摘要
In this paper, we have studied the dynamics of nonlocality for a hybrid entangled state in a thermal reservoir. The density operator of the system is obtained by using a superoperator method. The dynamics of nonlocality for the mixed hybrid entangled state is uncovered by using the Bell operator based on the 'pseudospin operator' for. a light field (Chen Z B, Pan J W, Hou G and Zhang Y D 2002 Phys. Rev. Lett. 88 040406). The dynamics of nonlocality has also been studied using other Bell operators.
