    "abstract": "It is shown that the the quantum phase space distributions corresponding to a\ndensity operator $\\rho$ can be expressed, in thermofield dynamics, as overlaps\nbetween the state $\\mid \\rho \u003e$ and \"thermal\" coherent states. The usefulness\nof this approach is brought out in the context of a master equation describing\na nonlinear oscillator for which exact expressions for the quantum phase\ndistributions for an arbitrary initial condition are derived.",
