摘要：
By incorporating the quantum effects and the Coulomb interaction between the first ionized electron and the residual ion in a uniform theory, the Coulomb-corrected quantum-trajectories (CCQT) method is developed to describe the recollision-impact ionization (RII) process in nonsequential double ionization of atoms in intense laser field. The results simulated by CCQT are found to be in better agreement with the experimental results, compared with those calculated by the classical-trajectory Monte Carlo (CTMC) and strong-field approximation (SFA) methods. Considering its advantage of small computational cost and back-trajectory analysis, the CCQT method will be an efficient theoretical tool to quantitatively investigate the underlying physics of the complex and coherent multielectron dynamics in intense laser field.
