Abstract

We give a technique for calculating the occupation number of quantum fields in time-dependent backgrounds by using the relation between one-dimensional quantum oscillators and two-dimensional classical oscillators. We illustrate our method by giving closed analytical results for the time-dependent spectrum of occupation numbers during gravitational collapse in any number of dimensions.
