Abstract
We consider the problem of a system coupled to an ensemble of independ ent harmonic oscillators acting as a reservoir. We use an extension of the functional derivative technique to analyze some of the effects of adding stochastic terms to the system-reservoir coupling parameters. Two approaches (quantum master equation and Langevin equation) are con sidered and their ranges of validity and differences are examined.
