Tunable phonon-photon coupling induces double MMIT and enhances slow light in an atom-opto-magnomechanics

Abstract: In this paper we theoretically investigate the magnomechanically induced transparency phenomenon and the slow/fast light effect in the situation where an atomic ensemble is placed inside the hybrid cavity of an opto-magnomechanical system. The system is driven by dual optical and phononic drives. We show double magnomechanically induced transparency (MMIT) in the probe output spectrum by exploiting the phonon-photon coupling strength. In addition, the fast and slow light effects in the system are explored. Besides, we show that the slow light profiles is enhanced by adjusting phonon-photon coupling strength. This result may have potential applications in quantum information processing and communication.
