A computational physicist who, with D. M. Ceperley, calculated electron-gas correlation energies using Quantum Monte Carlo in 1980. Their stochastic treatment of the Schrödinger equation compared competing fluid and crystalline states. Such calculations provide benchmarks for approximate treatments of interacting electrons, where exchange and correlation make an independent-particle description insufficient.[ref]
