We develop an approach to describe antiferromagnetic magnons on a bipartite lattice supporting the N\'{e}el state using fractionalized degrees of freedom typically inherent to quantum spin liquids. In particular we consider a long-range magnetically ordered state of interacting two-dimensional quantum spin-1/2 models using the Chern-Simons (CS) fermion representation of interacting spins. The interaction leads to Cooper instability and pairing of CS fermions, and to CS superconductivity which…

Quantum phase diagram and chiral spin liquid in the extended spin- 12 honeycomb XY model
The frustrated XY model on the honeycomb lattice has drawn lots of attention because of the potential emergence of chiral spin liquid (CSL) with the increasing of frustrations or competing
Helical spin liquid in a triangular XXZ magnet from Chern-Simons theory
We propose a finite-temperature phase diagram for the two-dimensional spin-$1/2$ ${J}_{1}\ensuremath{-}{J}_{2}$ XXZ antiferromagnet on a triangular lattice. Our analysis, based on a composite fermion
