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

在过去一学年的模拟结果的基础上，进一步研究了电离时间问题，以便包括整个激光脉冲中诱导的所有电离过程。其次，我们利用量子计算机上的突然开启模型，开发了模拟电离后激发过程的量子算法。进行了仿真测试、IBM-Q实机测试和连续体测试。第三，利用我在上一财政年度开发的关于分子系统电离和激发的理论方法，我从理论上研究了波长在极紫外区的阿秒激光脉冲是如何电离和激发分子的。

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.
