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…

Cost-Efficient High-Resolution Linear Absorption Spectra Through Extrapolating the Dipole Moment from Real-Time Time-Dependent Electronic-Structure Theory

Eirill Hauge, Håkon Emil Kristiansen, Lukas Konecny +3

We present a novel function fitting method for approximating the propagation of the time-dependent electric dipole moment from real-time electronic structure calculations. Real-tim…

Adiabatic extraction of nonlinear optical properties from real-time time-dependent electronic-structure theory

Benedicte Sverdrup Ofstad, Håkon Emil Kristiansen, Einar Aurbakken +3

Real-time simulations of laser-driven electron dynamics contain information about molecular optical properties through all orders in response theory. These properties can be extrac…

The -diagnostic -- an a posteriori error assessment for single-reference coupled-cluster methods

Fabian M. Faulstich, Håkon E. Kristiansen, Mihaly A. Csirik +3

We propose a novel a posteriori error assessment for the single-reference coupled-cluster (SRCC) method called the -diagnostic. We provide a derivation of the -diagnostic tha…
