RVB gauge theory and the Topological degeneracy in the Honeycomb Kitaev model

Saptarshi Mandal, R. Shankar, G. Baskaran

We relate the Z${}_2$ gauge theory formalism of the Kitaev model to the SU(2) gauge theory of the resonating valence bond (RVB) physics. Further, we reformulate a known Jordan-Wigner…
