Spin Hall effect of light in inhomogeneous axion field
Mansoureh Hoseini, Mohammad Mehrafarin
We study the spin transport of light in weakly inhomogeneous axion field in a flat Robertson-Walker universe and derive the spin Hall effect for circularly polarized rays. Regardin…

Cosmological Birefringence and the Geometric Phase of Photons
Mansoureh Hoseini, Mohammad Mehrafarin
Regarding axion electrodynamics in the background flat FRW universe, we show that cosmological birefringence arises from an adiabatic noncyclic geometric phase that appears in the…
