The Integral- and Intermediate-Screened Coupled-Cluster Method
L. K. Sørensen
We present the formulation and implementation of the integral- and intermediate-screened coupled-cluster method (ISSCC). The IISCC method gives a simple and rigorous integral and i…
The Integral Screened Configuration Interaction Method
Lasse Kragh Sørensen, Sebastian Bauch, Lars Bojer Madsen
We present the formulation and implementation of the Integral-Screened Configuration-Interaction method (ISCI). The ISCI is a minimal-operational count integral-driven direct Confi…
What do we approximate and what are the consequences in perturbation theory?
Lasse Kragh Sørensen, Roland Lindh, Marcus Lundberg
We present a discussion of the consequences in perturbation theory when an exact eigenfunctions and eigenvalues to to the zeroth order Hamiltonian cannot be found. Since the…
Time-dependent generalized-active-space configuration-interaction approach to photoionization dynamics of atoms and molecules
Sebastian Bauch, Lasse Kragh Sørensen, Lars Bojer Madsen
We present a wave-function based method to solve the time-dependent many-electron Schrödinger equation (TDSE) with special emphasis on strong-field ionization phenomena. The theory…
