A new scale anomaly in Dirac matter
Matteo Baggioli, Maxim N. Chernodub, Karl Landsteiner +2
The dynamics of Dirac semimetals is modeled at low energies by the massless Dirac Hamiltonian with the Fermi velocity replacing the velocity of light. The classical action is scale…

Topological Anderson insulating phases in the interacting Haldane model
Joao S. Silva, Eduardo V. Castro, Rubem Mondaini +2
We analyze the influence of disorder and strong correlations on the topology in two dimensional Chern insulators. A mean field calculation in the half-filled Haldane model with ext…
