Gapped Dirac cones and spin texture in thin film topological insulator
The protected surface states of topological insulators (TIs) form gapless Dirac cones corresponding nondegenerate eigenstates with helical spin polarization. The presence of a warping term deforms the isotropic cone of the most simple model into snowflake Fermi surfaces as in Bi_{2}Se_{3} and Bi_{2}...
