Evaluating Multiconfigurational Trials for Accurate Phaseless Auxiliary-Field Quantum Monte Carlo on 3d Transition Metal Complexes
Hung T. Vuong, Ankit Mahajan, John L. Weber +3
In this study, we evaluate multi-configurational trial wave function protocols for phaseless auxiliary field quantum Monte Carlo (ph-AFQMC) on transition metal containing systems.…
Efficient Long-Range Machine Learning Force Fields for Liquid and Materials Properties
John L. Weber, Rishabh D. Guha, Garvit Agarwal +10
Machine learning force fields (MLFFs) have emerged as a sophisticated tool for cost-efficient atomistic simulations approaching DFT accuracy, with recent message passing MLFFs able…
Scalable Ab Initio Electronic Structure Methods with Near Chemical Accuracy for Main Group Chemistry
Yujing Wei, Sibali Debnath, John L. Weber +3
This study evaluates the precision of widely recognized quantum chemical methodologies, CCSD(T), DLPNO-CCSD(T) and localized ph-AFQMC, for determining the thermochemistry of main g…
The Design of New Practical Constraints in Auxiliary-Field Quantum Monte Carlo
John L. Weber, Hung Vuong, Richard A. Friesner +1
We formulate and characterize a new constraint for Auxiliary Field Quantum Monte Carlo (AFQMC) applicable for general fermionic systems, which allows for the accumulation of phase…
A Localized-Orbital Energy Evaluation for Auxiliary-Field Quantum Monte Carlo
John L. Weber, Hung Vuong, Pierre A. Devlaminck +4
Phaseless Auxiliary-Field Quantum Monte Carlo (ph-AFQMC) has recently emerged as a promising method for the production of benchmark-level simulations of medium to large-sized molec…
Predicting Ligand-Dissociation Energies of 3d Coordination Complexes with Auxiliary-Field Quantum Monte Carlo
Benjamin Rudshteyn, Dilek Coskun, John L. Weber +5
Transition metal complexes are ubiquitous in biology and chemical catalysis, yet they remain difficult to accurately describe with ab initio methods due to the presence of a large…
