Minimal charge gap in the ionic Hubbard model
K. Pozgajcic, C. Gros
We study the ionic Hubbard model at temperature T=0 within the mean-field approximation, and show that the charge gap does not close completely at the ionic-band insulator to antif…

Modeling the electronic behavior of -LiV2O5: a microscopic study
R. Valenti, T. Saha-Dasgupta, J. V. Alvarez +2
We determine the electronic structure of the one-dimensional spin-1/2 Heisenberg compound -LiVO, which has two inequivalent vanadium ions, V(1) and V(2), via density-fun…
