Asymptotic correlations in gapped and critical topological phases of 1D quantum systems
Topological phases protected by symmetry can occur in gapped and—surprisingly—in critical systems. We consider non-interacting fermions in one dimension with spinless time-reversal symmetry. It is known that the phases are classified by a topological invariant 𝜔 and a central charge c. We investigat...
