Transcorrelated Theory with Pseudopotentials
Kristoffer Simula, Evelin Martine Corvid Christlmaier, Maria-Andreea Filip +4
The transcorrelated (TC) method performs a similarity transformation on the electronic Schrödinger equation via Jastrow factorization of the wave function. This has demonstrated si…
On the applicability of CCSD(T) for dispersion interactions in large conjugated systems
S. Lambie, D. Kats, D. Usyvat +1
In light of the recent discrepancies reported between fixed node diffusion Monte Carlo and local natural orbital coupled cluster with single, double and perturbative triples (CCSD(…
Transcorrelated Methods Applied to Second Row Elements
Maria-Andreea Filip, Pablo López Ríos, J. Philip Haupt +3
We explore the applicability of the transcorrelated method to the elements in the second row of the periodic table. We use transcorrelated Hamiltonians in conjunction with full con…
Tensor Decomposed Distinguishable Cluster. I. Triples Decomposition
Charlotte Rickert, Denis Usvyat, Daniel Kats
We present a cost-reduced approach for the distinguishable cluster approximation to coupled cluster with singles, doubles and iterative triples (DC-CCSDT) based on a tensor decompo…
Aperiodic defects in periodic solids
Robert H. Lavroff, Daniel Kats, Lorenzo Maschio +4
To date, computational methods for modeling defects (vacancies, adsorbates, etc.) rely on periodic supercells in which the defect is far enough from its repeated image such that th…
Orbital optimisation in xTC transcorrelated methods
Daniel Kats, Evelin M. C. Christlmaier, Thomas Schraivogel +1
We present a combination of the bi-orthogonal orbital optimisation framework with the recently introduced xTC version of transcorrelation. This allows us to implement non-iterative…
Two Determinant Distinguishable Cluster
Thomas Schraivogel, Daniel Kats
A two reference determinant version of the distinguishable cluster with singles and doubles (DCSD) has been developed. We have implemented the two determinant distinguishable clust…
