Electron momentum distributions from H(1s) ionized by circularly polarized laser pulses

Recently a 3d computer code for the time-dependent Schr\"odinger equation was developed to deal with the problem of high harmonic generation in orthogonal two-color laser fields [1]. This code has been extended to collect the ionized electron flux in the outer spatial region and to implement a Volkov-type momentum space evolution. This code is used to analyze H(1s) atoms exposed to several-cycle circularly polarized laser pulses in the $10^{14}$ W cm$^{-2}$ intensity regime. The main interest of the work is to investigate systematics in the electron momentum distributions, and the role of Coulomb interactions, in particular. \\[4pt] [1] M. Murakami, O.Korobkin, M.
