Lattice model for the surface states of a topological insulator with applications to magnetic and exciton instabilities
D. J. J. Marchand, M. Franz
A surface of a strong topological insulator (STI) is characterized by an odd number of linearly dispersing gapless electronic surface states. It is well known that such a surface c…

Surface magnetic ordering in topological insulators with bulk magnetic dopants
G. Rosenberg, M. Franz
We show that a three dimensional topological insulator doped with magnetic impurities in the bulk can have a regime where the surface is magnetically ordered but the bulk is not. T…
