英文摘要 | By the spin-fermion formula, the Hubbard model on the honeycomb lattice is represented by a U(2) gauge theory using the mean-field method; non-Abelian vortex solutions are constructed based on this theory. The quantization condition shows that the magnetic flux quanta are half-integer. There are 2k bosonic zero modes for the k-winding vortex. For the fermions, there are 2 zero-energy states (ZESs) corresponding to the single elementary vortex. In the vortex core and on the edge, the system is in the semi-metal phase with a spin gap and in the insulator phase with a Neel order, and can be mapped to the superconductor in the class A and CI, respectively.
