Achieving Strong Magnon Blockade through Magnon Squeezing in a Cavity Magnetomechanical System

A scheme that harnesses magnon squeezing under weak pump driving within a cavity magnomechanical system to achieve a robust magnon (photon) blockade is proposed. Through meticulous analytical calculations of optimal parametric gain and detuning values, the objective is to enhance the second‐order correlation function. The findings demonstrate a substantial magnon blockade effect under ideal conditions, accompanied by a simultaneous photon blockade effect. Impressively, both numerical and analytical results are found to be in complete accord, providing robust validation for the consistency of the findings. It is anticipated that the proposed scheme will serve as a pioneering approach toward the practical realization of magnon (photon) blockade in experimental cavity magnomechanical systems. This paper presents the magnon–photon blockade effect within a hybrid optomagnomechanical system. It combines optics, magnetics, and mechanics to study how the interaction between magnons and photons can be controlled. The focus lies on investigating magnon squeezing under weak pump driving conditions and analyzing the second‐order correlation function of the optomagnomechanical system, which could have implications for various applications in quantum information processing and computing.
