Design of spin-orbital-textures in ferromagnetic/topological insulator interfaces

A. L. Araújo, F. Crasto de Lima, C. H. Lewenkopf +1

Spin-orbital textures in topological insulators due to the spin locking with the electron momentum, play an important role in spintronic phenomena that arise from the interplay bet…

Breakdown of topological protection due to non-magnetic edge disorder in two-dimensional materials in the Quantum Spin Hall phase

Leandro R. F. Lima, Caio Lewenkopf

We study the suppression of the conductance quantization in quantum spin Hall systems by a combined effect of electronic interactions and edge disorder, that is ubiquitous in exfol…

High-energy Landau levels in graphene beyond nearest-neighbor hopping processes: Corrections to the effective Dirac Hamiltonian

Kevin J. U. Vidarte, Caio Lewenkopf

We study the Landau level spectrum of bulk graphene monolayers beyond the Dirac Hamiltonian with linear dispersion. We consider an effective Wannier-like tight-binding model obtain…

Local equilibrium charge and spin currents in two-dimensional topological systems

Leandro R. F. Lima, Caio Lewenkopf

We study the equilibrium and nonequilibrium electronic transport properties of multiprobe topological systems using a combination of the Landauer-Büttiker approach and nonequilibri…
