Abstract
We introduce an alternative nonperturbative method to the master equation f ormalism of describing the evolution of coupled linear systems. The method utilizes the spectral distribution of the normal modes of the complete syst em to calculate the evolution of the dynamical variables. The dynamical evo lution of the Wigner function for a Schrodinger cat state in a damped cavit y is considered as example. (C) 2000 Elsevier Science B.V. All rights reser ved.
