Abstract:We propose an efficient scheme to generate macroscopically quantum superposition state with a cavity optomechanical system, which is composed of a quantum Rabi-Stark model coupling to a mechanical oscillator. In a low-energy subspace of the Rabi-Stark model, the dressed states and then the effective Hamiltonian of the system are given. Due to the coupling of the mechanical oscillator and the atomcavity system, if the initial state of the atom-cavity system is one of the dressed states, the mechanical oscil… Show more
