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…
Seebeck and Nernst effects in topological insulator: the case of strained HgTe
Francisco J. Peña, Oscar Negrete, Ning Ma +3
We theoretically study the thermoelectric transport properties of strained HgTe in the topological insulator phase. We developed a model for the system using a Dirac Hamiltonian in…
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…
Valley polarization braiding in strained graphene
D. Faria, C. León, L. R. F. Lima +2
Previous works on deformed graphene predict the existence of valley-polarized states, however, optimal conditions for their detection remain challenging. We show that in the quantu…
A numerical method to efficiently calculate the transport properties of large systems: an algorithm optimized for sparse linear solvers
Tatiane P. Santos, Leandro R. F. Lima, Caio H. Lewenkopf
We present a self-contained description of the wave-function matching (WFM) method to calculate electronic quantum transport properties of nanostructures using the Landauer-Büttike…
Investigating transverse Hall conductances using two-terminal setups
Alexis R. Hernández, Leandro R. F. Lima
In this paper we present a method to numerically study transverse Hall conductances using a two-terminal setup. Using nonlinear transport concepts we find that the Hall voltage dep…
