研究经历:

中国科学技术大学,近代物理系
博士研究生,导师:陈向军 教授 2013 年 9 月 – 2018 年 12 月
1. 发展了一套全新的多中心三扭曲波方法,编写了相关的代码,成功用于研究低能电子与分子体系的碰撞单电离问题,并在原子体系中得到了验证。该方法不仅仅限于低能碰撞计算,有望成为一种处理电子与原子分子碰撞单电离过程的一般性的经典方法;
2. 将已有的多中心扭曲波理论计算方法成功应用于研究中高能电子与 CH4, N2O 分子体系的碰撞单电离截面问题,得到了与实验数据较为符合的结果;
3. 利用 ADMP 以及 BOMD 分子动力学方法研究了室温下基态 CO23+,OCS2+离子电离解离机制,通过模拟解离过程中离子碎片的动量,初步理解了顺序以及非顺序解离的超快动力学过程。模拟得到的动能释放(KER)与实验数据以及基于第一性原理的精确势能曲线的结果能够很好的符合。

1. 继续发展多中心三扭曲波理论计算方法,优化程序结构,初步解决了分子体系电子动量谱学中扭曲波效应的理论计算问题,并成功应用于 O2分子的电子动量谱中。该方法有望成为一种处理原子分子体系电子动量谱中扭曲波效应的一般方法;
2. 利用已发展的多中心扭曲波方法,成功应用于共面非对称几何条件下的电子与生物大分子(THF, THFA 等等)碰撞的单电离截面计算,并对生物体系(例如 DNA 分子)的辐射电离损伤机制提供一定的理论基础;
3. 在已有的多中心扭曲波方法基础上发展了一套 Twisted-electron 与原子分子碰撞的单电离截面计算方法,并成功应用于 H2O分子体系中;
4. 目前正在从事神经网络方法在多体物理方面的交叉研究。
