    • Absorbers as detectors for unbound quantum systems 

      Selstø, Sølve (Physical Review A (PRA);Vol. 106, Iss. 4, Peer reviewed; Journal article, 2022-10-19)
      Complex absorbing potentials are frequently employed in quantum calculations. One of the advantages that such absorbers provide is the ability to attenuate outgoing waves in simulations of unbound systems, thus allowing ...

    • 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 ...

    • Schrödinger formulation of the nondipole light-matter interaction consistent with relativity 

      Førre, Morten; Selstø, Sølve (Physical Review A (PRA);Vol. 101, Iss. 6 — June 2020, Journal article; Peer reviewed, 2020-06-25)
      An alternative and powerful Schrödinger-like equation for describing beyond dipole laser-matter interactions and leading relativistic corrections is derived. It is shown that this particular formulation is numerically very ...
