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…
New generation of effective core potentials from correlated calculations: 3d transition metal series
Abdulgani Annaberdiyev, Guangming Wang, Cody A. Melton +3
Recently, we have introduced a new generation of effective core potentials (ECPs) designed for accurate correlated calculations but equally useful for a broad variety of approaches…
New generation of effective core potentials from correlated calculations: 2nd row elements
M. Chandler Bennett, Guangming Wang, Abdulgani Annaberdiyev +3
Very recently, we have introduced correlation consistent effective core potentials (ccECPs) derived from many-body approaches with the main target being its use in explicitly corre…
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,…
