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…
Spin-pure Stochastic-CASSCF via GUGA-FCIQMC applied to Iron Sulfur Clusters
Werner Dobrautz, Oskar Weser, Nikolay Bogdanov +2
In this work we demonstrate how to compute the one- and two-body reduced density matrices within the spin-adapted full configuration interaction quantum Monte Carlo (FCIQMC) method…
Benchmark study of Nagaoka ferromagnetism by spin-adapted full configuration interaction quantum Monte Carlo
Sujun Yun, Werner Dobrautz, Hongjun Luo +1
We investigate Nagaoka ferromagnetism in the two-dimensional Hubbard model with one hole using the spin-adapted ( conserving) full configuration interaction quantum Monte Ca…
