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…

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…

T-matrix scattering formalism for electron-beam spectroscopy
P. Elli Stamatopoulou, Ulrich Hohenester, Carsten Rockstuhl
Advanced computational tools that describe the interaction of electrons with structured nanophotonic devices are crucial for theoretical predictions, specific design tasks, and the…
