Antiferromagnetic Chern insulator in centrosymmetric systems
Morad Ebrahimkhas, Götz S. Uhrig, Walter Hofstetter +1
An antiferromagnetic Chern insulator (AFCI) can exist if the effect of the time-reversal transformation on the electronic state cannot be compensated by a space group operation. Th…
Simplified approach to the magnetic blue shift of Mott gaps
Mohsen Hafez-Torbati, Frithjof B. Anders, Götz S. Uhrig
The antiferromagnetic ordering in Mott insulators upon lowering the temperature is accompanied by a transfer of the single-particle spectral weight to lower energies and a shift of…
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…
