Description
Atoms and ions have been a great `playground' for (atomic) theory in order to understand the interactions in matter and especially with light from a wide range of frequencies. Apart from the ubiquitous electric-dipole interaction of optical plane-wave radiation, which determines our everyday's life and experiences, strong-field processes and vortex beams have attracted much interest during the past 20 years. Up to the present, however, rather little is known how (clouds of) atoms and molecules respond to intense fields and how the properties of the incident light affect their excitation, ionization and subsequent relaxation dynamics. I shall review and discuss from the viewpoint of computational atomic physics some recent results on the ionization and recombination of atoms and ions  in intense fields.
