Ab Initio Approach for Quantum Magnets with Coupled Cluster and Transcorrelation
Kristoffer Simula, Nikolay A. Bogdanov, Olle Gunnarsson +2
The nearest-neighbour exchange coupling is the simplest ingredient of model Hamiltonians used to understand magnetism in real materials. Nevertheless, its ab initio determina…
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…
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…
