Abstract

We study 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. The general scaling properties of this transition are described. A detailed study of a particular field-theoretic model of the transition, with bosonic spin- 1 2 spinon fields, is presented. Explicit universal scaling forms for a variety of observables are obtained and the results are compared with numerical data on the spin- 1 2 triangular antiferromagnet. Universal properties of an alternative field theory, with confined spinons, are also briefly noted.
