What Does GQDPT Stand For?

GQDPT stands for Generalized Quasidegenerate Perturbation Theory

Generalized Quasidegenerate Perturbation Theory (GQDPT) is an advanced computational method used in quantum chemistry and physics to analyze systems with nearly degenerate states. By extending traditional perturbation techniques, GQDPT effectively addresses challenges associated with level crossings and closely spaced energy levels. This approach enhances the accuracy of predictions related to molecular properties and interactions, making it a vital tool for researchers studying complex quantum systems and their behaviors under perturbations.
