Higher-order topology in plasmonic kagome lattices
Matthew Proctor, María Blanco de Paz, Dario Bercioux +2
We study the topological properties of a kagome plasmonic metasurface, modelled with a coupled dipole method which naturally includes retarded long range interactions. We demonstra…
Near- and Far-Field Excitation of Topological Plasmonic Metasurfaces
Matthew Proctor, Xiaofei Xiao, Richard V. Craster +3
The breathing honeycomb lattice hosts a topologically non-trivial bulk phase due to the crystalline-symmetry of the system. Pseudospin-dependent edge states which emerge at the int…
On the robustness of topological corner modes in photonic crystals
Matthew Proctor, Paloma Arroyo Huidobro, Barry Bradlyn +4
We analyze the robustness of corner modes in topological photonic crystals, taking a -symmetric breathing honeycomb photonic crystal as an example. First, we employ topologica…
Exciting Pseudospin Dependent Edge States in Plasmonic Metasurfaces
Matthew Proctor, Richard V. Craster, Stefan A. Maier +2
We study a plasmonic metasurface that supports pseudospin dependent edge states confined at a subwavelength scale, considering full electrodynamic interactions including retardatio…
Manipulating Topological Valley Modes in Plasmonic Metasurfaces
Matthew Proctor, Paloma A. Huidobro, Stefan A. Maier +2
The coupled light-matter modes supported by plasmonic metasurfaces can be combined with topological principles to yield subwavelength topological valley states of light. We give a…
