Resumen:
We analyze the introduction of dissipative effects in the study of the
dynamical Casimir effect. We consider a toy model for an electromagnetic cavity that
contains a semiconducting thin shell, which is irradiated with short laser pulses in
order to produce periodic oscillations of its conductivity. The coupling between the
quantum field in the cavity and the microscopic degrees of freedom of the shell induces
dissipation and noise in the dynamics of the field. We argue that the photon creation
process should be described in terms of a damped oscillator with nonlocal dissipation
and colored noise.
