Description:
Author(s): Xie Chen, Lukasz Fidkowski, and Ashvin Vishwanath The surfaces of three-dimensional topological insulators (3D TIs) are generally described as Dirac metals, with a single Dirac cone. It was previously believed that a gapped surface implied breaking of either time-reversal T or U(1) charge conservation symmetry. Here, we discuss a possibility in the... [Phys. Rev.
