本文研究了初始处于任意纯态的二能级原子在腔中由于动力学Casimir效应从真空中产生光子的解析解。执行小酉变换，我们得到封闭的概率振幅和其他重要的数量在共振/色散制度的解析表达式。
We study analytically the photon generation from vacuum due to the Dynamical Casimir effect in a cavity with a two-level atom, prepared initially in an arbitrary pure state. Performing small unitary transformations we obtain closed analytical expressions for the probability amplitudes and other important quantities in the resonant/dispersive regimes.
