Navdeep Arya - Unruh effect inside a cylindrical cavity

Abstract: The Unruh effect states that the transition rates of a uniformly accelerated detector in the inertial vacuum have a thermal character at a temperature proportional to the detector's acceleration. Numerous proposals studying different properties of the accelerated detector under varied settings still await fruition as the signal of interest is generally very weak.
We will discuss the Unruh effect inside a cylindrical cavity, with special emphasis on strategies that might help us resolve it better. We will discuss the transition rates and radiative energy shift of an atom uniformly accelerated along the axis of the cavity. We will argue that the requirement of large acceleration for an appreciable non-inertial contribution to these properties can be traded for a better precision in cavity design. We will conclude with a brief discussion on the possibility of selective super-radiant enhancement of the Unruh signal.
