What Does GGC Stand For?

GGC stands for Generalized Gradient Corrected Density Functional

GGC, or Generalized Gradient Corrected Density Functional, refers to a class of computational methods used in quantum chemistry and solid-state physics to approximate the exchange-correlation energy of a many-electron system. By incorporating not only electron density but also its gradient, GGC functionals provide enhanced accuracy in predicting molecular and material properties compared to traditional local density approximations. These methods are essential in density functional theory (DFT), offering improved reliability for a wide range of systems, including complex molecules and materials.
