Query: Majorana-Hubbard model on the honeycomb lattice   Phase diagram of a Hubbard model for Majorana fermions on the honeycomb
lattice is explored using a combination of field theory, renormalization group
and mean-field arguments, as well as exact numerical diagonalization. Unlike
the previously studied versions of the model we find that even weak
interactions break symmetries and lead to interesting topological phases. We
establish two topologically nontrivial phases at weak coupling, one gapped with
chiral edge modes, and the other gapless with anti-chiral edge modes. At strong
coupling a mapping onto a novel frustrated spin-${1\over 2}$ model suggests a
highly entangled spin liquid ground state.
