Radiative toroidal dipole and anapole excitations in collectively responding arrays of atoms
Kyle E. Ballantine, Janne Ruostekoski
A toroidal dipole represents an often overlooked electromagnetic excitation distinct from the standard electric and magnetic multipole expansion. We show how a simple arrangement o…

Optical Magnetism and Huygens' Surfaces in Arrays of Atoms Induced by Cooperative Responses
K. E. Ballantine, J. Ruostekoski
By utilizing strong optical resonant interactions in arrays of atoms with electric dipole transitions, we show how to synthesize collective optical responses that correspond to tho…
