Dimensional-scaling estimate of the energy of a large system from that of its building blocks: Hubbard model and Fermi liquid
K. Capelle, L. N. Oliveira
A simple, physically motivated, scaling hypothesis, which becomes exact in important limits, yields estimates for the ground-state energy of large, composed, systems in terms of th…

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…

A new non-Fermi liquid fixed point
Tae-Suk Kim, L. N. Oliveira, D. L. Cox
We study a new exchange interaction in which the conduction electrons with pseudo spin interact with the impurity spin . Due to the overscreening of the impurity…
