Phonon pump enhanced fast and slow light in a spinning optomechanical system

We investigate the properties of the optical output fields in a spinning optomechanical system under the condition of optomechanically induced transparency (OMIT), where the cavity is optically driven by a strong pump field and a weak probe field and the mechanical resonator is driven by a coherent...
