Thermalization and prethermalization in isolated quantum systems: a theoretical overview

T Mori, TN Ikeda, E Kaminishi… - Journal of Physics B …, 2018 - iopscience.iop.org
The approach to thermal equilibrium, or thermalization, in isolated quantum systems is
among the most fundamental problems in statistical physics. Recent theoretical studies have …

Stationary and dynamical properties of two harmonically trapped bosons in the crossover from two dimensions to one

G Bougas, SI Mistakidis, GM Alshalan, P Schmelcher - Physical Review A, 2020 - APS
We unravel the stationary properties and the interaction quench dynamics of two bosons,
confined in a two-dimensional anisotropic harmonic trap. A transcendental equation is …

Entanglement prethermalization in the Tomonaga-Luttinger model

E Kaminishi, T Mori, TN Ikeda, M Ueda - Physical Review A, 2018 - APS
Prethermalization refers to the relaxation to a quasistationary state before reaching thermal
equilibrium. Recently, it was found that not only local conserved quantities but also …

A simple model for a minimal environment: the two-atom Tavis–Cummings model revisited

GL Deçordi, A Vidiella-Barranco - Journal of Modern Optics, 2018 - Taylor & Francis
Individual quantum systems may be interacting with surrounding environments having a
small number of degrees of freedom. Here we discuss a simple toy model: a system …

A solvable model for decoupling of interacting clusters

AG Volosniev, AS Jensen, NL Harshman… - Europhysics …, 2019 - iopscience.iop.org
We consider M clusters of interacting particles, whose in-group interactions are arbitrary,
and inter-group interactions are approximated by oscillator potentials. We show that there …
