Abstract

The project is intended for the construction of simplified models of molecules and many-electron atoms through identical particles in Fock space formalism. The study of the double harmonic oscillator will be critical for modeling a simple diatomic molecule. The simplified models will facilitate the understanding of the many-body effects that take place in molecules and many-electron atoms.(AU)
