摘要
A fully quantum procedure, based on the numerical solution of the time-dependent Schrodinger equation (TDSE) with two spatial dimensions for every electron, is developed to study the attosecond double-ionization (DI) dynamics from aligned H-2 molecules in strong laser fields. Our simulations are able to reproduce the orientation dependence of DI, as observed for N-2 in experiments [D. Zeidler et al., Phys. Rev. Lett. 95, 203003 (2005)]. Our TDSE analyses reveal the important roles of the lateral motion of the electron and two-center interference in the orientation-dependent DI. Our results give suggestions on the ultrafast probing of the dynamics of DI from aligned molecules.
