Abstract

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 $g^{(2)} (0) ≃ 0$ 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.

带有嵌入式自旋三重子的混合光机械系统中的非常规光子阻断技术

这项研究调查了具有嵌入式自旋三重态的混合光机械系统中的非常规光子阻滞。发射器产生的挤压量子波动与驱动激光器产生的相干分数之间的自同调干扰导致双光子抑制。相关器方程的分析解和主方程的数值模拟显示，调制机械耗散在实现强单光子阻断中起着至关重要的作用。与传统的腔体光机械系统相比，弱单光子光机械耦合可以实现二阶相关函数。通过结合非常规和常规反束，混合系统实现了最大光子群、双光子干扰和高阶相关性抑制的趋同。此外，还研究了热噪声对光子封锁的影响，证明在声子-自旋耦合较弱的情况下，二阶相关性具有更强的鲁棒性。
