3-form dark energy can explain cosmic birefringence with a dimension-4 photon coupling, yielding redshift profiles that can mimic or differ from axion dark energy, but the implied photon mass estimate is numerically shaky.
The two circular polarization modes propagate with different phase veloc- ities, leading to the rotation of the polarization angle and cosmic birefringence
