Abstract

We examine a model which describes the interactions of charged magnetic scalar particles with real gauge fields in 2+1 dimensions. At zero temperature and finite density, in the nonrelativistic mean field limit, the scalar fields have fractional statistics, and the theory contains the Meissner effect. In this limit, our model is effectively a reparametrization of the model that contains a Chern-Simons term for a statistical gauge field and couples the scalar field to the statistical gauge field and a real, dynamical gauge field. At high temperature, our model has a phase transition to the state where magnetic fields penetrate the system.
