spin liquid and chiral antiferromagnetic phase in Hubbard model on the honeycomb lattice: duality between Schwinger-fermion and Schwinger-boson representations
Yuan-Ming Lu, Ying Ran
In our previous work, we identify the Sublattice-Pairing State (SPS) in Schwinger-fermion representation as the spin liquid phase discovered in recent numerical study on a honeycom…

Spin liquids on a honeycomb lattice: Projective Symmetry Group study of Schwinger fermion mean-field theory
Yuan-Ming Lu, Ying Ran
Spin liquids are novel states of matter with fractionalized excitations. A recent numerical study of Hubbard model on a honeycomb lattice\cite{Meng2010} indicates that a gapped spi…
