腔场损耗对Ξ型三能级原子与双模光场非共振相互作用系统熵的影响

Effects of cavity dissipation on entropy of non-resonant interacting system of Ξ-type three-level atom and two-mode field

研究了Ξ型三能级原子与双模相干态场非共振相互作用过程中,腔场存在能量损耗时,系统线性熵、光场线性熵和原子线性熵的时间演化特性,讨论了能量损耗、双模光场的平均光子数和光场与原子的耦合程度对各线性熵的影响.

The time evolution of linear entropies of field-atom coupling system,field and atom in the system of Ξ-type three-level atom interacting with two-mode coherent field nonresonantly in a energy-damping cavity is investigated. The effects of energy damping, the mean photon numders of a two-mode coherent field and the intensity coupling of the field with the atom on all the above entropies are discussed.
