- We solve the Lindblad master equation for the quantum state of a pumped optomechanical system coupled to a thermal bath. We show that when the microwave pump field frequency is on the red sideband of the cavity resonance, the exact form of the state is a beam-split thermal state, and when it is on the blue sideband, it is a two-mode squeezed thermal state. These solutions allow us to determine the mechanical cooling and the entanglement between the microwave and mechanical modes. We find that we can entangle the modes in a thermal environment by activating the two fields sequentially. In this scheme, after cooling the mechanical mode via the red sideband pump, we determine the optimal blue sideband pump field to achieve the maximum entanglement time and the maximum time below a desired correlation variance threshold as a function of the loss rates and equilibrium temperatures of the two modes.
