| Abstract: | The evolution of the field (atomic) entropy in a system of a quasi_Λ_type four level atom interacting with an uncoupled two_mode coherent field is investigated. The effects of initial atomic state, the initial mean photon number and the splitting of the atomic energy levels on the entropy are discussed. The system reduces to that of a two level or three level atom interacting with a single mode coherent field in special cases. |
