Optimizing the RVB state on a triangular lattice: Presence of the long-range order
Yong-Cong Chen
We present a Schwinger-boson approach for the RVB state of the spin-1/2 Heisenberg antiferromagnet on a triangular lattice. It is shown that Gutzwiller projection of the mean-field…

Optimized RVB states of the 2-d antiferromagnet: Ground state and excitation spectrum
Yong-Cong Chen, Kai Xiu
The Gutzwiller projection of the Schwinger-boson mean-field solution of the 2-d spin-1/2 antiferromagnet in a square lattice is shown to produce the optimized, parameter-free RVB g…
