Bound fermion states in pinned vortices in the surface states of a superconducting topological insulator: The Majorana bound state

Haoyun Deng, Nicholas Bonesteel, Pedro Schlottmann

By analytically solving the Bogoliubov-de Gennes equations we study the fermion bound states at the center of the core of a vortex in a two-dimensional superconductor. We consider…
