Nonperturbative Calculation

This work deals with the fundamental problem of the behavior of the two-electron atom under intense laser fields. We present a broad scope of calculations and results and, we believe, the first ATI spectrum, in He and Mg atom, beyond the single active electron model in a fully time-dependent nonperturbative calculation. For He, we perform calculations both on a two-electron basis with configuration interaction where both electrons are allowed to be excited, and on a frozen core basis. The comparison is a direct measure of the effect of correlation under strong fields. The results for Mg shows that the method also opens a way to the study of atoms with much stronger electron correlation in intense laser fields.

In this study, we present the results of a theoretical study of the time-dependent angular momentum equation for low-symmetry aromatic ring molecule combine with vibrational effect using two linearly polarized UV laser. We consider the vibrational effect on Toluene molecule and show how the vibrational effect to change of the oscillation periods of unidirectional angular momentum.
