本文用解析和数值方法研究了腔中两个静止二能级原子与共振场模通过Tavis-Cummings哈密顿量相互作用的Casimir效应。我们确定的调制频率的场和原子激发产生和研究相应的动力学行为的情况下的阻尼。结果表明，双原子系统允许在不中断生长的情况下监测光子的产生，并且在此过程中可以产生不同的纠缠态。
We study analytically and numerically the dynamical Casimir effect in a cavity containing two stationary 2-level atoms that interact with the resonance field mode via the Tavis-Cummings Hamiltonian. We determine the modulation frequencies for which the field and atomic excitations are generated and study the corresponding dynamical behaviors in the absence of damping. It is shown that the two-atom setup allows for monitoring of photon generation without interrupting the growth, and different entangled states can be generated during the process.
