Emergent topological excitations in a two-dimensional quantum spin system
Hui Shao, Wenan Guo, Anders W. Sandvik
We study the mechanism of decay of a topological (winding-number) excitation due to finite-size effects in a two-dimensional valence-bond solid state, realized in an spin m…

Topological properties of a Valence-Bond-Solid
Hui Shao, WenAn Guo, Anders W. Sandvik
We present a projector quantum Monte Carlo study of the topological properties of the valence-bond-solid ground state in the - spin model on the square lattice. The winding…
