Electron correlation and double ionization of a 1D H2 in an intense laser field

Abstract

Single and double electron ionization probabilities are calculated for a one-dimensional (1D) H2 molecule from the exact numerical solution of the system's time-dependent Schrödinger equation (TDSE) at 800 nm and intensities 1013W cm-2<I<1015 W cm−2. Comparison is made for three electronic states, and of the molecule. Using the exact time-dependent densities of the three states allows for comparison of density functional probabilities obtained from exact one-electron densities with the exact probabilities.
