Magnetic field induced localization in 2D topological insulators
Pierre Delplace, Jian Li, Markus Büttiker
Localization of the helical edge states in quantum spin Hall insulators requires breaking time reversal invariance. In experiments this is naturally implemented by applying a weak…
Topological Weyl Semi-metal from a Lattice Model
Pierre Delplace, Jian Li, David Carpentier
We define and study a three dimensional lattice model which displays a Weyl semi-metallic phase. This model consists of coupled layers of quantum (anomalous) Hall insulators. The W…
Scattering theory of chiral Majorana fermion interferometry
Jian Li, Geneviève Fleury, Markus Büttiker
Using scattering theory, we investigate interferometers composed of chiral Majorana fermion modes coupled to normal metal leads. We advance an approach in which also the basis stat…
