Method of asymptotic operators in statistical mechanics

S. V. Peletminskii, V. I. Prikhod'ko


Abstract: The role the principle of correlation weakening and the ergodic relationships p!ay in determining the secular terms (asymptotic operators) in the perturbation series for the density matrix is considered. The asymptotic operators are used to find the approximate density matrix at a simplified stage of the evolution and to find the density matrix's low-frequency singular part, which determines the system's response to an external perturbation.
