Efficient calculation of dispersion energy for multireference systems with Cholesky decomposition. Application to excited-state interactions
Michał Hapka, Agnieszka Krzemińska, Marcin Modrzejewski +2
We propose an algorithm, that scales with the fifth power of the system size, for computing the second-order dispersion energy for monomers described with multiconfigurational wave…

F-12 density matrices and cumulants from the explicitly connected coupled-cluster theory
Aleksandra M. Tucholska, Marcin Modrzejewski, Robert Moszynski
We present the expansion to the expectation value coupled cluster theory (XCC) to the wavefunctions that include the inter electronic distances explicitly. We have extende…
