Abstract: We describe neutron scattering, NMR relaxation, and thermal transport properties of \(Z_2\) spin liquids in two dimensions. Comparison to recent experiments on the spin \(S=\frac{1}{2}\) triangular lattice antiferromagnet in \(\kappa-(ET)_2Cu_2(CN)_3\) shows that this compound may realize a \(Z_2\) spin liquid. We argue that the topological `vison' excitations dominate thermal transport, and that recent thermal conductivity experiments by M. Yamashita et al. have observed the vison gap.
