Geometric frustration on the triangular lattice prevents long-range magnetic order even at T=0. The ground state is a quantum superposition of singlet configurations — a quantum spin liquid with fractionalized excitations.

At J₂/J₁ ≈ 0.06–0.17: possible QSL. The structure factor shows diffuse scattering (no sharp Bragg peaks), a hallmark of spin liquid disorder with hidden long-range entanglement.
