Towards Large-Scale AFQMC Calculations: Large Time Step Auxiliary-Field Quantum Monte Carlo
Zoran Sukurma, Martin Schlipf, Moritz Humer +2
We report modifications of the ph-AFQMC algorithm that allow the use of large time steps and reliable time step extrapolation. Our modified algorithm eliminates size-consistency er…

Benchmark Phaseless Auxiliary-Field Quantum Monte Carlo Method for Small Molecules
Z. Sukurma, M. Schlipf, M. Humer +2
We report a scalable Fortran implementation of the phaseless auxiliary-field quantum Monte Carlo (ph-AFQMC) and demonstrate its excellent performance and beneficial scaling with re…
