Abstract: We present a model for a system involving a photon gauge field and a scalarfield at quantum criticality in the frame of a Lifthitz-type non-relativisticMaxwell theory. We will show this model gives rise to Lorentz and CPT violationwhich leads to a frequency-dependent rotation of polarization plane ofradiations, and so leaves potential signals on the cosmic microwave backgroundtemperature and polarization anisotropies.
