Breaking up the Anapole: or How to Separate Toroidal and Electric Dipole Excitations in Matter

Not Accessible

Your library or personal account may give you access

Abstract

Increasing interest in electrodynamics and spectroscopy of toroidal excitations in matter has initiated a discussion on independent physical significance of toroidal and electric dipole excitations. Here we introduce three Gedanken-Experiments that reveal their fundamental differences.
