Recent analysis of CMB polarization data from Planck satellite suggests a hint of a new signal, isotropic cosmic birefringence, which is found through a parity-violating correlation between the E- and B-mode polarization. We investigate the possibility that axion-like particles (ALPs) account for the isotropic birefringence via the party-violating Chern-Simons coupling to photons. Especially when the ALP is responsible for dark energy, it is possible to probe the tiny deviation of the dark energy equation of state from −1 through the cosmic birefringence. We also explore ALPs working as early dark energy, which alleviates the Hubble tension problem.
