Theoretical studies on photo-excitation processes of molecular ions generated in intense laser fields

在上一学年模拟结果的基础上，进一步研究了电离时间问题，使整个激光脉冲过程中的电离过程都能被考虑在内。其次，我们在量子计算机上发展了基于突然开启模型的电离后激发过程的量子模拟算法。第三，利用本人在过去一个财政年度发展的分子系统电离和激发的理论方法，从理论上研究了分子在极紫外阿秒激光脉冲作用下的电离和激发过程。

Based on the results of the simulations performed in the past academic year, the ionization timing issue is further investigated, so that all the ionization processes induced throughout the entire laser pulse can be included.Secondly, we developed quantum algorithms for simulating the post-ionization excitation process using the sudden turn-on model on a quantum computer. Both simulator testing and real machine IBM-Q and continuum testing are done.Thirdly, by taking advantage of the theoretical methods I developed in the past fiscal year on the ionization and excitation of molecular systems, I investigated theoretically how molecules are ionized and excited by an attosecond laser pulse whose wavelength is in the extreme ultraviolet region.
