Density-functional treatment of model Hamiltonians: basic concepts and application to the Heisenberg model
Valter L. Libero, Klaus Capelle
We describe how density-functional theory, well-known for its many uses in ab initio calculations of electronic structure, can be used to study the ground state of inhomogeneous mo…
A bird's-eye view of density-functional theory
Klaus Capelle
This paper is the outgrowth of lectures the author gave at the Physics Institute and the Chemistry Institute of the University of Sao Paulo at Sao Carlos, Brazil, and at the VIII't…
Density-functional theory for the Hubbard model: numerical results for the Luttinger liquid and the Mott insulator
K. Capelle, N. A. Lima, M. F. Silva +1
We construct and apply an exchange-correlation functional for the one-dimensional Hubbard model. This functional has built into it the Luttinger-liquid and Mott-insulator correlati…
Relativistic Theory of Superconductivity
K. Capelle, M. A. L. Marques, E. K. U. Gross
The relativistic generalization of the theory of superconductivity is reviewed with respect to its conceptual basis and first applications. The construction of relativistically cov…
