Systematic Comparison and Cross-validation of Fixed-Node Diffusion Monte Carlo and Phaseless Auxiliary-Field Quantum Monte Carlo in Solids
Fionn D. Malone, Anouar Benali, Miguel A. Morales +3
Quantum Monte Carlo (QMC) methods are some of the most accurate methods for simulating correlated electronic systems. We investigate the compatibility, strengths and weaknesses of…
Towards a Systematic Improvement of the Fixed-Node Approximation in Diffusion Monte Carlo for Solids -- A Case Study In Diamond
Anouar Benali, Kevin Gasperich, Kenneth D. Jordan +9
While Diffusion Monte Carlo (DMC) is in principle an exact stochastic method for \textit{ab initio} electronic structure calculations, in practice the fermionic sign problem necess…
Review of the First Charged-Particle Transport Coefficient Comparison Workshop
P. E. Grabowski, S. B. Hansen, M. S. Murillo +42
We present the results of the first Charged-Particle Transport Coefficient Code Comparison Workshop, which was held in Albuquerque, NM October 4-6, 2016. In this first workshop, sc…
A new generation of effective core potentials from correlated calculations: 4s and 4p main group elements and first row additions
Guangming Wang, Abdulgani Annaberdiyev, Cody A. Melton +3
Recently, we developed a new method for generating effective core potentials (ECPs) using valence energy isospectrality with explicitly correlated all-electron (AE) excitations and…
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…
