This study investigates the various macroscopic quantum coherences in a spinning whispering-gallery-mode resonator system, revealing that the one-mode quantum coherences play a main role in two- and three-mode quantum coherences. The research also shows that quantum coherences in the spinning system are nonreciprocal, increasing monotonically with the rotating angular velocity when the driving direction of the laser field aligns with the rotation direction of the resonator.
We investigate the various macroscopic quantum coherences including one-, two- and three-mode ones in a spinning whispering-gallery-mode resonator system and examine how the input laser power, the coupling strength of the optical modes, the rotating angular velocity, and the optical and mechanical decay rates influence them. We find in two- and three-mode quantum coherences the one-mode quantum coherences play a main role. We also find that the quantum coherences in the spinning system are nonreciprocal, they monotonically increase as the rotating angular velocity increases when the driving direction of the laser field is consistent with the rotation direction of the resonator, otherwise they reduce monotonically.
