Ground-State Degeneracy of Correlated Insulators with Edges
Gil Refael, Hsiu-Hau Lin
Using the topological flux insertion procedure, the ground-state degeneracy of an insulator on a periodic lattice with filling factor was found to be at least -fold. App…

Andreev Edge State on Semi-Infinite Triangular Lattice: Detecting the Pairing Symmetry in Na_0.35CoO_2.yH_2O
T. Pereg-Barnea, Hsiu-Hau Lin
We study the Andreev edge state on the semi-infinite triangular lattice with different pairing symmetries and boundary topologies. We find a rich phase diagram of zero energy Andre…
