Abstract
We describe how the Kitaev honeycomb model with a finite number
of sites on a torus may be easily generalised to cylindrical and rectangular
topologies using a recently developed fermionisation technique. We then look
for criteria which determine if zero-energy modes exist for these cases in the
absence of an external magnetic field. For the cylindrical case, we determine the
combination of spin–spin coupling strengths and vortex configurations which give
zero modes and construct them explicitly, and for the rectangular case we show
that no zero modes can exist.
