What Does APDG Stand For?

APDG stands for Antisymmetrized Product Of Delocalized Geminals Wave Function

APDG, or Antisymmetrized Product of Delocalized Geminals Wave Function, is a theoretical framework used in quantum chemistry to describe many-body systems. This approach combines the principles of antisymmetrization, essential for addressing fermionic systems, with the delocalized geminal wave functions that capture electron correlations more effectively. By employing APDG, researchers can achieve a more accurate representation of complex electronic structures and interactions, facilitating improved predictions of molecular properties and behaviors.
