Green's function topology of Majorana wires
We represent the $\mathbb {Z}_2$ topological invariant characterizing a one-dimensional topological superconductor using a Wess–Zumino–Witten dimensional extension. The invariant is formulated in terms of the single-particle Green's function which allows us to classify interacting systems. Employing...
