Towards a systematically improvable many-body description of antiferromagnetic iron oxide
Joshua P Townsend, Raymond C Clay, Thomas R Mattsson +5
We report variational and fixed-node diffusion quantum Monte Carlo (QMC) calculations of anti-ferromagnetic iron oxide (FeO) in the ground state B1 crystal structure. The goal of t…
An efficient hybrid orbital representation for quantum Monte Carlo calculations
Ye Luo, Kenneth P. Esler, Paul R. C. Kent +1
The scale and complexity of quantum system to which real-space quantum Monte Carlo (QMC) can be applied in part depends on the representation and memory usage of the trial wavefunc…
QMCPACK : An open source ab initio Quantum Monte Carlo package for the electronic structure of atoms, molecules, and solids
Jeongnim Kim, Andrew Baczewski, Todd D. Beaudet +45
QMCPACK is an open source quantum Monte Carlo package for ab-initio electronic structure calculations. It supports calculations of metallic and insulating solids, molecules, atoms,…
Momentum Distribution and Renormalization Factor in Sodium and the Electron Gas
Simo Huotari, J. Aleksi Soininen, Tuomas Pylkkänen +9
We present experimental and theoretical results on the momentum distribution and the quasiparticle renormalization factor in sodium. From an x-ray Compton-profile measurement of th…
Fundamental high pressure calibration from all-electron quantum Monte Carlo calculations
K. P. Esler, R. E. Cohen, B. Militzer +3
We develop an all-electron quantum Monte Carlo (QMC) method for solids that does not rely on pseudopotentials, and use it to construct a primary ultra-high pressure calibration bas…
Backflow Correlations for the Electron Gas and Metallic Hydrogen
M. Holzmann, D. M. Ceperley, C. Pierleoni +1
We justify and evaluate backflow-threebody wavefunctions for a two component system of electrons and protons. Based on the generalized Feynman-Kacs formula, many-body perturbation…
