On the Dynamics of Unruh-DeWitt Detectors in Rotating Frames

Abstract

In this work, the dynamics of one and two rotating Unruh-DeWitt detectors is presented. The rotating vacuum is a subject of great discussion because, even though Bogoliubov transformations show that this vacuum should be identical to the inertial vacuum, the field’s correlation function indicates otherwise. Thus, describing the dynamics of a single detector helps establish whether rotation can lead to spontaneous excitation from the vacuum. It has been shown that vacuum interaction with a system can promote non-local correlations between its constituents. Hence, an analysis of a system with two rotating detectors in different positions is conducted, and their dynamics are explored, with a focus on entanglement harvesting and degradation.
