Universal magnetic properties of frustrated quantum antiferromagnets in two dimensions
Abstract
We present a theory of frustrated, two-dimensional, quantum antiferromagnets in the vicinity of a quantum transition from a noncollinear, 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.
