A reorganized Hartree-Fock framework imposes tunable orbital locality by pairing local degrees of freedom with local solution conditions, maintaining efficient SCF optimization and competitive reaction-energy accuracy.
Implements TDDFT-ris with density fitting and approximate Z-vector for fast excited-state gradients and nonadiabatic couplings in FSSH dynamics, claiming negligible errors and high efficiency for medium-sized systems.
Tuned LC-ωPBE TDDFT screening of 27 heteroatom-doped D-π-A dyes identifies boron-rich motifs as narrowing the HOMO-LUMO gap and red-shifting charge-transfer excitations for improved DSSC light harvesting.
Benchmarking of SOPPA-based methods shows HRPA(D) and SOPPA(CCSD) as most accurate overall for polarizabilities, with clear performance differences between aromatic and non-aromatic molecules and across frequency regimes.
