optical mode. Our results are relevant to experimental demonstration of superradiant effects in solid-state quantum optical systems, wherein the spectral disorder is a significant technological impediment towards achieving photon-mediated emitter-emitter couplings.

description: We introduce a new matrix operation on a pair of matrices, $\text{swirl}(A,X),$ and discuss its implications on the limiting spectral distribution. In a special case, the resultant ensemble converges almost surely to the Rayleigh distribution. In proving this, we provide a novel combinatorial proof that the random matrix ensemble of circulant Hankel matrices converges almost surely to the Rayleigh distribution, using the method of moments.

description: Esta tesis recorre dos caminos convergentes en la historia moderna y su impacto en el desarrollo de la sociedad en las ciudades. Por un lado la creación de la cartografía como herramienta representativa y simbólica; y por otro el desarrollo de la tecnología digital y el software.

En las últimas dos décadas, la convergencia de estos caminos ha ofre- cido diversas respuestas a las necesidades humanas y sociales, dando lugar a nuevas teorías y nuevos avances tecnológicos. En este sentido, nos preguntamos qué lugar tienen estos avances en la construcción de futuros desarrollos en relación con la sociedad, a través de diferentes métodos de indagación.

Esta tesis se compone de cinco capítulos que se articulan entre sí a mo- do de construcción narrativa. Partimos de un análisis de la cartografía como elemento constructor de la historia de la sociedad occidental, abordada desde los Estudios Sociales de la Tecnología. Posteriormente, abordamos a la cartografía como objeto constituyente de la modernidad desde el análisis semiótico, esquematizando su capacidad comunicacional, ética y estética.

La segunda parte de esta tesis constituye un recorrido discursivo con- temporáneo. Por un lado, recopilamos los principales argumentos en torno a la relación entre tecnología y espacio urbano; por el otro, abordamos los debates de la cartografía contemporánea y digital en torno a los procesos urbanos, para ello estudiamos un caso local.

Finalmente, desarrollamos un debate sobre los principales cambios que suscitan en las diferentes disciplinas que se preocupan por la relación tecnología-sociedad.

Como conclusión, podremos encontrar que la especialización de múlti- ples disciplinas convergen en el desarrollo de soluciones para un mundo altamente urbanizado. La utilidad de las representaciones urbanas está en considerarlas como constructores en las relaciones de poder, posible gra- cias a las oportunidades que la tecnología aporta. Y que a su vez, permite el estudio de fenómenos sociales que constituyen nuevas teorías sociales, manteniendo la complejidad y las controversias que se dan en los espacios urbanos.

description: Vengono riportati di seguito i risultati del confronto fra le uscite del codice bidimensionale (Magnet) e tridimensionale (Profi). Ai due codici è stata data la stessa geometria, figura 1, dove il profilo circolare del polo è stato approssimato con tre tratti rettilinei. Nella figura 2 sono riportati gli andamenti dei campi previsti dai codici e la curva teorica, come si può vedere c'è un buon accordo tra le varie curve che tendono a distinguersi oltre i 14 mm circa dal centro. Nella figura 3 l'andamento dei campi è riportato per vari piani in z. Non sono riportate le curve tra z=0 e 2= 17.25 cm, poiché sono praticamente coincidenti, mentre oltre tale valore si fa sensibile l'effetto di fringing per la terminazione del quadrupolo. Tale effetto è meglio visibile nella figura 4 che riporta l'andamento della componente Bx del campo per due valori di x. Lo lunghezza meccanica considerata nel codice tridimensionale è pari alla lunghezza magnetica richiesta diminuita di un raggio di cerchio di gola ( 37 cm). La figura 5 riporta l'andamento del gradiente lungo l'asse del quadrupolo, valutato a due valori di x, x=7.5 mm e x=17.5 mm (...).

description: È stato valutato l'andamento longitudinale del gradiente del campo per la struttura AF-8. Nelle figure 1 e 2 viene mostrata la funzione (...) lungo un semiasse, rispettivamente nei piani y=2mm e y=3mm secondo le mappe tridimensionali. Essendo tali mappe ottenute con profilo polare piatto (vedi memo G-79), esse hanno solo valore relativo per cui è stato assunto come fattore di normalizzazione il valore del gradiente in z=0. Si nota quindi che a causa della lunghezza finita del sestupolo, il gradiente varia lungo l'asse della lente fino ad annullarsi a circa 10cm dal centro. Per ogni piano è stato inoltre calcolato il valore delle derivate seconde, che indichiamo con D², ottenuto dalle mappe di campo bidimensionali per profilo parabolico e circolare ovviamente a z=0. In tabella I vengono mostrati i risultati di tali analisi numeriche per i due profili nelle due sezioni indicate. Nell'ultima colonna abbiamo (...) cioè l'integrale normalizzato moltiplicato per il valore del gradiente secondo le mappe bidimensionali con geometria reale. Lo stesso procedimento è stato seguito per l'analisi delle derivate lungo l'asse x. I risultati sono riassunti in tabella II. Dal confronto delle due tabelle e dall'andamento dei campi, per profilo parabolico, mostrato in figura 3 e 4 è evidente la simmetria lungo le due direzioni radiali x e y. Per ottenere un gradiente integrato più elevato sono possibili delle variazioni o per la densità di corrente o per la lunghezza meccanica. Occorre notare (vedi memo G-79) che la lunghezza meccanica adottata nei calcoli con codice tridimensionale corrisponde alla lunghezza magnetica voluta meno un diametro del cerchio di gola, assunzione che si è rivelata troppo ottimistica.

description: We examine iteration of certain skew-products on the bidisk whose components are rational inner functions, with emphasis on simple maps of the form $Φ(z_1,z_2) = (ϕ(z_1,z_2), z_2)$. If $ϕ$ has degree $1$ in the first variable, the dynamics on each horizontal fiber can be described in terms of Möbius transformations but the global dynamics on the $2$-torus exhibit some complexity, encoded in terms of certain $\mathbb{T}^2$-symmetric polynomials. We describe the dynamical behavior of such mappings $Φ$ and give criteria for different configurations of fixed point curves and rotation belts in terms of zeros of a related one-variable polynomial.
