Time-dependent Robin boundary conditions in the dynamical Casimir effect
Motivated by experiments in which moving boundaries are simulated by
time-dependent properties of static systems, we discuss the model of a massless
scalar field submitted to a time-dependent Robin boundary condition (BC) at a
static mirror in 1+1 dimensions. Using a perturbative approach, we compute the
spectral distribution of the created particles and the total particle creation
rate, considering a thermal state as the initial field state.Comment: 10 pages, 3 figures. To appear in proceedings of Conference on
