Quantum batteries at the verge of a phase transition
(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, ...
Open strings on D-branes from ABJM
(2015-06-08)
Abstract: We study open strings on giant gravitons (D-branes on cycles) in the ABJM/AdS<inf>4</inf> × ℂℙ<sup>3</sup> correspondence. We find that their energy spectrum has the same form as the one for closed strings, with ...
Quantum Monte Carlo studies of a trimer scaling function with microscopic two- And three-body interactions
(2021-09-01)
We present an energy scaling function to predict, in a specific range, the energy of bosonic trimers with large scattering lengths and finite range interactions, which is validated by quantum Monte Carlo calculations using ...
A quantitative approach to perfect one-factorizations of complete bipartite graphs
(E-JC, 2015)
Given a one-factorization F of the complete bipartite graph Kn;n, let pf(F) de-
note the number of Hamiltonian cycles obtained by taking pairwise unions of perfect
matchings in F. Let pf(n) be the maximum of pf(F) over ...
Aspectos qualitativos de sistemas diferenciais suaves por partes: regularização, bifurcação, ciclos limite e função período.
(Universidade Estadual Paulista (Unesp), 2021-01-27)
Neste trabalho estamos interessados em alguns tópicos e problemas acerca da teoria qualitativa dos sistemas diferenciais. Analisamos algumas bifurcações de uma classe de sistemas suaves por partes com bordos singulares via ...
Clasificación de foliaciones elípticas inducidas por campos cuadráticos reales con centro
(Pontificia Universidad Católica del PerúPE, 2017)
Caos y desorden en el circuito de Chua
(Universidad Michoacana de San Nicolás de Hidalgo, 2012-12)
The Chua circuit is the simplest non-linear autonomous circuit that presents chaotic behavior; That is to say, it presents an extreme sensitivity to the change of the initial conditions. Under certain conditions the Chua ...
Birth Of Limit Cycles Bifurcating From A Nonsmooth Center
(Elsevier Masson SAS, 2014)
Campos de vetores suaves por partes: aspectos teóricos e aplicações
(Universidade Estadual Paulista (Unesp), 2020-01-22)
Nesta tese abordaremos aspectos qualitativos e dinâmicos de problemas envolvendo campos de vetores suaves por partes, também conhecidos como campos descontínuos. Primeiramente, apresentamos aplicações da teoria de campos ...
Ciclos límite de sistemas hamiltonianos perturbados y ceros de integrales abelianas
(Universidad Michoacana de San Nicolás de Hidalgo, 2007-08)
In the qualitative theory of differential equations, the study of limit cycles is very important as they provide relevant information for the description of the phase portrait of a differential equation. But nevertheless ...
