Valence bond spin liquid state in two-dimensional frustrated spin-1/2 Heisenberg antiferromagnets

Guang-Ming Zhang, Hui Hu, Lu Yu

Fermionic valence bond approach in terms of SU(4) representation is proposed to describe the $J_{1} - J_{2}$ frustrated Heisenberg antiferromagnetic (AF) model on a {\it bipartite} s…

Generalized Schwinger boson mean field theory for two-dimensional SU(4) symmetric spin-orbital antiferromagnet

Guang-Ming Zhang

A generalized Schwinger boson representation is proposed to describe the two-dimensional SU(4) symmetric spin-orbital quantum antiferromagnet. A uniform mean field solution gives r…
