  The rotation of polarization occurs for light interacting with chiral
materials. It requires the light states with opposite chiralities interact
differently with the materials. We demonstrate analogous rotation of
polarization also exists for chiral fermions interacting with quantum
electrodynamics plasma with vorticity using chiral kinetic theory. We find that
the rotation of polarization is perpendicular both to vorticity and fermion
momentum. The effect also exists for chiral fermions in quantum chromodynamics
plasma with vorticity. It could lead to generation of a vector current when the
probe fermions contain momentum anisotropy.
