Polarization Rotation of Chiral Fermions in Vortical Fluid

Understand

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.
