Electronic properties of the dimerized one-dimensional Hubbard model using lattice density-functional theory
R. Lopez-Sandoval, G. M. Pastor
The dimerized one-dimensional Hubbard model is studied in the framework of lattice density-functional theory (LDFT). The single-particle density matrix gamma_{ij} with respect to t…

Density-Matrix functional theory of strongly-correlated lattice fermions
R. Lopez-Sandoval, G. M. Pastor
A density functional theory (DFT) of lattice fermion models is presented, which uses the single-particle density matrix gamma_{ij} as basic variable. A simple, explicit approximati…
