"Dynamical Thermalization of Interacting Fermionic Atoms in a Sinai Oscillator Trap"
Klaus M. Frahm, Leonardo Ermann and Dima L. Shepelyansky
Condens. Matter 4(3) (2019) 76/1-29
We study numerically the problem of dynamical thermalization of interacting cold fermionic atoms placed in an isolated Sinai oscillator trap. This system is characterized by a quantum chaos regime for one-particle dynamics. We show that, for a many-body system of cold atoms, the interactions, with a strength above a certain quantum chaos border given by the Åberg criterion, lead to the Fermi–Dirac distribution and relaxation of many-body initial states to the thermalized state in the absence of any contact with a thermostate. We discuss the properties of this dynamical thermalization and its links with the Loschmidt–Boltzmann dispute.
