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…
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…
Topological Wave-Guiding Near an Exceptional Point: Defect-Immune, Slow-Light, Loss-Immune Propagation
S. Ali Hassani Gangaraj, Francesco Monticone
Electromagnetic waves propagating, at finite speeds, in conventional wave-guiding structures are reflected by discontinuities and decay in lossy regions. In this Letter, we drastic…
Trapping Light in Plain Sight: Embedded Photonic Eigenstates in Zero-Index Metamaterials
Francesco Monticone, Hugo M. Doeleman, Wouter Den Hollander +2
Confining electromagnetic energy is crucial to enhance light-matter interactions, with important implications for science and technology. Here, we discuss the opportunities offered…
