Workhorse Semilocal Density Functional for Condensed Matter Physics and Quantum Chemistry
John P. Perdew, Adrienn Ruzsinszky, Gabor I. Csonka +2
Semilocal density functionals for the exchange-correlation energy are needed for large electronic systems. The Tao-Perdew-Staroverov-Scuseria (TPSS) meta-generalized gradient appro…

Restoring the density-gradient expansion for exchange in solids and surfaces
John P. Perdew, Adrienn Ruzsinszky, Gabor I. Csonka +5
Successful modern generalized gradient approximations (GGA's) are biased toward atomic energies. Restoration of the first-principles gradient expansion for exchange over a wide ran…
