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 interactions. In this paper, we study the extended spin-$\frac{1}{2}$ XY model with nearest-neighbor $({J}_{1})$, and next-nearest-neighbor $({J}_{2})$ interactions in the presence of a three-spins chiral $({J}_{\ensuremath{\chi}})$ term using density matrix renormalization group methods. We obtain a quantum… 
Spontaneous chiral-spin ordering in spin-orbit coupled honeycomb magnets
Frustrated magnets with highly degenerate ground states are at the heart of hunting exotic states of matter. Recent studies in spin-orbit coupled honeycomb magnets have generated immense interest in
Schwinger-Boson mean-field study of spin-1/2 $J_1$-$J_2$-$J_{\chi}$ model in honeycomb lattice: thermal Hall signature
We theoretically investigate, within the Schwinger-Boson mean-field theory, the transition from a gapped Z2 quantum spin-liquid, in a J1-J2 Heisenberg spin-1/2 system in a honeycomb lattice, to a
