摘要

本文用主方程给出了耗散腔中与场模耦合的原子动力学的精确解析描述。研究了n≠0的热光子对纠缠态和相干损耗的影响。研究发现，与零温度(n=0)情况相比，该场被抑制而无法进入纯态，相干性损失更快。

The effects of thermal photons on Fisher information dynamics for a dispersive Jaynes-Cummings model

We give the exact analytical description for the dynamics of an atom coupled to field mode in dissipative cavity by using the master equation. The effects of thermal photon (n≠0) on entanglement and coherence loss are achievement. It is found that the field is inhibited from going into a pure state and coherence is lost faster than in the case of zero temperature (n=0).
