Unconventional Photon Blockade in a Hybrid Optomechanical System with an Embedded Spin-Triplet
This research investigates the unconventional photon blockade in a hybrid optomechanical system with an embedded spin-triplet state. The self-homodyning interference between squeezed quantum fluctuations produced by the emitter and the coherent fraction from the driving laser results in two-photon suppression. Analytical solutions of the correlator equation and numerical simulations of the master equation reveal that modulated mechanical dissipation plays a crucial role in achieving strong single-photon blockade. In contrast to conventional cavity optomechanical systems, a second-order correlation function of can be achieved with weak single-photon optomechanical coupling. By combining unconventional and conventional antibunching, the hybrid system achieves the convergence of maximal photon population, two-photon interference, and suppression of higher-order correlations. Additionally, the influence of the thermal noise on photon blockade is investigated, demonstrating greater robustness of the second-order correlation under weaker phonon-spin coupling.
