The Collapse and Revival of Bell-nonlocaliy for Continuous Variables
2015
We study the quantum nonlocality dynamics of pair coherent states in the double Jaynes-Cummings model. It is shown that the Bell-inequality violation can be fully destroyed in a finite time and then recovered. The inequality violation can obtain better recovery when only one atom couples to either of the cavity fields. Besides, the correlation property of cavity fields is more feasible affected when the atom interacts resonantly with the second cavity field. The difference in the number of photons of the two modes may play an important role in the case of resonant interaciton especially.
