The research topics I was engaged in during the fiscal year were the following:1) As a continuation of the research from the previous fiscal year, we finalized our work on the photodissociation dynamics of the H_2He+ molecular ion in an intense femtosecond laser pulse, and published our results in a scientific paper.2) Using the theoretical framework we developed in the last fiscal year, which allows for high accuracy, variational simulations of laser induced rovibrational/alignment dynamics of polyatomic molecules, we investigated the laser-induced alignment dynamics of the H_2He+ and H_2O molecules. We published our research results in a scientific paper.3) Using Java and Mathematica programming languages, we developed a cross-platform, user-friendly software named “Laser-induced Alignment and Orientation Simulator” (LAOS), which can be used to simulate the light-induced rotational dynamics of molecules within the rigid rotor approximation. To the best of our knowledge, such software is not yet available, and we believe it will be useful for experimental scientists involved in related research. Publication of the program in a scientific journal is in preparation.4) We started a collaboration with a visiting professor from Bielefeld University, Germany, Prof. Farhad H. M. Faisal, on developing novel theoretical approaches to efficiently simulate strong field ionization in multielectron systems and to investigate the role of electron correlation in the photoionization processes. Our joint work is in progress.

我在财政年度参与的研究主题是以下内容：1）作为上一个财政年度的研究的延续，我们完成了在H_2HE+分子离子的光电解离动力学上的工作，以强烈的femtsopsecteent激光脉冲，并在科学范围内发表了我们的结果。激光诱导的动态/对准动态的模拟我们在科学论文中发表了研究结果。3）使用Java和Mathematica编程语言，我们开发了一种跨平台，用户友好的软件，名为“激光诱导的对齐对齐和方向的对位和方向模拟器”（可以用来模拟旋转的旋转动力学）。据我们所知，此类软件尚不可用，我们认为这对于参与相关研究的实验科学家将很有用。 4）我们与德国比尔雷菲尔德大学（Bielefeld University）的一位访问教授Farhad H. M. Faisal教授开始合作，开发了新型理论方法，以有效地模拟多级电源系统中的强场电离，并研究照相校正过程中电子校正的作用。我们的联合工作正在进行中。
