Phys. Rev. A 59, 3049–3059 (1999)Creation of photons in an oscillating cavity with two moving mirrorsReceived 29 October 1998; published in the issue dated April 1999 We study the creation of photons in a one-dimensional oscillating cavity with two perfectly conducting moving walls. By means of a conformal transformation, we derive a set of generalized Moore’s equations whose solution contains the whole information of the radiation field within the cavity. For the case of resonant oscillations we solve these equations using a renormalization-group procedure that appropriately deals with the secular behavior present in a naive perturbative approach. We study the time evolution of the energy density profile and of the number of created photons inside the cavity. © 1999 The American Physical Society URL:
