摘要：

We perform a general symmetry analysis of optical experiments on samples in the "PT state," that is, samples for which 3D inversion symmetry P and time inversion symmetry T are each broken, but which are invariant under the product PT. We show that PT symmetry is compatible with all known results on optical rotation in the high-temperature superconductors. We also find a unique and accessible experimental signature for the PT state.
