Combined unitary and symmetric group approach applied to low-dimensional spin systems
Werner Dobrautz, Vamshi M. Katukuri, Nikolay A. Bogdanov +3
A novel combined unitary and symmetric group approach is used to study the spin- Heisenberg model and related Fermionic systems in a spin-adapted representation, using…
Transcorrelated coupled cluster methods
Thomas Schraivogel, Aron J. Cohen, Ali Alavi +1
Transcorrelated coupled cluster and distinguishable cluster methods are presented. The Hamiltonian is similarity transformed with a Jastrow factor in the first quantisation, which…
Towards efficient and accurate \emph{ab initio} solutions to periodic systems via transcorrelation and coupled cluster theory
Ke Liao, Thomas Schraivogel, Hongjun Luo +2
We propose a streamlined combination scheme of the transcorrelation (TC) and coupled cluster (CC) theory, which not only increases the convergence rate with respect to the basis se…
