abstract
We show that a detector acquires a Berry phase due to its motion in spacetime. The phase is different in the inertial and accelerated case as a direct consequence of the Unruh effect. We exploit this fact to design a novel method to measure the Unruh effect. Surprisingly, the effect is detectable for accelerations 10^9 times smaller than previous proposals sustained only for times of nanoseconds.

Moderate acceleration of an Unruh-DeWitt detector in a cylindrical cavity suppresses decoherence more effectively than the inertial case by smearing resonant modes and replacing off-resonant decay with oscillations.
Proposes using split laser beams on a pancake BEC and heterodyning to make the response function of a superposed Unruh-deWitt detector appear in the difference photocurrent power spectrum, with SNR estimates using squeezed light.
