What Does GGA Stand For?

GGA stands for Generalized Gradient Approxn

GGA, or Generalized Gradient Approximation, is a computational method used in quantum chemistry and condensed matter physics to improve the accuracy of density functional theory (DFT) calculations. It enhances the treatment of exchange-correlation effects by incorporating gradient information of the electron density, providing a more reliable framework for predicting molecular and material properties. GGA is widely utilized in various applications, including materials science, nanotechnology, and chemical research, due to its balance between computational efficiency and accuracy.
