Descriptions of Electrons beyond Density Functional Theory

The properties and behavior of molecules and materials are governed by their underlying distribution of electrons. Much of the chemistry and physics communities have adopted density functional theory (DFT) as THE means to approximate Schroedinger's wave equation for electrons. But current implementations of DFT have domains where DFT fails not only quantitatively but even qualitatively to deliver the correct physics. This talk will discuss some of those cases and what we have done to move beyond DFT to properly account for the quantum nature of electrons (namely to account for their indistinguishability, via exchange, and their correlated motion).
