Abstract: Based on the approach within the single-electron approximation (SEA) frame, we numerically solve the two-dimensional (2D) time-dependent Schr o¨ dinger equation of N2 molecules under co-rotating and counter-rotating circularly polarized attosecond pulses. The vortex structure… read more here.

Abstract: Formation of electron vortices and spirals in photodetachment from the H- anion driven by isolated ultrashort laser pulses of circular polarization or by pairs of such pulses (of either co-rotating or counter-rotating polarizations) are analyzed… read more here.

DOI: 10.3788/col201715.120202
Abstract: The photoionization by two elliptically polarized, time delayed attosecond pulses is investigated to display a momentum distribution having the helical vortex or ring structures. The results are obtained by the strong field approximation method and… read more here.
