Predicting Material Properties with Quantum Monte Carlo

Written by: Nils Heinonen, Argonne Leadership Computing Facility Recent advances in quantum Monte Carlo (QMC) methods have the potential to revolutionize computational materials science, a discipline traditionally driven by density functional theory (DFT). While DFT—an approach that uses quantum-mechanical modeling to examine the electronic structure of complex systems—provides convenience to…
