论文摘要
从时间依赖性schrödinger方程(TDSE)的数值解直接提取的光离子化振幅的短时过滤用于识别在强场中形成光电光谱的显性途径。因此,可以克服TDSE求解器的“黑盒性质”,而可以测试和改进基于强场上近似的半古典方法,例如,更简单的方法,例如,半经典的方法。该方法还允许抑制通常在实验中被洗净的途径之间的循环间量子干扰。
Short-time filtering of the photoionization amplitude extracted straight from the numerical solution of the time-dependent Schrödinger equation (TDSE) is used to identify dominant pathways that form photoelectron spectra in strong fields. Thereby, the "black-box nature" of TDSE solvers only giving the final spectrum is overcome, and simpler approaches, e.g., semi-classical based on the strong-field approximation, can be tested and improved. The approach also allows to suppress intercycle quantum interference between pathways removing patterns that are usually washed out in experiments.
