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…

Exchange and Correlation in Open Systems of Fluctuating Electron Number
John P. Perdew, Adrienn Ruzsinszky, Gábor I. Csonka +4
While the exact total energy of a separated open system varies linearly as a function of average electron number between adjacent integers, the energy predicted by semi-local densi…
