Abstract: Abstract We investigate the features of electron returning trajectories in recollision-induced nonsequential double ionization by intense circularly polarized laser pulses within a classical ensemble model. We find typical two-dimensional returning trajectories of the first ionized… read more here.

Abstract: We investigate laser-induced nonsequential double ionization with linearly polarized bichromatic fields, focusing on the recollision-excitation with subsequent ionization (RESI) mechanism. Using the strong-field approximation, we assess how the symmetries of the field influence the dominant… read more here.

DOI: 10.1103/physrevlett.121.263203
Abstract: At intensities below the recollision threshold, we show that recollision-induced excitation with one electron escaping fast after recollision and the other electron escaping with a time delay via a Coulomb slingshot motion is one of… read more here.

Abstract: Nonsequential double ionization (NSDI) of Argon atoms by counter-rotating two-color elliptically polarized (TCEP) fields is investigated with a three-dimensional classical ensemble model. Different from two-color circularly polarized fields, the combined electric field in TCEP pulses… read more here.
