We examine the effect of a frequency-chirped external force field on the final energy that has been absorbed by two classical mechanical oscillators, by quantum mechanical two- and three-level systems, and by electron-positron pairs that were created from the quantum field theoretical Dirac vacuum. By comparing the final dynamical responses to the original force field with that associated with the corresponding time-reversed field, we can test the sensitivity of each of these five systems to the temporal phase information contained in the field. We predict that the linear oscillator, the two-level atom, and the pair-creation process triggered by a spatially homogeneous field are remarkably immune to this phase, whereas the quartic oscillator, the three-level atom, or the pair-creation process caused by a space-time field absorb the provided energy differently depending on the temporal details of the external field.

我们研究了-线性外力场对最终能量的影响,该能量已被两个经典机械振荡器,量子力学两能级和三能级系统以及由量子场产生的电子-正电子对吸收理论狄拉克真空。通过将对原始力场的最终动力响应与与相应的时间反转场相关的动力响应进行比较,我们可以测试这五个系统中的每个对场中包含的时间相位信息的敏感性。我们预测线性振荡器,两能级原子和由空间均匀场触发的成对过程对这一相位具有明显的免疫力,而四阶振荡器,三能级原子,
