Nonlocal van der Waals density functional: The simpler the better
Oleg A. Vydrov, Troy Van Voorhis
We devise a nonlocal correlation energy functional that describes the entire range of dispersion interactions in a seamless fashion using only the electron density as input. The ne…
Dispersion interactions from a local polarizability model
Oleg A. Vydrov, Troy Van Voorhis
A local approximation for dynamic polarizability leads to a nonlocal functional for the long-range dispersion interaction energy via an imaginary-frequency integral. We analyze sev…
Assessing the Performance of Recent Density Functionals for Bulk Solids
Gabor I. Csonka, John P. Perdew, Adrienn Ruzsinszky +5
We assess the performance of recent density functionals for the exchange-correlation energy of a nonmolecular solid, by applying accurate calculations with the GAUSSIAN, BAND, and…
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…
Generalized gradient approximation for solids and their surfaces
John P. Perdew, Adrienn Ruzsinszky, Gabor I. Csonka +5
Successful modern generalized gradient approximations (GGA) are biased toward atomic energies. Restoration of the first-principles gradient expansion for the exchange energy over a…
