    • Solution of the Dirac equation for hydrogenlike systems exposed to intense electromagnetic pulses 

      Selstø, Sølve; Bengtsson, Jakob; Lindroth, Eva (Journal article; Peer reviewed, 2009)
      The time-dependent Dirac equation is solved numerically and compared to the corresponding prediction of the nonrelativistic Schrödinger equation for hydrogenlike systems exposed to intense laser pulses. It is found that ...

    • Solution of the time-dependent Schrödinger equation using uniform complex scaling 

      Bengtsson, Jakob; Lindroth, Eva; Selstø, Sølve (Journal article; Journal article; Peer reviewed, 2008)
      The formalism of complex rotation of the radial coordinate is studied in the context of time-dependent systems. The applicability of this method is discussed and illustrated with numerical examples involving atoms exposed ...

    • The structure behind it all 

      Lindroth, Eva; Argenti, Luca; Bengtsson, Jakob; Ferro, Fabrizio; Genkin, Michael; Selstø, Sølve (Journal article; Peer reviewed; Journal article, 2009)
      The talk discussed collisions where the structure of the systems involved plays a decisive role for the outcome of the event. For many types of charge changing processes the presence of resonant states can change the ...

    • Wave functions associated with time-dependent, complex-scaled Hamiltonians evaluated on a complex time grid 

      Bengtsson, Jakob; Lindroth, Eva; Selstø, Sølve (Journal article; Peer reviewed, 2012-01-30)
      We solve the time-dependent Schrödinger equation with themethod of uniform complex scaling and investigate the possibility to evaluate the solution on a complex time grid. With this approach it is possible to calculate ...
