An S-matrix Formalism for the Nonclassical Optical Response of Plasmonic Nanowires
Xin Zheng, Christos Tserkezis, Christos Mystilidis +2
This paper reports a computational scheme which predicts the light-matter interaction in multiple mesoscopic plasmonic nanowires (NWs), each of which includes concentric or eccentr…
Surface quantum response of plasmonic heterodimers: revealing the hidden nonlocality
Ida Juliane Bundgaard, Christos Mystilidis, Frederik Wulff Christensen +7
We probe the quantum response of plasmonic heterodimers with extended (plane waves) and localized (point dipoles and electron beams) sources. Implementing the surface-response form…
Gibbs Phenomenon and Friedel Oscilations: Similarities, Differences, and the Educational Potential of their Comparison
Christos Mystilidis, Christos Tserkezis, George Fikioris
We explore the similarities and differences between the Gibbs phenomenon in partial Fourier representations of discontinuous signals and Friedel oscillations in the electron densit…
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…
Microscopic screening theory for excitons in two-dimensional materials: A bridge between effective models and ab initio descriptions
P. Ninhos, A. J. Uría-Álvarez, C. Tserkezis +2
We present a computational approach for exciton calculations in two-dimensional (2D) materials within the Bethe-Salpeter equation (BSE) framework, employing an atomistic descriptio…
