CAVITY WITH LOSSES - A DESCRIPTION USING SUPEROPERATORS

Cavities with losses are usually described by a master equation. This equation describes the rate of change of the density matrix, with resp ect to time, of a given electromagnetic field due to an interaction or losses. The most common method of solution of a master equation is to transform it into a Fokker-Planck type equation. In this paper we use another method, the so-called superoperators method. We apply this me thod to a damped cavity in which an electromagnetic field is injected.
