报告内容简介：

Charge migration (CM) refers to the rapid movement of a positively charged hole in a molecule following localized ionization or excitation, and typically takes place on the attosecond or few-femtosecond time scale, and it is considered a precursor to more permanent structural or chemical changes. In this talk, I will focus on our recent theory efforts on how to characterize and probe charge migration in molecules. In particular, I will discuss on questions relevant to successful CM experiments, such as which molecules best support CM and to what extent the dynamics of CM are influenced by how it is initiated, and I will show how to probe CM using high-harmonic sideband spectroscopy.
