Testing the Lorentz and CPT Symmetry with CMB polarizations and a non-relativistic Maxwell Theory
arXiv:0912.3317 · doi:10.1088/1475-7516/2010/01/017
Abstract
We present a model for a system involving a photon gauge field and a scalar field at quantum criticality in the frame of a Lifthitz-type non-relativistic Maxwell theory. We will show this model gives rise to Lorentz and CPT violation which leads to a frequency-dependent rotation of polarization plane of radiations, and so leaves potential signals on the cosmic microwave background temperature and polarization anisotropies.
