Journal ArticleDOI
Generalized Gradient Approximation Made Simple
TL;DR: A simple derivation of a simple GGA is presented, in which all parameters (other than those in LSD) are fundamental constants, and only general features of the detailed construction underlying the Perdew-Wang 1991 (PW91) GGA are invoked.
Journal ArticleDOI
Accurate and simple analytic representation of the electron-gas correlation energy
John P. Perdew,Yue Wang +1 more
TL;DR: A simple analytic representation of the correlation energy for a uniform electron gas, as a function of density parameter and relative spin polarization \ensuremath{\zeta}, which confirms the practical accuracy of the VWN and PZ representations and eliminates some minor problems.
Journal ArticleDOI
Atoms, molecules, solids, and surfaces: Applications of the generalized gradient approximation for exchange and correlation.
John P. Perdew,J. A. Chevary,S. H. Vosko,Koblar A. Jackson,Mark R. Pederson,David J. Singh,Carlos Fiolhais +6 more
TL;DR: A way is found to visualize and understand the nonlocality of exchange and correlation, its origins, and its physical effects as well as significant interconfigurational and interterm errors remain.
Journal ArticleDOI
Density-functional approximation for the correlation energy of the inhomogeneous electron gas
TL;DR: Numerical results for atoms, positive ions, and surfaces are close to the exact correlation energies, with major improvements over the original LM approximation for the ions and surfaces.
Journal ArticleDOI
Self-interaction correction to density-functional approximations for many-electron systems
John P. Perdew,Alex Zunger +1 more
TL;DR: In this paper, the self-interaction correction (SIC) of any density functional for the ground-state energy is discussed. But the exact density functional is strictly selfinteraction-free (i.e., orbitals demonstrably do not selfinteract), but many approximations to it, including the local spin-density (LSD) approximation for exchange and correlation, are not.
