Analysis of strong-field ionization via a Bohmian Mechanics approach

We employ Bohmian Mechanics to investigate the strong-field ionization of atomic hydrogen in an ultrashort infrared pulse. The streamlines of the probability current are computed and allow us to obtain quantum trajectories providing insights into the strong-field ionization process. In particular, we study the transition from the multi-photon to the tunneling regime and interpret the main features of the asymptotic electron momentum distribution.
