Geometric phase assisted observation of noninertial cavity-QED effects

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. Because of its sensitive nature, the geometric phase is instrumental in capturing weak effects such as the acceleration-induced noninertial 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 noninertial 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, noninertial 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 similar to 10(7) m/s(2) which is experimentally feasible.

Automated summary

This paper investigates the geometric phase phenomenon in quantum systems and discusses the possibility of isolating or enhancing geometric phase using noninertial means inside an electromagnetic cavity. The results show that the accumulative nature of the geometric phase facilitates the experimental observation of noninertial contributions, and it demonstrates the feasibility of detecting experimentally measurable geometric phases under accelerations.
