We study ionization of aligned H in strong elliptically-polarized laser fields numerically and analytically. The calculated offset angle in photoelectron momentum distributio…
Roles of laser ellipticity in attoclock
J. Y. Che, J. Y. Huang, F. B. Zhang +3
We study ionization of atoms in strong elliptically-polarized laser fields numerically and analytically. We focus on effects of laser ellipticity on the offset angle in photoelectr…
Coulomb scattering inducing time lag in strong-field tunneling ionization
Y. G. Peng, J. Y. Che, C. Chen +2
We study ionization of atoms in strong elliptically-polarized laser fields. We focus on the physical origin of the offset angle in the photoelectron momentum distribution and its p…
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…
Strong-field response time and its implications on attosecond measurement
Chao Chen, Jiayin Che, Shang Wang +2
To measure and control the electron motion in atoms and molecules by the strong laser field on the attosecond time scale is one of the research frontiers of atomic and molecular ph…
Measuring Coulomb-Induced Ionization Time Lag with a Calibrated Attoclock
J. Y. Che, C. Chen, S. Wang +2
Electrons in atoms and molecules can not react immediately to the action of intense laser field. A time lag (about 100 attoseconds) between instants of the field maximum and the io…
Characterizing Sub-Cycle Electron Dynamics of Polar Molecules by Asymmetry in Photoelectron Momentum Distributions
Jia-Yin Che, Chao Chen, Shang Wang +2
Strong-field ionization of polar molecules contains rich dynamical processes such as tunneling, excitation, and Stark shift. These processes occur on a sub-cycle time scale and are…
Tracing origins of asymmetric momentum distribution for polar molecules in strong linearly-polarized laser fields
S. Wang, J. Y. Che, C. Chen +2
We study the ionization dynamics of oriented HeH in strong linearly-polarized laser fields by numerically solving the time-dependent Schrödinger equation. The calculated photoe…
Coulomb-induced ionization time lag after electrons tunnel out of a barrier
Y. J. Chen, X. J. Xie, C. Chen +2
After electrons tunnel out of a laser-Coulomb-formed barrier, %formed by the strong laser field and the atomic Coulomb potential, the movement of the tunneling electron can be affe…
Atomic Bright Soliton Interferometry
Li-Chen Zhao, Guo-Guo Xin, Zhan-Ying Yang +1
The properties of nonlinear interference pattern between atomic bright solitons are characterized analytically, with the aid of exact solutions of dynamical equation in mean-field…
