SU(2) Slave Fermion Solution of the Kitaev Honeycomb Lattice Model
We apply the SU(2) slave fermion formalism to the Kitaev honeycomb lattice
model. We show that both the Toric Code phase (the A phase) and the gapless
phase of this model (the B phase) can be identified with p-wave superconducting
phases of the slave fermions, with nodal lines which, respectively, do not or
do intersect the Fermi surface. The non-Abelian Ising anyon phase is a
superconducting phase which occurs when the B phase is subjected to a
gap-opening magnetic field. We also discuss the transitions between these
phases in this language
