• Abstract summary: 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.

• 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.

  We find that the maximum entanglement between detectors does not exhibit a strict monotonic dependence on detector acceleration. Novelly, our findings indicate the absence of a strong anti-Unruh effect in (3+1)-dimensional massive scalar fields.

  We investigate the effects of relative motion on entanglement harvesting by considering a pair of Unruh-Dewitt detectors moving at arbitrary, but independent, velocities. We find that the Negativity is a function of the relative velocity of the detectors, as well as their energy gaps and minimal separation.

• The Unruh effect in slow motion [0.0]
  We show in what regimes the probe forgets' that it is traversing cavities and thermalizes to a temperature proportional to its acceleration. We analyze in detail how this thermalization relates to the renowned Unruh effect. We propose an experimental testbed for the direct detection of the Unruh effect at relatively low probe speeds and accelerations.
