Dynamic effects of electromagnetic wave on a damped two-level atom: Exact solution via path integral
Mekki Aouachria, Farida Halimi
The spin coherent state path integral describing the dynamics of a two-level system interacting with electromagnetic wave of circular polarization is considered. The propagator is first written in the standard form by replacing the spin by a unit vector aligned along the polar and azimuthal directions. Then it is determined exactly using perturbation methods. Thus, the exact energy spectra with corresponding wave functions are deduced.
