Abstract

In this paper, the dynamical evolution of the entanglement of gravitational Jaynes-Cummings model with respect to counter-rotating terms is examined. First, in the gravitational the Jaynes-Cummings model with respect to counter-rotating terms the effective Hamiltonian of the Schrödinger equation in the interaction picture is obtained. Then, by transforming the Schrödinger equation to two differential equations, the amplitudes of probability are obtained. In this case, by obtaining the entanglement of the system, its time evolution in the presence of certain parameters is investigated.

Keywords
