By introducing thermo-entangled state representation , which can map master equations of density operator in quantum statistics as state-vector evolution equations, and using ''dissipative interaction picture we solve the master equation of Jaynes-Cummings model with cavity damping. In addition we derive the Wigner function for density operator when the atom is initially in the up state and the cavity mode is in coherent state.

Unraveling a Driven Damped Harmonic Oscillator through Entangled State Representation

Abstract: Employing the thermo-entangled state representation, the common eigenstates of relative position and the total momentum of a two-mode system, we solve the master equation of a damped harmonic oscillator driven by a time-dependent uniform force field.
