Ab Initio Auxiliary-Field Quantum Monte Carlo in the Thermodynamic Limit

Jinghong Zhang, Meng-Fu Chen, Adam Rettig +5

Ab initio auxiliary-field quantum Monte Carlo (AFQMC) is a systematically improvable many-body method, but its application to extended solids has been severely limited by unfavorab…

Walking through Hilbert Space with Quantum Computers

Tong Jiang, Jinghong Zhang, Moritz K. A. Baumgarten +6

Computations of chemical systems' equilibrium properties and non-equilibrium dynamics have been suspected of being a "killer app" for quantum computers. This review highlights the…

Improved modularity and new features in ipie: Toward even larger AFQMC calculations on CPUs and GPUs at zero and finite temperatures

Tong Jiang, Moritz K. A. Baumgarten, Pierre-François Loos +6

ipie is a Python-based auxiliary-field quantum Monte Carlo (AFQMC) package that has undergone substantial improvements since its initial release [J. Chem. Theory Comput., 2023, 19(…

Unbiasing Fermionic Auxiliary-Field Quantum Monte Carlo with Matrix Product State Trial Wavefunctions

Tong Jiang, Bryan O'Gorman, Ankit Mahajan +1

In this work, we report, for the first time, an implementation of fermionic auxiliary-field quantum Monte Carlo (AFQMC) using matrix product state (MPS) trial wavefunctions, dubbed…

Unified definition of exciton coherence length for exciton-phonon coupled molecular aggregates

Tong Jiang, Jiajun Ren, Zhigang Shuai

Exciton coherence length (ECL) is an essential concept to characterize the nature of exciton in molecular aggregates for photosynthesis, organic photovoltaics, and light-emitting d…

A General Automatic Method for Optimal Construction of Matrix Product Operators Using Bipartite Graph Theory

Jiajun Ren, Weitang Li, Tong Jiang +1

Constructing matrix product operators (MPO) is at the core of the modern density matrix renormalization group (DMRG) and its time dependent formulation. For DMRG to be conveniently…
