Ab Initio Electronic Dynamics of H$_{2}$ in Strong Attosecond Laser Field

Using Multi-Configuration Time-Dependent Hartree Fock with adaptive multiresolution methods and self-adaptive time propagation techniques with controlled accuracy we analyze ionization yields, electron spectra and high-harmonic radiation of a hydrogen molecule in an attosecond strong laser pulse. We follow single- and two-electron dynamics of the process of ionization during a single field cycle, including rescattering imaging of a molecular orbital and the scattering production of harmonics.
