First application of the transcorrelated method to noncovalent interactions: The A24 dataset
Johannes Hauskrecht, Stephanie Lambie, Evelin Martine Corvid Christlmaier +3
We present the first application of transcorrelated (TC) coupled-cluster (CC) theory to noncovalent interactions within the xTC approximation. The method is assessed for the A24 da…
ElemCo.jl: A Julia package for electron-correlation methods
Daniel Kats, Charlotte Rickert, Thomas Schraivogel +3
We present ElemCo.jl, an open-source Julia package for molecular electronic structure and properties calculations with a particular emphasis on Coupled Cluster and Distinguishable…
Orbital-Optimized Quasi-Variational Distinguishable Cluster Doubles Method
Fangcheng Wu, Daniel Kats
We present the orbital-optimized quasi-variational distinguishable cluster doubles (OQVDCD) method, obtained by applying the distinguishable cluster (DC) approximation to orbital-o…
Compression of virtual spaces in transcorrelated methods via singular value decomposition: application to the G2 set
Yifan Cheng, Kristoffer Simula, Johannes Hauskrecht +3
We introduce a new singular-value-decomposition-based scheme for constructing small virtual spaces out of large basis sets for transcorrelated (TC) calculations, termed SVD-TC. Thi…
An Additive Reference Correction Scheme for the Transcorrelated Method
Johannes Hauskrecht, Kristoffer Simula, Yifan Cheng +3
We introduce an additive reference correction for the transcorrelated (TC) method and its three-body mean-field approximation (xTC), to improve energy differences computed in small…
Application of the aperiodic defect model to a negatively charged monovacancy in phosphorene
Charlotte Rickert, Lily Barta, Ernst-Christian Flach +2
We apply the recently introduced aperiodic defect model (ADM) to a negatively charged monovacancy in a phosphorene monolayer. In contrast to conventional supercell approaches, the…
