Chemical Interpretation of Time-Dependent Coupled-Cluster Theory
Aparna Krishnan, HÃ¥kon Emil Kristiansen, Håkon Emil Kristiansen +3
While providing a highly accurate framework for simulating laser-induced many-electron dynamics in atom and molecules, including linear and nonlinear steady-state and transient abs…

Time-dependent Gaussian basis sets for many-body systems using Rothe's method: A mean-field study
Simon Elias Schrader, HÃ¥kon Emil Kristiansen, Thomas Bondo Pedersen +1
A challenge in modeling time-dependent strong-field processes such as high-harmonic generation for many-body systems, is how to effectively represent the electronic continuum. We a…

Configuration weights in coupled-cluster theory
HÃ¥kon Emil Kristiansen, HÃ¥kon Kvernmoen, Simen Kvaal +1
We introduce a simple definition of the weight of any given Slater determinant in the coupled-cluster state, namely as the expectation value of the projection operator onto that de…
