Abstract:Hartree-Fock theory is widely recognized as an effective mean-field approximation for electronic structure. However, achieving higher accuracy necessitates methods that go beyond the Hartree-Fock framework. In this talk, we review selected mathematical studies of electronic structure beyond Hartree-Fock theory. Specifically, we examine the structure of wavefunctions in the Born-Oppenheimer approximation and the Müller density matrix functional, focusing on the regularity, exponential decay, and asymptotic behavior of the corresponding density matrix. It is possible to extend the study to Hartree-Fock-Bogoliubov theory.
