Extreme renormalisations of dimer eigenmodes by strong light-matter coupling
Thomas J. Sturges, Taavi Repän, Charles A. Downing +2
We explore by theoretical means an extreme renormalisation of the eigenmodes of a dimer of dipolar meta-atoms due to strong light-matter interactions. Firstly, by tuning the height…
Polaritonic Tamm states induced by cavity photons
C. A. Downing, L. Martín-Moreno
We consider a periodic chain of oscillating dipoles, interacting via long-range dipole-dipole interactions, embedded inside a cuboid cavity waveguide. We show that the mixing betwe…
Chiral current circulation and symmetry in a trimer of oscillators
Charles A. Downing, David Zueco, Luis Martín-Moreno
We present a simple quantum theory of a bosonic trimer in a triangular configuration, subject to gain and loss in an open quantum systems approach. Importantly, the coupling consta…
Plasmonic modes in cylindrical nanoparticles and dimers
Charles A. Downing, Guillaume Weick
We present analytical expressions for the resonance frequencies of the plasmonic modes hosted in a cylindrical nanoparticle within the quasistatic approximation. Our theoretical mo…
