(Springer, 2018)We prove propagation of chaos at explicit polynomial rates in Wasserstein distance for Kac's N-particle system associated with the spatially homogeneous Boltzmann equation for Maxwell molecules. Our approach is mainly based ...
-
(Springer New York LLC, 2019)© 2018, Mathematica Josephina, Inc.For a connected simply connected nilpotent Lie group G with Lie algebra g and unitary dual G^ one has (a) a global quantization of operator-valued symbols defined on G× G^ , involving the ...
-
(IOP, 2022)Starting from the observation that the reduced state of a system strongly coupled to a bath is, in general, an athermal state, we introduce and study a cyclic battery-charger quantum device that is in thermal equilibrium, ...
-
(American Physical Society, 2015)We study the quantum spin waves associated to skyrmion textures. We show that the zero-point energy associated to the quantum spin fluctuations of a noncollinear spin texture produce Casimir-like magnetic fields. We study ...
-
(American Physical Society, USA, 2021)We report on the fate of the quantum Hall effect in graphene under intense laser illumination. By using Floquet theory combined with both a low energy description and full tight-binding models, we clarify the selection ...
-
(American Physical Society, 2014)We calculate the effect of spin waves on the properties of finite-size spin chains with a chiral spin ground state observed on biatomic Fe chains deposited on iridium(001). The system is described with a Heisenberg model ...
-
(Elsevier, 2015)We calculate the electrical conductivity of a metallic sample under the effects of distributed impurities and a random distribution of grain boundaries by means of a quantum mechanical procedure based on Kubo formula. ...
-
(2002)We look at quasar environment in the context of large-scale structure (LSS) – a new approach, giving a more informed interpretation of quasar–galaxy correlations. This paper presents our first results for a sample of z ...
-
(Schloss Dagstuhl- Leibniz-Zentrum fur Informatik GmbH, Dagstuhl Publishing, 2018)We consider two optimization problems in planar graphs. In Maximum Weight Independent Set of Objects we are given a graph G and a family D of objects, each being a connected subgraph of G with a prescribed weight, and the ...
-
(Elsevier, 2021)Words are sequences of letters over a finite alphabet. We study two intimately related topics for this object: quasi-randomness and limit theory. With respect to the first topic we investigate the notion of uniform ...

-
(2009)In this paper we study quasi-stationarity for a large class of Kolmogorov diffusions. The main novelty here is that we allow the drift to go to−∞at the origin, and the diffusion to have an entrance boundary at +∞. These ...
-
(Ecole Polytechnique, 2020)We study a class of multi-species birth-and-death processes going almost surely to extinction and admitting a unique quasi-stationary distribution (qsd for short). When rescaled by K and in the limit K ! +1, the realizations ...
-
(2011)We study the probabilistic evolution of a birth and death continuous time measure-valued process with mutations and ecological interactions. The individuals are characterized by (phenotypic) traits that take values in a ...
-
(American Physical Society, 2013)We propose a route to spatiotemporal chaos for one-dimensional stationary patterns, which is a natural extension of the quasiperiodicity route for low-dimensional chaos to extended systems. This route is studied through ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2003-08)Major- and trace-element, Sr-Nd isotopes, and mineral chemistry data were obtained for a collection of volcanic rock samples erupted by the Cay and Maca. Quaternary volcanoes, Patagonian Andes (similar to45degreesS, Chile). ...
-
(SPRINGER-VERLAG BERLIN, 2005)This paper studies the RDF model from a database perspective. From this point of view it is compared with other database models, particularly with graph database models, which are very close in motivations and use cases ...
-
(ACM, 2014)Graph data appears in a variety of application domains, and many uses of it, such as querying, matching, and transforming data, naturally result in incompletely specified graph data, that is, graph patterns. While queries ...
-
(IOP Pub., 2015)We present the characterization and initial results from the QUEST–La Silla active galactic nucleus (AGN) variability survey. This is an effort to obtain well-sampled optical light curves in extragalactic fields with ...
