    • Relativistic effects in photoionizing a circular Rydberg state in the optical regime 

      Kjellsson Lindblom, Tor Hugo Iwao; Lindroth, Eva; Førre, Morten; Selstø, Sølve (Physical Review A (PRA);102, 063108 (2020), Journal article; Peer reviewed, 2020-12-11)
      We study the photoionization process of a hydrogen atom initially prepared in a circular Rydberg state. The atom is exposed to a two-cycle laser pulse with a central wavelength of 800 nm. Before the atom approaches saturation, ...

    • Relativistic photoionization with elliptically polarized laser fields in the ultraviolet region 

      Kjellsson Lindblom, Tor Hugo Iwao; Selstø, Sølve (Physical Review A (PRA);104, 043102, Peer reviewed; Journal article, 2021-10-04)
      An alternative and powerful Schrödinger-like equation for describing beyond dipole laser-matter interactions is derived. It is shown that this particular formulation is numerically very efficient with respect to computational ...
