We show how the index of the fermion operator from the euclidean action can be used to uncover the existence of gapless modes living on defects (such as edges and vortices) in topological insulators and superconductors. Abstract: we generalize the idea of the quantized hall current to count gapless edge states in topological materials, applying equally well to theories in diferent di mensions, with or without continuous symmetries in the bulk or chiral anomalies on the boundaries. We show how the index of the fermion operator from the euclidean action can be used to uncover the existence of gapless modes living on defects (such as edges and vortices) in topological.

Abstract: we generalize the idea of the quantized hall current to count gapless edge states in topological materials, applying equally well to theories in diferent di mensions, with or without continuous symmetries in the bulk or chiral anomalies on the boundaries. We show how the index of the fermion operator from the euclidean action can be used to uncover the existence of gapless modes living on defects (such as edges and vortices) in topological. In both cases, the generalized hall current correctly produces the index of the fermion operator and counts the number of massless fermions in minkowski pace. we then discuss dirac fermion in 2 1 dimensions, which exhibits the integer quantum hall effect, with the in flow anomaly. Gapped fermion theories with gapless boundary fermions can exist in any number of dimensions. when the boundary has even space time dimensions and hosts chiral fermions, a quantum hall current flows from the bulk to the boundary in a background electric field.
