Outline of Final Research Achievements

(1) Based on our theoretical simulations, we have discovered the mechanism of the atomic ionization process in the strong laser field, by decomposing the contributions of half-cycle ionization and the interference of multi-cycle. (2) Based on the results of (1), we investigated the control mechanism of atomic, molecular photo-absorption process by intense laser. (3) Based on real space, real time density functional theory simulation, we discovered the mechanism of how an insulator can become a conductor in the femtosecond time domain by strong field.
