Refining Deutsch's approach to thermalization
arXiv:2102.06057 · doi:10.1103/PhysRevE.103.022119
Abstract
The ground breaking investigation by Deutsch [Phys. Rev. A 43, 2046 (1991)] of how closed many-body quantum systems approach thermal equilibrium is revisited. It is shown how to carry out some important steps which were still missing in that paper. Moreover, the class of admitted systems is considerably extended.
