arXiv:2605.06215v2 Announce Type: replace-cross Abstract: Multiconfiguration pair-density functional theory (MC-PDFT) provides an efficient and accurate framework for computing electronic energies in strongly correlated molecular systems, with the quality of the on-top functional being a key determinant of its predictive accuracy. Here, we introduce MMCDDB26, a rigorously curated benchmark database comprising 76 datasets and 1,495 reactions. We further propose a constrained, large-language-model-assisted optimization workflow for the development and assessment of MC-PDFT functionals. Using thi
The development of sophisticated computational chemistry methods, including those assisted by large language models, is a direct consequence of advancements in AI and increased computational power allowing for more complex simulations.
This development can significantly accelerate the discovery and design of new materials, drugs, and chemicals by improving the accuracy and efficiency of quantum chemistry calculations for complex molecular systems.
The accuracy and speed of multiconfiguration pair-density functional theory (MC-PDFT) calculations for strongly correlated molecular systems are potentially enhanced, leading to more reliable predictions in chemical research.
