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…
Robust band of critical states in T broken fermionic systems with lattice selective disorder
Eduardo V. Castro, Raphael de Gail, M. Pilar López-Sancho +1
We analyze the localization properties of two dimensional systems based on partite lattices with a basis. Contrary to standard results, we find that a band of critical states emerg…
Direct measurement of a beta function and an indirect check of the Schwinger effect near the boundary in Dirac-Weyl semimetals
M. N. Chernodub, M. A. H. Vozmediano
The electric field inside typical conductors drops down exponentially with the screening length determined by an intrinsic length scale of the system such as the density of mobile…
Anisotropic fixed points in Dirac and Weyl semimetals
Oscar Pozo, Yago Ferreiros, María A. H. Vozmediano
The effective low energy description of interacting Dirac and Weyl semimetals is that of massless quantum electrodynamics with several Lorentz breaking material parameters. We perf…
A Nernst current from the conformal anomaly in Dirac and Weyl semimetals
M. N. Chernodub, A. Cortijo, M. A. H. Vozmediano
We show that a conformal anomaly in Weyl/Dirac semimetals generates a bulk electric current perpendicular to a temperature gradient and the direction of a background magnetic field…
Charge instabilities and topological phases in the extended Hubbard model on the honeycomb lattice with enlarged unit cell
Adolfo G. Grushin, Eduardo V. Castro, Alberto Cortijo +3
We study spontaneous symmetry breaking in a system of spinless fermions in the Honeycomb lattice paying special emphasis to the role of an enlarged unit cell on time reversal symme…
