Shock wave quantum memory in shocked detector
arXiv:2108.01307 · doi:10.1142/S0217732321501868
Abstract
Usual uniformly accelerated frame, in Dray-'t Hooft spacetime, does not see the any quantum imprint on Unruh effect due to localised shock wave in Minkowski spacetime. Here we argue that such non-appearance of quantum memory is specific to those particular observers which do not incorporate the presence of wave in their trajectory. In fact a detector, associated with a frame which is affected by the shock, can not be trivial in terms of its response. We explicitly show that the later type of frame detects particle in the shock wave Minkowski vacuum which is the effect of shock. Therefore this quantum memory is very special to specific class of observers as far as Dray-'t Hooft spacetime is concerned. We analyse for a null like trajectory along which the detector is moving.
