Hayashi Pseudopotential

The Hayashi Pseudopotential is a mathematical model used in quantum physics to simplify calculations involving electrons in atoms, especially in complex systems like solids. Instead of analyzing the complicated interactions between an electron and all the atomic nuclei directly, the pseudopotential replaces the core electrons and nucleus with an effective "average" potential. This allows scientists to focus on the behavior of valence electrons (the ones involved in chemical bonding) more efficiently, making it easier to study material properties, electronic structures, and related phenomena without losing essential accuracy.
