Ramsey interferometry as a witness of acceleration radiation

We adapt a typical Ramsey interferometer by inserting a linear accelerator capable of accelerating an atom inside a single-mode cavity. We demonstrate that this simple scheme allows us to estimate the effects of acceleration radiation via interferometric visibility. By using a Rydberg-like atom, our...

Description
Summary:We adapt a typical Ramsey interferometer by inserting a linear accelerator capable of accelerating an atom inside a single-mode cavity. We demonstrate that this simple scheme allows us to estimate the effects of acceleration radiation via interferometric visibility. By using a Rydberg-like atom, our results suggest that, for the transition regime of the order of GHz and interaction time of 1 ns, acceleration radiation effects can be observable for accelerations as low as 1017 m/s2. •Accelerating Rydberg-like atoms inside the cavity.•Acceleration radiation and the Fulling–Davies–Unruh effect.•Ramsey interferometry and interferometric fringe visibility.•Finite-time corrections to the transition probability.
