Full quantitative near-field characterization of strongly coupled exciton-plasmon polaritons in thin-layered WSe2 on a monocrystalline gold platelet
Laura N. Casses, Binbin Zhou, Qiaoling Lin +6
Exciton-plasmon polaritons (EPPs) are attractive both for the exploration of fundamental phenomena and applications in nanophotonics. Previous studies of EPPs mainly relied on far-…

Moiré superlattices in van der Waals heterostructures offer highly tunable quantum systems with emergent electronic and excitonic properties such as superconductivity, topological…
Combining experiments on luminescent centres in hexagonal boron nitride with the polaron model and ab initio methods towards the identification of their microscopic origin
Moritz Fischer, Ali Sajid, Jake Iles-Smith +10
The two-dimensional material hexagonal boron nitride (hBN) hosts luminescent centres with emission energies of 2 eV which exhibit pronounced phonon sidebands. We investigate the mi…
Signatures of Non-Markovianity in Cavity-QED with Color Centers in 2D Materials

Nanometer-scale photon confinement in topology-optimized dielectric cavities
Marcus Albrechtsen, Babak Vosoughi Lahijani, Rasmus Ellebæk Christiansen +8
Nanotechnology enables in principle a precise mapping from design to device but relied so far on human intuition and simple optimizations. In nanophotonics, a central question is h…
The importance of substrates for the visibility of "dark" plasmonic modes
Saskia Fiedler, Søren Raza, Ruoqi Ai +5
Dark plasmonic modes have interesting properties, such as a longer lifetime and a narrower linewidth than their radiative counterpart, as well as little to no radiative losses. How…
