Decoherence as Detector of the Unruh Effect
arXiv:2003.05014 · doi:10.1103/PhysRevResearch.2.043230
Abstract
We propose a new type of the Unruh-DeWitt detector which measures the decoherence of the reduced density matrix of the detector interacting with the massless quantum scalar field. We find that the decoherence decay rates are different in the inertial and accelerated reference frames. We show that the exponential phase decay can be observed for relatively low accelerations, that can significantly improve the conditions for measuring the Unruh effect.
