New search methods for axions by using the photon's birefringence effect

Description

Abstract: Axions are the promising candidate for the dark sector of our universe. Most of the previous axion searches were based on the axion-photon conversion under the background magnetic field. Recently, however, new search methods for axions have been proposed based on the photon's birefringence effect, without using external magnetic fields. In this talk, we introduce how to search for this effect by the use of optical interferometers or CMB polarization measurements.
