Population Control Bias and Importance Sampling in Full Configuration Interaction Quantum Monte Carlo
Khaldoon Ghanem, Niklas Liebermann, Ali Alavi
Population control is an essential component of any projector Monte Carlo algorithm. This control mechanism usually introduces a bias in the sampled quantities that is inversely pr…
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…
Exceptional points in the elliptical three-disk scatterer using semiclassical periodic orbit quantization
Niklas Liebermann, Jörg Main, Günter Wunner
The three-disk scatterer has served as a paradigm for semiclassical periodic orbit quantization of classical chaotic systems using Gutzwiller's trace formula. It represents an open…
