  Title Projective symmetry of partons in the Kitaev honeycomb model Type Journal Article
  Year 2015 Publication Physical Review B Abbreviated Journal Phys. Rev. B  
  Volume 91 Issue 4 Pages 4 pp  
  Abstract Low-energy states of quantum spin liquids are thought to involve partons living in a gauge-field background. We study the spectrum of Majorana fermions of the Kitaev honeycomb model on spherical clusters. The gauge field endows the partons with half-integer orbital angular momenta. As a consequence, the multiplicities do not reflect the point-group symmetries of the cluster, but rather its projective symmetries, operations combining physical and gauge transformations. The projective symmetry group of the ground state is the double cover of the point group.
