Abstract
The electron nondipole dynamics in tunneling ionization in an elliptically polarized laser field is investigated theoretically using a relativistic Coulomb-corrected strong-field approximation (SFA) based on the eikonal approximation of the Klein-Gordon equation. We calculate attoclock angle-resolved light-front momentum distributions at different ellipticities of the laser field in quasistatic and nonadiabatic regimes and analyze them with an improved simple man's model. The nondipole correlations between longitudinal and transverse momentum components are examined. Deviations of the nondipole photoelectron momentum distribution calculated via SFA with respect to the available experimental results as well as with the improved simple man's model are discussed and interpreted in terms of nonadiabatic as well as Coulomb effects in the continuum and under the barrier. The favorable prospects of an experimental observation are discussed.
