约束在环中的原子超流体为量子化循环提供了一个非凡的范例。最近，一种基于腔光力学的技术被提出[Kumar， Phys]。用于传感和操纵玻色子环凝聚体的旋转，以最小的破坏，实时，在现场。在这里，我们从理论上研究了其他相干干涉效应，可以由所提出的配置支持。具体来说，在强控制光束存在的情况下，我们分析了原子旋转对弱探测激光通过含有环状凝聚物的腔的透射光谱的影响。我们详细研究了由此产生的窄探头传输曲线和群延迟，并表明它们可以通过持续电流进行调谐。我们的研究结果探索了旋转物质波的一个方面，并与原子电子学、传感和信息处理等应用相关。
Atomic superfluids confined in a ring provide a remarkable paradigm for quantized circulation. Very recently, a technique based on cavity optomechanics has been proposed [Kumar , Phys. Rev. Lett. 127, 113601 (2021)10.1103/PhysRevLett.127.113601] for sensing and manipulating the rotation of a bosonic ring condensate with minimal destruction,in situand in real time. Here, we theoretically investigate other coherent interference effects that can be supported by the proposed configuration. Specifically, in the presence of a strong control beam, we analyze the influence of atomic rotation on the transmission spectrum of a weak probe laser through a cavity containing a ring condensate. We present a detailed study of the resulting narrow probe transmission profiles and group delay and show that they can be tuned by means of persistent currents. Our results explore a facet of rotating matter waves and are relevant to applications such as atomtronics, sensing, and information processing.
