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…

Density-functionals not based on the electron gas: Local-density approximation for a Luttinger liquid
N. A. Lima, M. F. Silva, L. N. Oliveira +1
By shifting the reference system for the local-density approximation (LDA) from the electron gas to other model systems one obtains a new class of density functionals, which by des…
