英文摘要	We present a projector quantum Monte Carlo study of the topological properties of the valence-bond-solid groinid state in the J-Q(3) spin model oil the square lattice. The winding number is a topological number counting the number of domain walls hi the system and is a good quantum number in the thermodynamic limit. We study the finite-size behavior and obtain the domain wall energy density for a topological nontrivial valence-bond-solid state.
