| Abstract: | The entanglement evolution of two two-level atoms in Bell states interacting with a single-mode vacuum cavity respectively is investigated by means of concurrence. The results obtained using the numerical method show that the entanglement of two atoms displays periodic oscillation behavior and its oscillation period decreases with increasing of coupling constant between atom and cavity. |
