摘要: We present a scheme for the electromagnetically-induced-absorption (EIA)-like ground state cooling in a hybrid optomechanical system which is combined by two-level quantum systems (qubits) and a high-$Q$ optomechanical cavity. Under the weak qubit-cavity coupling, the system exhibits an EIA-like effect and this effect is caused by quantum destructive interference that is distinct from the conventional EIA effect driven by quantum constructive interference. More importantly, the EIA-like cooling mechanism can significantly enhance the cooling rate of the hybrid system, enabling the final phonon number beyond the classical cooling limit in the strong optomechanical coupling regime. Meanwhile, the cooling effects of the EIA case is better than that of the normalmode splitting case under the same optomechanical coupling strength and qubit dissipation rate.
