CPT conserving cosmological birefringence

  title={CPT conserving cosmological birefringence},
  author={Chao-Qiang Geng and S. H. Ho and John N. Ng},
  journal={arXiv: Astrophysics},
We demonstrate that the cosmological birefringence can arise from CPT conserving effect, originated from the CPT-even dimension-six Chern-Simons-like term. We show that a sizable rotation polarization angle in the data of the cosmic microwave background radiation polarization can be induced.

Cosmological birefringence due to CPT-even Chern–Simons-like term with Kalb–Ramond and scalar fields
We study the CPT-even dimension-six Chern–Simons-like term by including dynamical Kalb–Ramond and scalar fields to examine the cosmological birefringence. We show that the combined effect of aExpand

Tests of discrete symmetries
This article provides a coarse-grained review on the experimental tests of fundamental discrete symmetries, focusing on those which appear to be deeply ingrained in nature, or at least rooted intoExpand
Birefringence induced by pp-wave modes in an electromagnetically active dynamic aether
In the framework of the Einstein–Maxwell-aether theory we study the birefringence effect, which can occur in the pp-wave symmetric dynamic aether. The dynamic aether is considered to be a latentlyExpand


Cosmological birefringence induced by neutrino current
We review our recent work, Geng et al. (J. Cosmol. Astropart. Phys. 09, 010 (2007)) on the cosmological birefringence. We propose a new type of effective interactions in terms of the CPT-evenExpand
Searching for CPT violation with cosmic microwave background data from WMAP and BOOMERANG.
It is found that a nonzero rotation angle of the photons is mildly favored and if the Lorentz and symmetries are broken by a Chern-Simons term in the effective Lagrangian, the polarization vectors of propagating CMB photons will get rotated. Expand
Cosmic ray and neutrino tests of special relativity
Abstract Searches for anisotropies due to Earth's motion relative to a preferred frame — modern versions of the Michelson-Morley experiment — provide precise verifications of special relativity. WeExpand
Constraints on CPT violation from Wilkinson Microwave Anisotropy Probe three year polarization data: A wavelet analysis
We perform a wavelet analysis of the temperature and polarization maps of the cosmic microwave background (CMB) delivered by the Wilkinson Microwave Anisotropy Probe experiment in search for aExpand
A nearly-massless, slowly-rolling scalar field $\phi$ may provide most of the energy density of the current universe. One potential difficulty with this idea is that couplings to ordinary matter,Expand
Topological mass generation in four dimensions.
This formulation offers a unified topological description of some seemingly unrelated phenomena, such as two-dimensional superconductivity, and the generation of eta' and axion masses by QCD, and possibly by gravity. Expand
Some tests on CPT invariance
We first briefly review tests on CPT invariance based on the consequences of the CPT theorem and then present some possible CPT tests due to exotic models in which some of the CPT conditions areExpand
Empirical Foundations of the Relativistic Gravity
In 1859, Le Verrier discovered the mercury perihelion advance anomaly. This anomaly turned out to be the first relativistic-gravity effect observed. During the 141 years to 2000, the precisions ofExpand
