Abstract

We give a brief review on a family of two dimensional models with continuous symmetry and possibly regular frustration or frustration-type disorder. Next we focus on the random ± J bond XY model. There are two types of variables in this system and thus two candidates for an order parameter, the continuous spin variable and the discrete chiral variable. The question is : do the chiralities order more easily than the spins ? We present an analytical approach based on correlation function studies in one dimension and on domain wall scaling analysis in two dimension. Our results contradict recent interpretation of numerical simulations.
