Quantum Measurements in a Finite Space–Time Domain
In this paper, we discuss the quantum Unruh⁻DeWitt detector, which couples to the field bath for a finite amount of its proper time. It is demonstrated that due to the renormalization procedure, a new dimensionful parameter appears, having the meaning of a detector’s recovery pro...
