Abstract
We theoretically explore the absorption spectra and Kerr effect of a phonon-spin-magnon hybrid system, in which the nitrogen-vacancy (NV) center is coupled with a yttrium iron garnet (YIG) crystal and a mechanical resonator simultaneously. The results indicate that vacuum Rabi splitting can occur in the absorption spectrum by modulating the coupling strength between the YIG sphere and the NV center. We show the vacuum Rabi splitting and the transparency based on mechanically induced coherent population oscillation (MICPO) to be adjusted by the decay rate of the YIG sphere and the mechanical resonator, respectively. Moreover, it is indicated the absorption spectra can be flexibly tuned by changing the frequency tuning of the spin-pump field. Furthermore, the nonlinear Kerr effect is controllable via varying the Rabi frequency. The study could provide a way for general applications in quantum computing devices and quantum information processing.
