Unidirectional and diffractionless surface plasmon-polaritons on three-dimensional nonreciprocal plasmonic platforms
S. Ali Hassani Gangaraj, George W. Hanson, Mario G. Silveirinha +3
Light-matter interactions in conventional nanophotonic structures typically lack directionality. Furthermore, surface waves supported by conventional material substrates do not usu…
Optical torque on a two-level system near a strongly nonreciprocal medium
S. Ali Hassani Gangaraj, Mário G. Silveirinha, George W. Hanson +2
We investigate the quantum optical torque on an atom interacting with an inhomogeneous electromagnetic environment described by the most general linear constitutive relations. The…
Momentum-Space Topological Effects of Nonreciprocity
S. Ali Hassani Gangaraj, George W. Hanson
The connection between topology and nonreciprocity in photonic systems is reviewed. Topological properties such as Chern number, and momentum-space properties such as Berry phase a…
