Study of attoclock experiments using Bohmian mechanics

We employ Bohmian mechanics to investigate strong-field ionization in attoclock experiments [1,2]. We consider hydrogen and a short-range Yukawa potential to compute streamlines of the probability current. The obtained trajectories can be used to retrieve physical observables and to improve our understanding of the tunneling dynamics with circular light. In particular, we can look at the spatial origin of the Bohmian trajectories associated with a specific asymptotic photoelectron momentum, as well as the correspondong exit position and velocity. This information provides us with new insights to interpret momentum distributions in the attoclock setup.
