Quantum critical behavior of the one-dimensional ionic Hubbard model
S. R. Manmana, V. Meden, R. M. Noack +1
We study the zero-temperature phase diagram of the half-filled one-dimensional ionic Hubbard model. This model is governed by the interplay of the on-site Coulomb repulsion and an…

Analytical and Numerical Treatment of the Mott--Hubbard Insulator in Infinite Dimensions
Michael P. Eastwood, Florian Gebhard, Eva Kalinowski +2
We calculate the density of states in the half-filled Hubbard model on a Bethe lattice with infinite connectivity. Based on our analytical results to second order in , we prop…
