Three resonant energy levels in the presence of a asymmetric damping. A quantum non‐perturbative approach
Marcel Giry, Olivier Henri‐Rousseau
Abstract
Abstract The irreversible evolution at zero temperature of a linear chain of three resonant excited states, the last of them being damped, is studied at zero temperature, using the resolvent method. The matrix elements of the time‐evolution operator and of the reduced density operator are obtained in closed form. The decays contain always three exponentials. Relaxation is always underdamped. Comparison is made with the corresponding classical kinetic model.
