GGA-Level Subsystem DFT Achieves Sub-kcal/mol Accuracy Intermolecular Interactions by Mimicking Nonlocal Functionals
Xuecheng Shao, Wenhui Mi, Michele Pavanello
The key feature of nonlocal kinetic energy functionals is their ability to reduce to the Thomas-Fermi functional in the regions of high density and to the von Weizsäcker functional…

eQE 2.0: Subsystem DFT Beyond GGA Functionals
Wenhui Mi, Xuecheng Shao, Alessandro Genova +2
By adopting a divide-and-conquer strategy, subsystem-DFT (sDFT) can dramatically reduce the computational cost of large-scale electronic structure calculations. The key ingredients…
