Universal Magnetic Properties of Frustrated Quantum Antiferromagnets in Two Dimensions
arXiv:cond-mat/9311045 · doi:10.1103/PhysRevLett.72.2089
Abstract
We present a theory of frustrated, two-dimensional, quantum antiferromagnets in the vicinity of a quantum transition from a non-collinear, magnetically-ordered ground state to a quantum-disordered phase. Using a sigma-model for bosonic, spin-1/2, spinon fields, we obtain universal scaling forms for a variety of observables. Our results are compared with numerical data on the spin-1/2 triangular antiferromagnet.
