      Kjellsson Lindblom, Tor Hugo Iwao; Lindroth, Eva; Førre, Morten; Selstø, Sølve (Journal article; Peer reviewed, 2020)
      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, ...
