Fabry-P\'erot resonant vortices and magnetoconductance in topological insulator constrictions with magnetic barriers

Autor: Caio H. Lewenkopf, Renan Maciel, Augusto L. Araújo, Gerson J. Ferreira

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 the changes in the transport properties of topological insulator nanori

Introdução : A prevalência de doenças alérgicas, como asma, rinite e eczema, tem aumentado nas últimas décadas em países desenvolvidos. Em média, acomete 200 a 300 milhões de indivíduos, sendo as doenças crônicas mais comuns entre as cri

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, we use the Ehrenfest theorem to show that an external in-plane electr
