Local density with gap functional by Jana et al
In J. Chem. Phys. 159, 114109 (2023) Jana et al apparently describe a new LDA correlation functional. It appears they have done self-consistent calculations with the functional
We implement in the Q-Chem program [116] the LDAg functional, and we perform self-consistent calculations, with the def2-QZVP basis set, for the G21IP test121 of the ionization potential of atoms and molecules, which is widely used in the assessment of density functionals for this property.[121]
