Recollision of excited electron in below-threshold nonsequential double ionization
Xiaolei Hao, Yuxing Bai, Chan Li +5
Consensus has been reached that recollision, as the most important post-tunneling process, is responsible for nonsequential double ionization process in intense infrared laser fiel…
Decoding electron tunnelling delay time by embracing wave-particle duality
Chuncheng Wang, Xiaokai Li, Xiwang Liu +7
Tunnelling lies at the heart of quantum mechanics and is a fundamental process in attosecond science, molecular biology, and quantum devices. Whether tunnelling takes time and how…
Effect of Stark shift on low-energy interference structure in strong-field ionization
Weifeng Yang, Jie Li, Wenbin Jia +5
An improved quantum trajectory Monte Carlo method involving the Stark shift of the initial state, Coulomb potential, and multielectron polarization-induced dipole potential is used…
Deep Learning for Feynman's Path Integral in Strong-Field Time-Dependent Dynamics
Xiwang Liu, Guojun Zhang, Jie Li +6
Feynman's path integral approach is to sum over all possible spatio-temporal paths to reproduce the quantum wave function and the corresponding time evolution, which has enormous p…
Low-Energy Interference Structure with Attosecond Temporal Resolution
Xiaohong Song, Wenbin Jia, Xiwang Liu +7
Accessing precisely to the phase variation of electronic wave-packet (EWP) provides unprecedented spatiotemporal information of microworld. A radial interference pattern at near-ze…
Accuracy of the semiclassical picture of photoionization in intense laser fields
Li Guo, Shilin Hu, Mingqing Liu +7
In the semiclassical picture of photoionization process in intense laser fields, the ionization rate solely depends on the amplitude of the electric field and the final photoelectr…
