After the derivation of the equations of motion, TDRNOT is benchmarked with the help of a numerically exactly solvable model helium atom in laser fields. It is shown that, unlike TDDFT, TDRNOT is able to describe doubly-excited states, Fano profiles in electron and absorption spectra, auto-ionization, Rabi oscillations, high harmonic generation, non-sequential ionization, and single-photon double ionization in excellent agreement with the corresponding TDSE results.<eng> vorgelegt von Mārtin̦s Brics aus Riga, Lettland Enthält 5 Beiträge aus verschiedenen Zeitschriften Kumulative Dissertation Universität Rostock 2016 530 UL 1000 33.23 http://rosdok.uni-rostock.de/resolve/urn/urn:nbn:de:gbv:28-diss2017-0008-7 Benchmarking time-dependent renormalized natural orbital theory with exact solutions for a laser-driven model helium atom--(DE-627)876558368 urn:nbn:de:gbv:28-diss2017-0008-7 oclc: 968779956 ppn: (DE-627)877014035
