Fabry-Pérot resonant vortices and magnetoconductance in topological insulator constrictions with magnetic barriers
R. P. Maciel, A. L. Araújo, C. H. Lewenkopf +1
The edge states of two-dimensional time-reversal topological insulators support a perfect helical conductance on wide ribbons due to the absence of backscattering. Here, we study t…
Interplay between boundary conditions and Wilson's mass in Dirac-like Hamiltonians
A. L. Araújo, R. P. Maciel, R. G. F. Dornelas +2
Dirac-like Hamiltonians, linear in momentum , describe the low-energy physics of a large set of novel materials, including graphene, topological insulators, and Weyl fermions. W…
Zitterbewegung and bulk-edge Landau-Zener tunneling in topological insulators
Gerson J. Ferreira, Renan P. Maciel, Poliana H. Penteado +1
We investigate the ballistic zitterbewegung dynamics and the Landau-Zener tunneling between edge and bulk states of wave packets in two-dimensional topological insulators. In bulk,…
