“…Subsequently, Liu et al also accomplished the ground-state cooling of the rotating mirror in a double L-G cavity with atomic ensemble [58]. These studies on the ground cooling of the rotating mirror have provided many opportunities to further investigate macroscopic quantum phenomena in rotational cavity optomechanical systems, including bipartite quantum entanglement [57,[60][61][62] and tripartite quantum entanglement [63], macroscopic quantum coherence [64], OMIT phenomena [65][66][67][68][69][70], and its applications for the measurement of orbital angular momentum [65,71,72], higher order sideband generation [73,74] and phase-matching analysis [75]. However, compared to studies on conventional optomechanical systems, the research on the double-OMIT phenomenon in this type of rotating cavity optomechanical system is still essentially very limited.…”

We investigate the optical behavior of a single Laguerre-Gaussian cavity optomechanical system consisting of two mechanically rotating mirrors. We explore the effects of various physical parameters on the double optomechanically induced transparency (OMIT) of the system and provide a detailed explanation of the underlying physical mechanism. We show that the momentum is not the cause of the current double-OMIT phenomena; rather, it results from the orbital angular momentum between the optical field and the rotating mirrors. Additionally, the double-OMIT is simply produced using a single Laguerre-Gaussian cavity optomechanical system rather than by integrating many subsystems or adding the atomic medium as in earlier studies. We also investigate the impact of fast and slow light in this system. Finally, we show that the switching between ultrafast and ultraslow light can be realized by adjusting the angular momentum, which is a new source of regulating fast-slow light.

Enhanced Entanglement and Controlling Quantum Steering in a Laguerre–Gaussian Cavity Optomechanical System with Two Rotating Mirrors

Gaussian quantum steering is a type of quantum correlation in which two entangled states exhibit asymmetry. An efficient theoretical proposal is presented for the control of quantum steering and enhancement of entanglement in a Laguerre-Gaussian (LG) cavity optomechanical system. The system contains two rotating mirrors and a coherently driven optical parametric amplifier (OPA). The numerical results show significantly improved mirror-mirror and mirror-cavity entanglements by controlling the system parameters such as parametric gain, parametric phase, and the frequency of the two rotating mirrors. In addition to bipartite entanglement, our system also exhibits mirror-cavity-mirror tripartite entanglement as well. Another intriguing finding is the control of quantum steering, for which several results were obtained by investigating it for various system parameters. It is shown that the steering directivity is primarily determined by the frequency of two rotating mirrors. Furthermore, for two rotating mirrors, quantum steering is found to be asymmetric both one-way and two-way. Therefore, it can be asserted that the current proposal may help in the understanding of non-local correlations and entanglement verification tasks.
