dc.descriptionIt is shown that the the quantum phase space distributions corresponding to a density operator $ρ$ can be expressed, in thermofield dynamics, as overlaps between the state $\mid ρ>$ and "thermal" coherent states. The usefulness of this approach is brought out in the context of a master equation describing a nonlinear oscillator for which exact expressions for the quantum phase distributions for an arbitrary initial condition are derived.
