Local density of states in two-dimensional topological superconductors under a magnetic field: Signature of an exterior Majorana bound state

We study quasiparticle states on a surface of a topological insulator (TI) with proximity-induced superconductivity under an external magnetic field. An applied magnetic field creates two Majorana bound states: a vortex Majorana state localized inside a vortex core and an exterior Majorana state loc...
