What Does GEKT Stand For?

GEKT stands for Generalized Extended Koopmans Theorem

The Generalized Extended Koopmans Theorem (GEKT) is a theoretical framework in quantum chemistry that extends the traditional Koopmans' theorem. It provides a method for predicting electronic excitation energies and ionization potentials in complex molecular systems. By incorporating additional interactions and many-body effects, GEKT enhances the accuracy of electronic structure calculations, facilitating a better understanding of chemical reactivity and properties in various materials. This approach is particularly valuable for investigating systems where traditional methods may be inadequate.
