Embracing a new era of highly efficient and productive quantum Monte Carlo simulations

Amrita Mathuriya, Ye Luo, Raymond C. Clay +3

QMCPACK has enabled cutting-edge materials research on supercomputers for over a decade. It scales nearly ideally but has low single-node efficiency due to the physics-based abstra…

Optimization and parallelization of B-spline based orbital evaluations in QMC on multi/many-core shared memory processors

Amrita Mathuriya, Ye Luo, Anouar Benali +2

B-spline based orbital representations are widely used in Quantum Monte Carlo (QMC) simulations of solids, historically taking as much as 50% of the total run time. Random accesses…

Energy density matrix formalism for interacting quantum systems: a quantum Monte Carlo study

Jaron T. Krogel, Jeongnim Kim, Fernando A. Reboredo

We develop an energy density matrix that parallels the one-body reduced density matrix (1RDM) for many-body quantum systems. Just as the density matrix gives access to the number d…

Equations of state and stability of MgSiO perovskite and post-perovskite phases from quantum Monte Carlo simulations

Yangzheng Lin, R. E. Cohen, Stephen Stackhouse +4

We have performed quantum Monte Carlo (QMC) simulations and density functional theory (DFT) calculations to study the equations of state of MgSiO perovskite (Pv) and post-perov…
