Global phase diagram and quantum spin liquids in spin-1/2 triangular antiferromagnet

Shou-Shu Gong, W. Zhu, J. -X. Zhu +2

We study the spin-$1/2$ Heisenberg model on the triangular lattice with the nearest-neighbor $J_1>0$, the next-nearest-neighobr $J_2>0$ Heisenberg interactions, and the additio…
