Abstract

We present a description of the Kitaev honeycomb lattice model as a BCS type system. A 2-dimensional fermionization procedure is outlined and the derived eigenstates of the system are shown to be Cooper-paired products of toric-code states. We extend our analysis to a torus, giving particular attention to the ground state of the fully periodic vortex-free sector.
