Model atomic systems in intense laser fields: exact time-dependent density functional and Floquet theory Kapoor, Varun , 1983- Text theses Text Hochschulschrift 2013 2013 eng electronic resourceremoteComputermedienOnline-Ressourcetext/htmlapplication/pdfOnline-Ressource Ill., graph. Darst. The ab initio solution of the time-dependent Schrödinger equation for a many-body system is feasible for only a few constituents. Success of TDDFT when it comes to highly correlated electron dynamics is very limited. In this thesis, the exact exchange-correlation potential for the highly correlated process of autoionization is constructed. One may try to employ the time-periodicity of external drivers. If this could also be applied to the time-dependent Kohn-Sham equation the time-dependent many-body problem could be reduced to a time-independent one. It is investigated if this is possible. vorgelegt von Varun Kapoor Rostock, Univ., Mathematisch-Naturwiss.
