Reconfigurable chirality with achiral excitonic materials in the strong-coupling regime
P. Elli Stamatopoulou, Sotiris Droulias, Guillermo P. Acuna +2
We introduce and theoretically analyze the concept of manipulating optical chirality via strong coupling of the optical modes of chiral nanostructures with excitonic transitions in…
Fundamental issues with light propagation through -symmetric systems
Fedor Shuklin, Christos Tserkezis, N. Asger Mortensen +1
We analyse the emergence of unphysical superluminal group velocities in Su--Schrieffer--Heeger (SSH) parity-time () symmetric chains, and explore the origins of such…
Surface-response functions obtained from equilibrium electron-density profiles
N. Asger Mortensen, P. A. D. Gonçalves, Fedor A. Shuklin +4
Surface-response functions are one of the most promising routes for bridging the gap between fully quantum-mechanical calculations and phenomenological models in quantum nanoplasmo…
Atomically Thin Boron Nitride as an Ideal Spacer for Metal-Enhanced Fluorescence
Wei Gan, Christos Tserkezis, Qiran Cai +11
The metal-enhanced fluorescence (MEF) considerably enhances the luminescence for various applications, but its performance largely depends on the dielectric spacer between the fluo…
Manipulating the photonic Hall effect with hybrid Mie-exciton resonances
P. Elli Stamatopoulou, Vassilios Yannopapas, N. Asger Mortensen +1
We examine the far-field optical response, under-plane wave excitation in the presence of a static magnetic field, of core-shell nanoparticles involving a gyroelectric component, e…
Role of diffusive surface scattering in nonlocal plasmonics
Mark. K. Svendsen, Christian Wolff, Antti-Pekka Jauho +2
The recent generalised nonlocal optical response (GNOR) theory for plasmonics is analysed, and its main input parameter, namely the complex hydrodynamic convection-diffusion consta…
