In this work, the authors consider the problem of a system coupled to an ensemble of independent harmonic oscillators acting as a reservoir. They 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 considered and their ranges of validity and differences are examined. 20 refs.
