Abstract

Abstract: The vacuum Rabi splitting and Kerr effect are investigated theoretically in a hybrid spin–magnon–photon system, where the nitrogen‐vacancy center in diamond driven by two light fields is coupled to a spherical micromagnet embedded in a superconducting coplanar waveguide resonator. The results indicate that the phenomenon of the Mollow triplet and vacuum Rabi splitting can appear by controlling the spin–magnon coupling and magnon–photon coupling. It is shown that the probe absorption spectrum can be adjusted effectively via the pump frequency detuning. Moreover, it is demonstrated that the optical Kerr effect can be tuned by changing the Rabi frequency. This work may provide a possibility for the applications in quantum information processing and quantum sensing of magnetic signal. Abstract : The vacuum Rabi splitting and Kerr effect are explored in a hybrid spin–magnon–photon system. The absorption spectrum can be modulated by adjusting the spin–magnon coupling, the magnon–photon coupling, and the pump frequency detuning, respectively. Further, a method to design a nonlinear Kerr switch is proposed.
