Abstract

The phenomenon of photon and magnon blockade, which yields single photon and single magnon source, has been becoming a novel platform for realizing great applications in the quantum information processing. Here, in this study, the dynamics of photon and magnon is studied, and the tunable photon and magnon blockade is found in a hybrid optomagnonic microcavity. Specifically, the simultaneous blockade of photon and magnon is observed in the optomagnonic system consisting of a YIG sphere within a two-mode microwave cavity in the presence of photonic and magnonic Kerr nonlinearity, by applying the second-order correlation function. The numerical results exhibit strong photon and magnon blockade and indicate that the amount of antibunching, emerging from the considered magnonic system, can appropriately be tuned by choosing the phonon–magnon coupling strength, and photonic and magnonic Kerr nonlinearity. It is worth mentioning that the phenomenon of complete photon and magnon blockade appears, both simultaneously and separately.
