Exact density functional theory with the density matrix renormalization group
Year: 2011
Type: preprint
Abstract: Combining density functional theory with controlled numerical methods for strongly correlated systems could greatly extend the range of both. We use the density matrix renormalization group method to perform Kohn-Sham calculations with the exact density functional for a set of electronic structure models in one dimension. When correlations are strong, the total electronic density converges quickly, but the spin densities do not.
