研究了色散原子环境中两个二能级原子与腔模共振相互作用的纠缠动力学。结果表明，在没有环境的情况下，当只涉及一个激发时，纠缠达到最大值。然后，我们发现，原子环境改变了纠缠动力学，即使对于初始的单光子Fock态，也会导致典型的崩塌-复兴结构。
We study entanglement dynamics of a couple of two-level atoms resonantly interacting with a cavity mode and embedded in a dispersive atomic environment. We show that in the absence of the environment the entanglement reaches its maximum value when only one excitation is involved. Then, we find that the atomic environment modifies that entanglement dynamics and induces a typical collapse-revival structure even for an initial one photon Fock state of the field.
