摘要：

The dynamical Casimir effect (DCE) tells that the photons can be generated in the vacuum cavity. We here show how the squeezing of the cavity mode and the coupling between the atoms and cavity influence the DCE. We show that the atoms can be served as probe to detect the DCE. Our results show that the photon number increases with the increasing of the photonic squeezing but decreases with the atom-cavity coupling. The excitation number of the atom increases with both of the increasing of the squeezing and the atom-cavity coupling strength.
