Dispersive Excitations in the One-Dimensional Ionic Hubbard Model

Autor: Torbati, M. Hafez, Drescher, Nils A., Uhrig, Götz S.

Publikováno v: Phys. Rev. B 89, 245126 (2014)

A detailed study of the one-dimensional ionic Hubbard model with interaction $U$ is presented. We focus on the band insulating (BI) phase and the spontaneously dimerized insulating (SDI) phase which appears on increasing $U$. By a recently introduced
