Abstract

In this paper, we optimize photon blockade in a cavity magnomechanical system using feedback by introducing optimized values for the phase and magnetic field coupling strength at each drive frequency. It is shown that the computed values significantly reduce the photon second-order correlation function in the dynamic Schrodinger equation. The Radau method, an implicit Runge-Kutta method, has been employed, which provides more accurate results. Furthermore, we demonstrate that a frequency detuning between the magnon and photon can result in deep values of photon blockade. Utilizing these optimized parameters outperforms scenarios that rely on constant, non-optimized values. This approach provides strong potential for applications in quantum sensing and quantum computation.
