Spin-pure Stochastic-CASSCF via GUGA-FCIQMC applied to Iron Sulfur Clusters

Autor: Dobrautz, Werner, Weser, Oskar, Bogdanov, Nikolay, Alavi, Ali, Manni, Giovanni Li

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, which is based on the graphical unitary group approach (GUGA). This

Autor: Guther, Kai, Anderson, Robert J., Blunt, Nick S., Bogdanov, Nikolay A., Cleland, Deidre, Dattani, Nike, Dobrautz, Werner, Ghanem, Khaldoon, Jeszenski, Peter, Liebermann, Niklas, Manni, Giovanni Li, Lozovoi, Alexander Y., Luo, Hongjun, Ma, Dongxia, Merz, Florian, Overy, Catherine, Rampp, Markus, Samanta, Pradipta K., Schwarz, Lauretta R., Shepherd, James J., Smart, Simon D., Vitale, Eugenio, Weser, Oskar, Booth, George H., Alavi, Ali

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 Hamiltonian matrix on a sparse sampling of the wave function. The program utiliz
