Time- and frequency-domain study for electron beams penetrating dielectric nanospheres: fingerprints of Cherenkov and transition radiation
Wenhua Zhao, Christos Tserkezis, N. Asger Mortensen +1
We present a theoretical study of Cherenkov and transition radiation for swift electron beams penetrating dielectric nanospheres using material models of different sophistication.…
Probe- and Substrate-Dependent Visibility of Mie Resonances in Silicon Nanospheres
Yonas Lebsir, Huatian Hu, P. A. D. Gonçalves +5
Silicon nanospheres are high-quality optical resonators and promising building blocks for Mie-tronic devices. While the Mie resonances of an isolated sphere are well understood, pr…
Probing strong coupling in core--shell nanoparticles with fast electron beams
Annika Brandt, Christos Tserkezis, Carsten Rockstuhl +1
Collective optical excitations, such as localized surface plasmons in metallic nanoparticles and Mie resonances in high-index dielectrics, play a central role in nanoscale light--m…
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…
Magnetic and Electric Mie-Exciton Polaritons in Silicon Nanodisks
Francesco Todisco, Radu Malureanu, Christian Wolff +4
Light-matter interactions at the nanoscale constitute a fundamental ingredient for engineering applications in nanophotonics and quantum optics. To this regard electromagnetic Mie…
On the time evolution at a fluctuating exceptional point
Christian Wolff, Christos Tserkezis, N. Asger Mortensen
We theoretically evaluate the impact of drift-free noise on the dynamics of -symmetric non-Hermitian systems with an exceptional point, which have recently been propo…
