Abstract
The dynamical Casimir effect and the collective excitation effect are investigated in a resonantly vibrating cavity filled with a gas of two-level atoms without the rotating-wave approximation at finite temperature. Compared with the condition of the rotating-wave approximation, the created photons and the created excitons are more under the non-rotating wave approximation at different temperatures and different total coupling strengths. The numerical results show that the counter-rotating wave terms enhance the dynamical Casimir effect and the collective excitation effect at finite temperature.
