Supersymmetry in the Fractional Quantum Hall Regime
Eran Sagi, Raul A. Santos
Supersymmetry (SUSY) is a symmetry transforming bosons to fermions and vice versa. Indications of its existence have been extensively sought after in high-energy experiments. Howev…
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…
Negativity in the Generalized Valence Bond Solid State
Raul A. Santos, V. Korepin
Using a graphical presentation of the spin one dimensional Valence Bond Solid (VBS) state, based on the representation theory of the Lie-algebra of spins, we compute th…
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…
