Usual uniformly accelerated frame, in Dray–’t Hooft spacetime, does not see the any quantum imprint on Unruh effect due to localized 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, cannot 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 analyze for a null like trajectory along which the detector is moving.

冲击探测器中的冲击波量子存储器

在 Dray-'t Hooft 时空中，通常的均匀加速框架没有看到由于 Minkowski 时空中的局部冲击波而对 Unruh 效应产生任何量子印记。在这里，我们认为这种不出现量子记忆是特定于那些在其轨迹中不包含波存在的特定观察者。事实上，与受冲击影响的框架相关联的检测器在其响应方面并非微不足道。我们明确地表明，后一种类型的框架检测到冲击波 Minkowski 真空中的粒子，这是冲击的影响。因此，就 Dray-'t Hooft 时空而言，这种量子记忆对于特定类别的观察者来说是非常特殊的。我们分析检测器沿其移动的类似零点的轨迹。
