Magnetic warping in topological insulators
We analyze the electronic structure of topological surface states in the family of magnetic topological insulators MnBi_{2n}Te_{3n+1}. We show that, at natural-cleavage surfaces, the Dirac cone warping changes its symmetry from hexagonal to trigonal at the magnetic ordering temperature. In particula...
