First principles study of topological invariants of Weyl points in continuous media
G. R. Fonseca, F. R. Prudêncio, M. G. Silveirinha +1
In recent years there has been a great interest in topological photonics and protected edge states. Here, we present a first principles method to compute topological invariants of…
Robust surface plasmon polaritons on gyrotropic interfaces
Samaneh Pakniyat, Alexander M. Holmes, George W. Hanson +5
Unidirectional surface plasmon polaritons (SPPs) at the interface between a gyrotropic medium and a simple medium are studied in a newly-recognized frequency regime wherein the SPP…
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…
Spontaneous lateral atomic recoil force close to a photonic topological material
S. Ali Hassani Gangaraj, George W. Hanson, Mauro Antezza +1
We investigate the quantum recoil force acting on an excited atom close to the surface of a nonreciprocal photonic topological insulator (PTI). The main atomic emission channel is…
Fluctuation-induced forces on an atom near a photonic topological material
Mário G. Silveirinha, S. Ali Hassani Gangaraj, George W. Hanson +1
We theoretically study the Casimir-Polder force on an atom in a arbitrary initial state in a rather general electromagnetic environment wherein the materials may have a nonreciproc…
