Abstract
We study the entanglement dynamics of strongly driven atoms off-resonantly coupled with cavity fields. We consider conditions characterized not only by the atom–field coupling but also by the atom–field detuning. By studying two different models within the framework of cavity QED, we show that the so-called atomic entanglement sudden death (ESD) always occurs if the atom–field coupling is larger than the atom–field detuning, and is independent of the type of initial atomic state.
