Neutron scattering measurements of cesium chlorocuprate Cs2CuCl4, a spin-1/2 antiferromagnet on a triangular lattice, displayed diffuse scattering. This was attributed to spinons arising from a 2D RVB state. Later theoretical work challenged this picture, arguing that all experimental results were instead consequences of 1D spinons confined to individual chains. WebQUANTUM MATERIALS Quantum spin liquids C. Broholm1, R. J. Cava2, S. A. Kivelson3, D. G. Nocera4, M. R. Norman5*,T. Senthil6 Spin liquids are quantum phases of matter with a variety of unusual features arising from their topological character, including “fractionalization”—elementary excitations that behave as fractions of an electron.
