Interaction induced topological protection in one-dimensional conductors
Nikolaos Kainaris, Raul A. Santos, D. B. Gutman +1
We discuss two one-dimensional model systems -- the first is a single channel quantum wire with Ising anisotropy, while the second is two coupled helical edge states. We show that…

Phase diagram of two interacting helical states
Raul A. Santos, D. B. Gutman, Sam T. Carr
We consider two coupled time reversal invariant helical edge modes of the same helicity, such as would occur on two stacked quantum spin Hall insulators. In the presence of interac…
