Noncanonical statistics of a finite quantum system with non-negligible system-bath coupling
Noncanonical statistics of a finite quantum system with non-negligible system-bath coupling
The canonical statistics describes the statistical properties of an open system by assuming its coupling with the heat bath is infinitesimal in comparison with the total energy in thermodynamic limit. In this paper, we generally derive a noncanonical density matrix for the open system with a finite coupling to the …
