    "abstract": "We extend the quantum theory of dissipation in the context of\nsystem-reservoir model, where the reservoir in question is kept in a\nnonequilibrium condition. Based on a systematic separation of time scales\ninvolved in the dynamics, appropriate generalizations of the\nfluctuation-dissipation and Einstein\u0027s relations have been pointed out. We show\nthat the Wigner-Weisskopf decay of the system mode results in a rate constant\nwhich depending on the relaxation of nonequilibrium bath is dynamically\nmodified. We also calculate the time-dependent spectra of a cavity mode with a\nsuitable gain when the cavity is kept in contact with a nonequilibrium bath.",
