- Abstract
We investigate the dynamics of quantum correlations for the Tavis–Comming model in continuous dephasing process. It is shown that quantum discord and entanglement can reach stationary value, and quantum Zeno effect occurs in strong-coupling region. Furthermore, we explore the influence of continuous dephasing process on the trace distance between two marginal states of the two atoms and find that the trace distance also achieve a constant value during time evolution.
