unification and the large-N theory of superconductor-insulator transition of two-dimensional Dirac fermions
Igor F. Herbut, Subrata Mandal
Electrons on honeycomb or pi-flux lattices obey effective massless Dirac equation at low energies and at the neutrality point, and should suffer quantum phase transitions into vari…

RVB gauge theory and the Topological degeneracy in the Honeycomb Kitaev model
Saptarshi Mandal, R. Shankar, G. Baskaran
We relate the Z 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…
