28 Jun 2005 | | Subject: | Superconductivity; Strongly Correlated Electrons | cond-mat.supr-con cond-mat.str-el | | Abstract: | Combining the Hohenberg-Kohn theorem with the Gutzwiller projection, we develop a density functional theory of strongly correlated electron systems. The optimization of the energy functional leads to a thoroughly unrestricted self-consistent re-normalized mean field theory. Applying the theory to high-$T_c$ superconductors, we discuss the issues of electronic inhomogeneity, the superfluid density, and in particular the local electron density of states. The results account for many intriguing aspects of the phenomenology. | | Source: | arXiv, cond-mat/0506712 | | Services: | Forum | Review | PDF | Favorites | |
