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 electrons to light in strong-field ionization of polar molecules
Jiayin Che, Sheng Ye, Shiqi Shen +2
We study tunneling ionization of HeH+ in strong elliptical laser fields numerically and analytically. The calculated photoelectron momentum distribution (PMD) show two different of…
