Velocity‐Tunable Exciton‐Photon Hybridization in Cathodoluminescence

Advanced Functional Materials, EarlyView.
Transition‐radiation resonances in suspended thin crystals hybridise with excitonic transitions under free‐electron excitation. By tuning the electron energy, the photonic resonances are continuously detuned across the exciton states, enabling controllable exciton–photon hybridisation below the diffraction limit without altering the system geometry ...

Characteristic energy loss of electrons in Mg with angle resolution

Physics of Complex Systems, 2020
The article discusses electron energy loss of bulk and surface plasmons in solid polycrystalline Mg films. The experimental study of the electrons’ characteristic energy loss is conducted and its results are compared in a wide range of electron incidence

Partially coherent surface plasmon modes [PDF]

Journal of the European Optical Society-Rapid Publications, 2011
Elementary long-range plasmon modes are described assuming an exponential dependence of the refractive index in the neighbourhood of the interface dielectric-metal thin film. The study is performed using coupling mode theory. The interference between two

SURFACE PLASMONS ON A RANDOMLY ROUGH SURFACE

Le Journal de Physique Colloques, 1983
We have studied the dispersion relation for surface plasmons on a randomly rough surface, going beyond the lowest approximation in the surface profile function. The expansion of the surface plasmon dispersion relation in powers of the surface profile function contains an infinite subset of terms that are all of the same order of magnitude as the lowest

Plasmonic Enhancement of Fluorescence and Protein Dynamics in Living Mammalian Cells

Advanced Materials, EarlyView.
This study demonstrates plasmonic enhancement of the function of fluorescent voltage sensing proteins (genetically encoded voltage indicators, (GEVIs), QuasAr6) in live mammalian cells. Coupling to plasmonic nanoparticles does not just increase fluorescence, but influences the protein photocycle, creating a hybrid sensor with its response speed to ...

Path entanglement of surface plasmons

New Journal of Physics, 2015
Metals can sustain traveling electromagnetic waves at their surfaces supported by the collective oscillations of their free electrons in unison. Remarkably, classical electromagnetism captures the essential physics of these ‘surface plasma’ waves using ...
