Abstract: We propose to achieve and enhance the unconventional magnon blockade effect, based on a quantum destructive interference mechanism in an optomechanicalmagnetic system composed of a rotating cavity and a yttrium irongarnet (YIG) sphere. We introduce a degenerate parametric amplifier and derive the optimal parametric gain and phase to achieve magnon blockade analytically. By tuning the system parameters (weak coupling) and the driving detuning of the cavity and magnon modes, we achieve the smallest second-order magnon correlation function. The optomechanical cavity couples to the YIG sphere by magnetic dipole interaction. We achieve unconventional magnon blockade effects when the cavity is driven from a clockwise or counterclockwise direction. We introduce a new feature that combines the impact of destructive interference and energy-level anharmonicity to achieve magnon blockade. The equal-time second-order magnon correlation avoids time delay and rapid oscillation. In the input end of the system, two photons drive, and complete quantum destructive interference. This study opens a new window for physical applications, including the generation of single magnon sources, Quantum sensing, and Quantum simulation. Experimentally, we can control quantum noise and amplify the signal using parametric amplification.
