我们研究了动态Casimir效应及其Rydberg原子探测。光子是在具有半导体板的等离子体镜的谐振腔中产生的，该等离子体镜由周期性激光脉冲照射。导出了产生和湮灭算符的正则哈密顿量，显示了耦合的显式时间变化，这源于外部配置，如非稳态等离子体镜。产生的光子的数量被评估为从具有哈密顿量的海森堡方程压缩。然后，通过原子与光场的相互作用，研究了作为原子激发的光子的探测。一些考虑是一个可行的实验实现与半导体等离子体镜。
We investigate the dynamical Casimir effect and its detection with Rydberg atoms. The photons are created in a resonant cavity with a plasma mirror of a semiconductor slab which is irradiated by periodic laser pulses. The canonical Hamiltonian is derived for the creation and annihilation operators, showing the explicit time variation in the couplings, which originates from the external configuration such as a nonstationary plasma mirror. The number of created photons is evaluated as squeezing from the Heisenberg equations with the Hamiltonian. Then the detection of the photons as the atomic excitations is examined through the atom-field interaction. Some consideration is made for a feasible experimental realization with a semiconductor plasma mirror.
