Ruiheng and Xiliang’s paper “Unphysical Solutions in Coupled-Cluster-Based Random Phase Approximation and How to Avoid Them” is posted to arXiv. CC-based RPA holds great promise for studying transition metal surface chemistry, and this work substantially extends its applicability by improving numerical stability in low-gap systems.

We develop and apply quantum chemistry-based computational tools to study functional molecules and materials relevant to energy, storage, and pharmaceutical applications. We are particularly interested in developing and extending theories and algorithms that exploit locality, sparsity, and low-rank structures in correlated wavefunctions to enable accurate and scalable electronic structure calculations. This research thrust naturally intersects with emerging symmetry-aware machine learning techniques such as equivariant neural networks for tensorial learning, and also informs the development of more approximate methods such as density functional theory and semi-empirical methods. We apply our newly developed tools to tackle cutting-edge problems in chemistry and materials science. Current areas of interest include molecular solids, catalyzing surfaces, and porous materials such as covalent organic frameworks.
