Do Truly Unidirectional Surface Plasmon-Polaritons Exist?
S. Ali Hassani Gangaraj, Francesco Monticone
In this work, we revisit the topic of surface waves on nonreciprocal plasmonic structures, and clarify whether strictly unidirectional surface plasmon-polaritons are allowed to exi…
Non-Markovian Transient Casimir-Polder force and population dynamics on excited and ground state atoms: weak and strong coupling regimes in generally non-reciprocal environments
George W. Hanson, S. Ali Hassani Gangaraj, Mario G. Silveirinha +2
The transient Casimir-Polder force on a two-level atom introduced into a three-dimensional, inhomogeneous, generally non-reciprocal environment is evaluated using non-Markovian Wei…
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…
Coupled Topological Surface Modes in Gyrotropic Structures: Green's Function Analysis
S. Ali Hassani Gangaraj, F. Monticone
At a transition in a wave-guiding structure, part of the incident energy is transmitted and part of the energy is reflected. When the waveguide has non-trivial topological properti…
