Topological Order in Projected Wave Functions and Effective Theories of Quantum Antiferromagnets

Tao Li, Hong-Yu Yang

We study the topological order in RVB state derived from Gutzwiller projection of BCS-like mean field state. We propose to construct the topological excitation on the projected RVB…
