英文摘要	Searching for spin liquids on the honeycomb J(1-J2) Heisenberg model has been attracting great attention in the past decade. In this Paper we investigate the topological properties of the J(1-J2) Heisenberg model by introducing nearest-neighbour and next-nearest-neighbour bond parameters. We find that there exist two topologically different phases in the spin disordered regime 0.2 < J(2)/J(1) < 0.5: for J(2)/J(1) < 0.32, the system is a zero-flux spin liquid which is topological trivial and gapless; for J(2)/J(1) > 0.32, it is a pi/2-flux chiral spin liquid, which is topological nontrivial and gapped. These results suggest that there exist two topologically different spin disorder phases in honeycomb J(1-J2) Heisenberg model.
