Shock wave quantum memory in shocked detector

Usual uniformly accelerated frame, in Dray–’t Hooft spacetime, does not see the any quantum imprint on Unruh effect due to localized shock wave Minkowski spacetime. Here, we argue that such non-appearance of memory is specific those particular observers which do incorporate presence their trajectory. In fact, a detector, associated with frame affected by shock, cannot be trivial terms its response. We explicitly show later type detects particle vacuum shock. Therefore, this very special class as far spacetime concerned. analyze for null like trajectory along detector moving.
