• Abstract: We present a method for relating the transition rate of an accelerated Unruh-deWitt detector to the rate of the same detector when stationary in Minkowski space. Furthermore, we show that when using the detector as a model for decay, its transition rate can be related directly to the decay rate obtained from QFT. Combined this provides a straightforward method for calculating the decay rate of accelerated particles to first order in the coupling constants.

• Uniformly accelerated quantum counting detector in Minkowski and Fulling vacuum states [0.0]
  We discuss the process of measurements by a detector in an uniformly accelerated rectilinear motion, interacting linearly with a massive scalar field. For the massless case, we obtain that the transition probability rate of the detector in the far future is tantamount to the analogous quantity for the detector at rest in a non-inertial reference frame.

  We study the effects of motion for an Unruh-DeWitt detector, modeled as a two-level system, on the amount of coherence extracted. We observe that compared to a detector at rest, for certain values of the initial energy of the field and the interaction duration, the amount is larger for both a detector moving with a constant speed or uniform acceleration.
