Abstract

We calculate the number of photons produced by the parametric resonance in a cavity with vibrating walls. We consider the case that the frequency of vibrating wall is nω1(n=1,2,3,...)n \omega_1 (n=1,2,3,...) which is a generalization of other works considering only 2ω12 \omega_1, where ω1\omega_1 is the fundamental-mode frequency of the electromagnetic field in the cavity. For the calculation of time-evolution of quantum fields, we introduce a new method which is borrowed from the time-dependent perturbation theory of the usual quantum mechanics. This perturbation method makes it possible to calculate the photon number for any nn and to observe clearly the effect of the parametric resonance.
