AutoHF: a general Hartree-Fock solver utilizing direct energy minimization with automatic differentiation

Ryan Levy, Brandon Eskridge, Lukas Weber +2

We present autohf, a general, easy-to-use mean-field solver for quantum many-fermion Hamiltonians. It allows the user to bypass the process of deciphering the mean-field form for e…

Downfolding from Ab Initio to Interacting Model Hamiltonians: Comprehensive Analysis and Benchmarking of the DFT+cRPA Approach

Yueqing Chang, Erik G. C. P. van Loon, Brandon Eskridge +8

Model Hamiltonians are regularly derived from first-principles data to describe correlated matter. However, the standard methods for this contain a number of largely unexplored app…

Ab initio Calculations in Atoms, Molecules, and Solids, Treating Spin-Orbit Coupling and Electron Interaction on Equal Footing

Brandon Eskridge, Henry Krakauer, Hao Shi +1

We incorporate explicit, non-perturbative treatment of spin-orbit coupling into ab initio auxiliary-field quantum Monte Carlo (AFQMC) calculations. The approach allows a general co…

Local embedding and effective downfolding in the auxiliary-field quantum Monte Carlo method

Brandon Eskridge, Henry Krakauer, Shiwei Zhang

A local embedding and effective downfolding scheme has been developed and implemented in the auxiliary-field quantum Monte Carlo (AFQMC) method. A local cluster in which electrons…
