Beyond the bulk-edge correspondence, we find the ground state degeneracy of the fully gapped edge modes depends on boundary gapping ...
A gapless edge is significantly richer than a gapped edge because gapless edge modes are described by 1+1D rational conformal field theories (RCFT's) [8], [80], ...
We derive a formula for the topological ground state degeneracy of such a TRS- FTL, which applies to cases where the edge modes on each ...
The fully gapped edges carry a topological degree of freedom that can
We derive a formula for the topological ground-state degeneracy of such a TRS- FTL, which applies to cases where the edge modes on each ...
First, what kinds of nonchiral topological orders provide gapped boundary edge modes, for example by introducing interaction terms? We will ...
Despite the absence of a bulk gap, these edge modes are robust against arbitrary symmetry-preserving local perturbations near the edges. In two ...
Gapped domain walls, as topological line defects between (2+1)D
which applies to cases where the edge modes on each boundary are fully gapped by ...
