Description
In this talk, we discuss the electroweak (EW) axion quintessence dark energy in light of the recently reported non-zero rotation angle of the cosmic microwave background (CMB) linear polarization β=0.35±0.14deg. We further discuss the model's prediction on the equation of state of EW axion dark energy with the aid of the cosmic birefringence.
