What Does CCGF Stand For?

CCGF stands for Coupled Cluster Green Function

CCGF, or Coupled Cluster Green Function, is a sophisticated mathematical framework used in quantum chemistry and many-body physics to describe the electronic properties of multi-electron systems. It combines the coupled cluster method, which efficiently accounts for electron correlation, with Green function techniques to provide insight into excitation spectra and response functions. This approach is particularly valuable for studying strongly correlated systems, enabling more accurate predictions of physical phenomena such as spectral features, reaction dynamics, and phase transitions.
