Velocity-tunable exciton-photon hybridization in cathodoluminescence
Sven Ebel, Martin Nørgaard, Christian Nicolaisen Hansen +2
Exciton-photon hybridization is typically realised in geometrically defined optical cavities, where tunability is achieved by modifying either the cavity or the excitonic medium. H…

Prospects to bypass nonlocal phenomena in metals using phonon-polaritons
Jacob T. Heiden, Eduardo J. C. Dias, Minhyuk Kim +6
Electromagnetic design relies on an accurate understanding of light-matter interactions, yet often overlooks electronic length scales. Under extreme confinement, this omission can…

Near-field refractometry of van der Waals crystals
Martin Nørgaard, Torgom Yezekyan, Stefan Rolfs +3
Common techniques for measuring refractive indices, such as ellipsometry and goniometry, are ineffective for van der Waals crystal flakes because of their high anisotropy and small…
