Relaxation of a three-level atom in stochastic fields and its spectroscopic properties

Relaxation of a three-level atom in stochastic fields and its spectroscopic properties

Relaxation of a motionless three-level atom with a non-equidistant spectrum in a photon heat bath and an external stochastic field is investigated. In the Markovian approximation of the relaxation processes a master equation for the reduced density matrix is derived by making use of the averaging ov...
