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…
NECI: N-Electron Configuration Interaction with emphasis on state-of-the-art stochastic methods
Kai Guther, Robert J. Anderson, Nick S. Blunt +22
We present NECI, a state-of-the-art implementation of the Full Configuration Interaction Quantum Monte Carlo algorithm, a method based on a stochastic application of the Hamiltonia…
New superexchange paths due to breathing-enhanced hopping in corner-sharing cuprates
Nikolay A. Bogdanov, Giovanni Li Manni, Sandeep Sharma +2
We present ab initio calculations of the superexchange antiferromagnetic spin coupling for two cuprates, SrCuO and LaCuO. Good agreement with experimental estim…
