灰体场中原子和光场的熵交换研究

Entropy Exchange of Atom Interacting with Gray-body Radiation Field

研究了二能级原子与灰体场相互作用过程中原子和光场线性熵的交换规律,讨论了失谐量以及腔场光子数分布对原子和光场线性熵交换的影响。结果表明,原子和光场线性熵的振动周期由失谐量决定,熵交换量的振幅与入射光强度、腔体温度及吸收系数有关。

Entropy exchange of atom interacting with gray-body radiation field in Jaynes-Cummings Model is investigated. The effect of detuning and the photon-number distribution on entropy exchange is discussed. The result shows that the vibration cycle of the atom and photon field linear entropy is determined by detuning, the altitude of the entropy exchanging is related with radiation intensity, cav- ity temperature and its absorption coefficient.
