Ideal Gas Law for a Quantum Particle
Alejandro M. F Rivas, Eduardo G. Vergini, Leonardo Ermann +1
The question of how classical thermodynamic laws emerge from the underlying quantum substrate lies at the foundations of physics. Here, we examine the validity of the ideal gas law…
Impact of chaos on precursors of quantum criticality
Ignacio García-Mata, Diego A. Wisniacki, Eduardo G. Vergini
Excited-state quantum phase transitions (ESQPTs) are critical phenomena that generate singularities in the spectrum of quantum systems. {For systems with a classical counterpart,}…
The short periodic orbit method for excited chaotic eigenfunctions
F. Revuelta, E. Vergini, R. M. Benito +1
In this paper [published in Phys. Rev. E 102, 042210 (2020)], a new method for the calculation of excited chaotic eigenfunctions in arbitrary energy windows is presented. We demons…
Kolmogorov turbulence defeated by Anderson localization for a Bose-Einstein condensate in a Sinai-oscillator trap
Leonardo Ermann, Eduardo Vergini, Dima L. Shepelyansky
We study the dynamics of a Bose-Einstein condensate in a Sinai-oscillator trap under a monochromatic driving force. Such a trap is formed by a harmonic potential and a repulsive di…
Semiclassical basis sets for the computation of molecular vibrational states
F. Revuelta, E. Vergini, R. M. Benito +1
In this paper, we extend a method recently reported [Phys. Rev. E 87, 042921 (2012)] for the calculation of the eigestates of classically highly chaotic systems to cases of mixed d…
Dynamics and thermalization of Bose-Einstein condensate in Sinai oscillator trap
Leonardo Ermann, Eduardo Vergini, Dima L. Shepelyansky
We study numerically the evolution of Bose-Einstein condensate in the Sinai oscillator trap described by the Gross-Pitaevskii equation in two dimensions. In the absence of interact…
