Survey of eigenproblem treatment in quantum chemistry and density functional theory

Muller, Richard P.

{sm_bullet}HF/DFT are one-particle approximation to the Schrodinger equation {sm_bullet} The one-particle, mean field approaches are what lead to the nonlinear eigenvalue problem {sm_bullet} DFT includes a parameterized XC functional that reproduces many-electron effects -Very accurate ground state structures and energies - Problematic for excited states, band gaps
