Abstract
We study P,T-breaking physical properties of anyons. Concerning static properties, we find no magnetic field in the anyon superconductor and very small magnetic field in the normal state. Concerning optical properties, we have derived the Wen-Zee–type effective Lagrangian. Therefore anyons exhibit P,T-breaking optical properties without suppression. We conclude that anyon models can be experimentally tested through their P,T-breaking optical properties.
