论文摘要
当量子系统的状态围绕参数空间中的封闭轨迹围绕时，量子系统的状态将获取一个称为几何相的相位因子，这仅取决于参数空间的几何形状。由于其敏感性，几何阶段在捕获弱效应（例如加速诱导的非惯性量子场理论效应）方面具有重要作用。在本文中，我们研究了电磁腔内圆形旋转检测器的几何相响应。使用腔体，可以从相对于惯性贡献中分离出对几何阶段的非惯性贡献。我们表明，几何阶段的累积性质可能有助于对所得的，否则微弱的，非惯性的贡献对腔内修饰的场相关性的贡献。具体而言，我们表明该原子以$ \ sim 10^{7} $ m/s $^2 $的加速度获得实验可检测到的几何阶段，这在实验上是可行的。
The state of a quantum system acquires a phase factor, called the geometric phase, when taken around a closed trajectory in the parameter space, which depends only on the geometry of the parameter space. Due to its sensitive nature, the geometric phase is instrumental in capturing weak effects such as the acceleration-induced non-inertial quantum field theoretic effects. In this paper, we study the geometric phase response of a circularly rotating detector inside an electromagnetic cavity. Using the cavity, the non-inertial contribution to the geometric phase can be isolated from or strengthened relative to the inertial contribution. We show that the accumulative nature of the geometric phase may facilitate the experimental observation of the resulting, otherwise feeble, non-inertial contribution to the modified field correlations inside the cavity. Specifically, we show that the atom acquires an experimentally detectable geometric phase at accelerations of the order of $\sim 10^{7}$ m/s$^2$ which is experimentally feasible.
