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…
A Projector Quantum Monte Carlo Method for non-linear wavefunctions
Lauretta R. Schwarz, A. Alavi, George H. Booth
We reformulate the projected imaginary-time evolution of Full Configuration Interaction Quantum Monte Carlo in terms of a Lagrangian minimization. This naturally leads to the admis…
Emergence of Critical Phenomena in Full Configuration Interaction Quantum Monte Carlo
James J. Shepherd, Lauretta R. Schwarz, Robert E. Thomas +3
There has been recent literature discussion on the origin and severity of the `sign problem' in full configuration interaction quantum Monte Carlo (FCIQMC) and its `initiator' adap…
