    "abstract": "Here the ionization and high harmonic generation in Hydrogen and Helium by\nusing quantum (hydrodynamic) trajectories is analyzed theoretically. The\nquantum trajectories allow a self-contained treatment of the electron exchange\nand correlation effects without introducing ad hoc potentials into the\nSchrodinger equation. Our approach predicts the correct high harmonic spectra\nand the attosecond pulses generated by the Helium atom beyond the single active\nelectron approximation. It can be used to study complex multi-electron systems\nand their interaction with laser field of both high and low intensity.",
