Abstract

We study the dynamical Casimir effect and the dynamical behaviors of the two-atom in a non-stationary cavity containing two two-level atoms. By solving the problem in a matrix method, we obtain an analytic solution. The results show that the larger of the atom-field coupling coefficients and the coupling coefficient of atoms, the fewer photons generated, but the probability of double excitation of the two-atom increases with the coupling coefficients. The squeezed coefficient enhances the generation rate of the created photons and the possibility of the atoms in the excited states.

Keywords
