Ultrafast laser-driven quantum dynamics in positronium chloride
Einar Aurbakken, Håkon Emil Kristiansen, Simen Kvaal +2
We present a computational study of the laser-driven quantum dynamics of positronium (Ps), PsH, and PsCl at the time-dependent Hartree-Fock level of theory. To eliminate finite-bas…
Magnetic Optical Rotation from Real-Time Simulations in Finite Magnetic Fields
Benedicte Sverdrup Ofstad, Meilani Wibowo-Teale, Håkon Emil Kristiansen +8
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-f…
Transient spectroscopy from time-dependent electronic-structure theory without multipole expansions
Einar Aurbakken, Benedicte Sverdrup Ofstad, Håkon Emil Kristiansen +5
Based on the work done by an electromagnetic field on an atomic or molecular electronic system, a general gauge invariant formulation of transient absorption spectroscopy is presen…
