Chiral spin liquid with spinon Fermi surfaces in spin-$1/2$ triangular Heisenberg model

Shou-Shu Gong, Wayne Zheng, Mac Lee +2

We study the interplay of competing interactions in spin-$1/2$ triangular Heisenberg model through tuning the first- ($J_1$), second- ($J_2$), and third-neighbor ($J_3$) couplings.…
