Summary:We propose a feasible scheme to generate electromagnetically induced transparency (EIT) and quadripartite macroscopic entanglement in an optomechanical system with one fixed mirror and three movable perfectly reflecting mirrors. We explore the EIT phenomena in this optomechanical system. Results show the appearance of EIT dips in the output field. Moreover, we demonstrate how steady-state quadripartite entanglement can be generated via radiation pressure. We also quantify the bipartite entanglement in each field-mirror subsystem and in the mirror-mirror subsystem. Findings show that a high intensity of entanglement between two subsystems can be achieved.
