三能级原子的腔动力学Casimir效应

Cavity Dynamical Casimir Effect in the presence of a three-level atom

A. V. Dodonov, V. V. Dodonov

摘要:

我们考虑了一个处于梯形或V型组态的阻尼三能级原子与一个单腔模耦合的情形,该腔模的真空态被动态Casimir效应放大。我们得到了与时间相关的几率的近似解析表达式和精确的数值结果,表明第三能级的存在改变了光子的统计特性,其布居数可以作为真空产生光子的证据.

英文摘要:

We consider the scenario in which a damped three-level atom in the ladder or V configurations is coupled to a single cavity mode whose vacuum state is amplified by dint of the dynamical Casimir effect. We obtain approximate analytical expressions and exact numerical results for the time-dependent probabilities, demonstrating that the presence of the third level modifies the photon statistics and its population can serve as a witness of photon generation from vacuum.
