Nonreciprocal unconventional magnon blockade in nonlinear cavity electromagnonical system
We propose an effective scheme to predict nonreciprocal unconventional magnon blockade in a hybrid system composed of a rotating pump cavity, a signal cavity and a yttrium iron-garnet (YIG) sphere. The two cavities interact nonlinearly, and meanwhile, the signal cavity couples to magnon in the YIG sphere via magnetic dipole interaction. Based on the dispersive couplings between two cavities and between the signal cavity and magnon, the indirect nonlinear interaction is established between the pump cavity and magnon modes, which plays an important role in the generation of magnon blockade. The system exhibits nonreciprocal unconventional magnon blockade phenomenon when the pump cavity is driven from clockwise or counterclockwise directions. These phenomena occur in weak coupling and driving regimes, which could relax the requirements of the system parameters and may have potential applications in quantum information processing in hybrid systems.
