Identifying Mechanism of Energy-Resolved Attoclock

Jia'nan Wu, Shiqi Shen, Jiayin Che +4

We study above-threshold ionization (ATI) of atoms in strong elliptical laser fields numerically and analytically. Recent benchmark experiments for H showed that the attoclock offs…

A Coulomb-included model for high-order harmonic generation from atoms

Yigen Peng, Jiayin Che, Ruihua Xu +3

In strong laser-atom interactions, the Coulomb potential can affect the trajectories of rescattering electron in high-order harmonic generation (HHG). Here, by constructing a semi-…

Response time of photoemission at quantum-classic boundary

C. Chen, J. Y. Che, W. Y. Li +6

The response time of the electron to light in photoemission is difficult to define and measure. Tunneling ionization of atoms, a strong-laser-induced photoemission process, provide…
