Abstract A spectator system in an atoms-cavity QED model is investigated. The subsystem initial state is prepared as one of the Bell states or one mixed state. It is shown that (i) the dynamics of Bell states are independent on the initial states; (ii) the concurrence dynamics can be engineered by a controlling light field.
