摘要

摘要原子干涉仪已被证明是精密计量的有力工具。在此，我们提出了一种空腔辅助非线性原子干涉仪，它基于被困在光腔中的原子自旋-1玻色-爱因斯坦凝聚态的准周期自旋混合动力学。我们发现，在空腔介导的非线性相互作用下，相位灵敏度可以大大提高。我们仔细研究了编码相位、分裂时间和重组时间对相位灵敏度的影响。此外，我们还证明了系统中的动态相变。在临界点附近，微小的空腔光场变化就能引起原子凝聚物的强烈反应，这可以作为增强传感的新资源。这项工作为空腔增强计量学提供了一个稳健的协议。

Cavity-enhanced metrology in an atomic spin-1 Bose–Einstein condensate

Atom interferometer has been proven to be a powerful tool for precision metrology. Here we propose a cavity-aided nonlinear atom interferometer, based on the quasi-periodic spin mixing dynamics of an atomic spin-1 Bose–Einstein condensate trapped in an optical cavity. We unravel that the phase sensitivity can be greatly enhanced with the cavity-mediated nonlinear interaction. The influence of encoding phase, splitting time and recombining time on phase sensitivity are carefully studied. In addition, we demonstrate a dynamical phase transition in the system. Around the criticality, a small cavity light field variation can arouse a strong response of the atomic condensate, which can serve as a new resource for enhanced sensing. This work provides a robust protocol for cavity-enhanced metrology.
