From Gapped Excitons to Gapless Triplons in One Dimension
Mohsen Hafez Torbati, Nils A. Drescher, Götz S. Uhrig
Often, exotic phases appear in the phase diagrams between conventional phases. Their elementary excitations are of particular interest. Here, we consider the example of the ionic H…

Dispersive Excitations in the One-Dimensional Ionic Hubbard Model
M. Hafez Torbati, Nils A. Drescher, Götz S. Uhrig
A detailed study of the one-dimensional ionic Hubbard model with interaction is presented. We focus on the band insulating (BI) phase and the spontaneously dimerized insulating…
