Abstract

A nonreciprocal phonon laser in a spinning microwave magnomechanical system is proposed. The system consists of a spinning microwave resonator coupled with an yttrium iron garnet sphere. The Fizeau light-dragging effect caused by the spinning of the resonator leads to a significant difference in the mechanical gain and the threshold power for driving the resonator from the opposite directions, which results in a nonreciprocal phonon laser. The nonreciprocal phonon laser is highly tunable by the spinning speed and direction of the resonator. These results provide an experimentally feasible approach for exploring various nonreciprocal effects in cavity magnomechanical systems, and may find applications in photon, magnon, and phonon manipulations in many-body coupled systems.
