Nearly flat Andreev bound states in superconductor-topological insulator hybrid structures
Mahmoud Lababidi, Erhai Zhao
Exotic excitations arise at the interface between a three-dimensional topological insulator (TI) and superconductors. For example, Majorana fermions with a linear dispersion, $E\si…

Mott scattering at the interface between a metal and a topological insulator
Erhai Zhao, Chun Zhang, Mahmoud Lababidi
We compute the spin-active scattering matrix and the local spectrum at the interface between a metal and a three-dimensional topological band insulator. We show that there exists a…
