“…In particular, we have shown that the dispersion curve shows a sharp dispersion change at the dip, which prompted the study of fast-slow light. In general, the phase of output probe field is related to the group delays of the output field and is given by [50][51][52][53][54]…”

“…Moreover, single OMIT and double-OMIT transparency windows have both been investigated in various quantum optomechan-ical systems, such as hybrid optomechanical cavities [35][36][37][38][39][40][41][42] and atomic-media assisted optomechanical systems [43][44][45][46]. OMIT also has significant applications in the generation of fast/slow light [50][51][52][53][54] including light storage [36,55,56] and the precise measurement of a variety of physical quantities such as electrical charge [47], mass sensor [48], and environmental temperature [49].…”

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.

“…Cavity optomechanics is an emerging research area which explores the coherent coupling between the optical mode and the mechanical mode through the radiation pressure of photons trapped inside an optical cavity [1][2][3]. It has also made significant advances in this modern era of quantum technology such as ultrahigh-precision measurement [4], gravitation-wave detection [5], quantum information processing (QIP) [6], non-classical photon statistics [7][8][9][10], quantum entanglement [11][12][13][14][15][16][17][18][19], macroscopic quantum coherence [20][21][22], ground-state cooling of mechanical oscillator [23,24], and optomechanically induced transparency (OMIT) [25][26][27][28][29][30][31][32] including quantum teleportation [33,34] and quantum communication [33][34][35]. Moreover, the measurement of weak forces at the quantum limit of sensitivity is of particular importance [36,37] and also leads to major developments in cavity optomechanical sensors [38,39].…”

The weak force sensing based on a coherent quantum noise cancellation (CQNC) scheme is presented in a hybrid cavity optomechanical system containing a trapped ensemble of ultracold atoms and an optical parametric amplifier (OPA). In the proposed system, the back-action noise can be completely eliminated at all frequencies and through the proper choice of the OPA parameters, and the noise spectral density can also be reduced at lower frequencies. This leads to a significant enhancement in the sensitivity of the cavity optomechanical weak force sensor, and the noise spectral density also surpasses the standard quantum limit (SQL) even for the small input power at the lower detection frequency. Furthermore, the experimental feasibility of this scheme is also briefly discussed. This study can be used for the realization of a force sensor based on hybrid cavity optomechanical systems and for the coherent quantum control in macroscopic systems.

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

et al. 2023

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.
