  • Adiabatic extraction of nonlinear optical properties from real-time time-dependent electronic-structure theory 
    Ofstad, Benedicte Sverdrup; Kristiansen, Håkon Emil; Aurbakken, Einar; Schøyen, Øyvind Sigmundson; Kvaal, Simen; Pedersen, Thomas Bondo (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Real-time simulations of laser-driven electron dynamics contain information about molecular optical properties through all orders in response theory. These properties can be extracted by assuming convergence of the power ...
  • Linear and Nonlinear Optical Properties from TDOMP2 Theory 
    Kristiansen, Håkon Emil; Ofstad, Benedicte Sverdrup; Hauge, Eirill Strand; Aurbakken, Einar; Schøyen, Øyvind Sigmundson; Kvaal, Simen; Pedersen, Thomas Bondo (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    We present a derivation of real-time (RT) time-dependent orbital-optimized Møller–Plesset (TDOMP2) theory and its biorthogonal companion, time-dependent non-orthogonal OMP2 theory, starting from the time-dependent bivariational ...
  • Time-Dependent Coupled-Cluster Theory 
    Ofstad, Benedicte Sverdrup; Aurbakken, Einar; Schøyen, Øyvind Sigmundson; Kristiansen, Håkon Emil; Kvaal, Simen; Pedersen, Thomas Bondo (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2023)
    Recent years have witnessed an increasing interest in time-dependent coupled-cluster (TDCC) theory for simulating laser-driven electronic dynamics in atoms and molecules, and for simulating molecular vibrational dynamics. ...
  • Time-domain quantum dynamics: Optical properties from time-dependent electronic-structure theory 
    Ofstad, Benedicte Sverdrup (Doctoral thesis / Doktoravhandling, 2023)
    Within the field of nonlinear optics, nonlinear optical properties are defined as frequency-dependent responses. This definition emerged in the frequency domain, as lasers used in these early experiments emitted monochromatic ...
