Beschreibungen/Notizen

• The coupling between dark energy and the pseudoscalar of electromagnetism, if there is any, would induce a rotation of the polarization plane of the cosmic microwave background (CMB). This results in a non-vanishing B-mode and parity-violating TB and EB correlations. Taking into account this effect, we calculate the full set of power spectra of cosmic microwave background (CMB) temperature and polarization anisotropies. We also give the constraint on the coupling strength from WMAP seven year data.
