  • A DZ white dwarf with a 30 MG magnetic field 
    Hollands, M.A.; Stopkowicz, Stella; Kitsaras, M.-P.; Hampe, F.; Blaschke, S.; Hermes, J.J. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    ABSTRACT Magnetic white dwarfs with field strengths below 10 MG are easy to recognize since the Zeeman splitting of spectral lines appears proportional to the magnetic field strength. For fields ≳100 MG, however, transition ...
  • Another Torture Track for Quantum Chemistry: Reinvestigation of the Benzaldehyde Amidation by Nitrogen-Atom Transfer from Platinum(II) and Palladium(II) Metallonitrenes 
    Verplancke, Hendrik; Diefenbach, Martin; Lienert, Jonas N.; Ugandi, Mihkel; Kitsaras, Marios-Petros; Roemelt, Michael; Stopkowicz, Stella; Holthausen, Max C. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Abstract We showcase here a dramatic failure of CCSD(T) theory that originates from the pronounced multi‐reference character of a key intermediate formed in the benzaldehyde amidation by N‐atom transfer from Pd(II) and ...
  • Magnetic optical rotation from real-time simulations in finite magnetic fields 
    Ofstad, Benedicte; Wibowo-Teale, Meilani; Kristiansen, Håkon Emil; Aurbakken, Einar; Kitsaras, Marios-Petros; Schøyen, Øyvind Sigmundson; Hauge, Eirill Strand; Irons, Tom J. P.; Kvaal, Simen; Stopkowicz, Stella; Wibowo-Teale, Andrew M.; Pedersen, Thomas Bondo (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2023)
    We present a numerical approach to magnetic optical rotation based on real-time time-dependent electronic-structure theory. Not relying on perturbation expansions in the magnetic-field strength, the formulation allows us ...
