Abstract
The resonating-valence-bond (RVB) theory for two-dimensional quantum antiferromagnets is shown to be the correct paradigm for large enough “quantum frustration.” This scenario, proposed a long time ago but never confirmed by microscopic calculations, is strongly supported by a new type of variational wave function, which is extremely close to the exact ground state of the Heisenberg model for . This wave function is proposed to represent the generic spin-half RVB ground state in spin liquids.
