| Outline of Final Research Achievements |
We have analyzed multielectron dynamics in molecules under intense laser fields calculated with ab initio methods. By analyzing the enhanced ionization of hydrogen molecules using Bohmian trajectories, we have revealed, contrary to what was previously believed, that the ejection from the up-field and down-field cores are comparable. Moreover, we have numerically implemented multiconfiguration time-dependent Hartree-Fock method for molecules, we have successfully simulated high-harmonic generation from a water molecule and charge migration in LiH and water molecules, for the first time.
