Broken Time Reversal and Parity Symmetries for Electromagnetic Excitations in Planar Chiral Nanostructures

摘要

We elucidate the physical mechanisms by which electromagnetic excitations inplanar chiral waveguides exhibit broken time reversal and parity symmetries asrecently observed in metallic nanostructures (Phys. Rev. Lett. 91, 247404(2003)). Furthermore, we show that concomitant with these broken symmetries theelectromagnetic excitations can acquire fractional winding numbers, revealinganalogies between light scattering from planar nanostructures and anyon matter.
