论文摘要
该论文致力于通过电磁脉冲对量子振荡器激发的时间依赖性的理论研究，用于脉冲中磁场振幅的任意值。我们考虑谐波振荡器，没有放松和固定状态之间的激发。激发量子状态作为时间功能的一般公式是根据电磁脉冲领域中相关经典振荡器的即时能量得出的。因此，已经确定量子振荡器激发的时间依赖性完全由相关的经典振荡器在给定时间时刻的能量确定。使用量子振荡器激发的衍生表达时间依赖性进行详细研究，包括来自基态的总激发，激发状态的激发，总的激发概率和相应的激发光谱。
The paper is devoted to the theoretical investigation of time dependences of quantum oscillator excitation by electromagnetic pulses for arbitrary values of field amplitude in the pulse. We consider the harmonic oscillator without relaxation and excitation between stationary states. The general formula for excitation of quantum states as function of time is derived in terms of instant energy of associated classical oscillator in the field of electromagnetic pulse. Thus, it is established that time dependence of quantum oscillator excitation is completely determined by the energy of the associated classical oscillator at given moment of time. Using derived expression time dependence of quantum oscillator excitation is investigated in details including total excitation from ground state, excitation from excited states, total excitation probability and corresponding excitation spectra.
