Vanishing Wilson ratio as the hallmark of quantum spin-liquid models
We present numerical results for finite-temperature T>0 thermodynamic quantities, entropy s(T), uniform susceptibility χ_{0}(T), and the Wilson ratio R(T), for several isotropic S=1/2 extended Heisenberg models, which are prototype models for planar quantum spin liquids. We consider in this conte...
