摘要

Quantum entanglement dynamics of two Tavis Cummings atoms interacting with the quantum light sources in a cavity is investigated. The results show the phenomenon that the concurrence disappears abruptly in a finite time, which depends on the initial atomic states and the properties of squeezed states. We find that there are two decoherence- free states in squeezed vacuum fields; one is the singlet state, and the other entangled state is the state that combines both excited states and ground states with a relative phase being equal to the phase of the squeezed state.
