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 ...

    We study the effects of magnetic fields in the context of magnetic field density-functional theory (BDFT), where the energy is a functional of the electron density ρ and the magnetic field B. We show that this approach is ...

    The Berry connection and curvature are key components of electronic structure calculations for atoms and molecules in magnetic fields. They ensure the correct translational behavior of the effective nuclear Hamiltonian and ...
  • Wirz, Lukas Nico; Dimitrova, Maria; Fliegl, Heike; Sundholm, Dage (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    The topology of twisted molecular rings is characterized by the linking number, which is equal to the sum of the twist—a local property of the molecular frame—and the writhe—a global parameter, which represents the bending ...
