Quantum Chaos and Thermalization in Isolated Systems of Interacting Particles.
(American Physical Society, 2016)
This review is devoted to the problem of thermalization in a small isolated conglomerate of interacting constituents. A variety of physically important systems of intensive current interest belong to this category: complex ...
Realistic Many-Body Quantum Systems vs. Full Random Matrices: Static and Dynamical Properties.
We study the static and dynamical properties of isolated many-body quantum systems and compare them with the results for full random matrices. In doing so, we link concepts from quantum information theory with those from ...
Onset of quantum chaos in one-dimensional bosonic and fermionic systems and its relation to thermalization.
(American Physical Society, 2010)
By means of full exact diagonalization, we study level statistics and the structure of the eigenvectors of one-dimensional gapless bosonic and fermionic systems across the transition from integrability to quantum chaos. ...
Quantum chaos and thermalization in gapped systems.
(American Physical Society, 2010-07)
We investigate the onset of thermalization and quantum chaos in finite one-dimensional gapped systems of hard-core bosons. Integrability in these systems is broken by next-nearest-neighbor repulsive interactions, which ...
Relaxation, chaos, and thermalization in a three-mode model of a Bose–Einstein condensate.
(IOP Publishing, 2018-11-27)
We study the complex quantum dynamics of a system of many interacting atoms in an elongated an harmonic trap. The system is initially in a Bose–Einstein condensed state, well described by Thomas–Fermi profile in the ...
From few- to many-body quantum systems.
(IOP Publishing, 2018-09-03)
How many particles are necessary to make a quantum system many-body? To answer this question, we take as reference for the many-body limit a quantum system at half-filling and compare its properties with those of a system ...
