Abstract:
The properties of solutions of the
Gorini–Kossakowski-Sudarshan–Lindblad (GKSL) equation for the
density operator (matrix) of a system that has nondegenerate energy
spectrum and weakly interacts with a reservoir are considered.
Conditions for the existence of solutions for which the density matrix has off-diagonal
entries (“coherences”) not tending to
zero at large times are derived.
Keywords:
dynamics of open quantum systems,
Gorini–Kossakowski–Sudarshan–Lindblad equation, decoherence.
