Measuring acceleration using the Purcell effect

TL;DR

This paper proposes a method to measure acceleration by using a two-level atom in a cavity, exploiting the Purcell effect to detect changes in transition probability caused by acceleration.

Contribution

It introduces a novel approach to measure acceleration with a two-level atom-cavity system by analyzing the Purcell effect's sensitivity to acceleration.

Findings

Transition probability varies with acceleration.

Optimal atom position and frequency enhance sensitivity.

Method provides a new quantum sensing technique for acceleration.

Abstract

We show that a two-level atom resonantly coupled to one of the modes of a cavity field can be used as a sensitive tool to measure the proper acceleration of a combined atom-cavity system. To achieve it we investigate the relation between the transition probability of a two-level atom placed within an ideal cavity and study how it is affected by the acceleration of the whole. We indicate how to choose the position of the atom as well as its characteristic frequency in order to maximize the sensitivity to acceleration.
