Spectral Anisotropy in Transition Radiation from Biaxial Media
Sven Ebel, Bibi Mary Francis, Min Seok Jang +4
In anisotropic optical media, the electromagnetic response depends on the orientation of the optical field relative to the material's principal dielectric axes. While this directio…
Controlling Electron-Beam-Induced Charging in Colloidal Quantum Dots
Sven Ebel, Alina Myslovska, Stefano Vezzoli +2
Colloidal quantum dots (QDs) are attractive nanoscale emitters, yet their cathodoluminescence (CL) response remains poorly understood and often unstable under electron-beam excitat…
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…
Stimulated interactions of low-energy free-electrons with light
Fatemeh Chahshouri, Sven Ebel, Mitja Funk +1
Free-electron interactions with light and matter have long served as a cornerstone for exploring the quantum and ultrafast dynamics of material excitation. In recent years, this pa…
Substrate-Assisted Cathodoluminescence
Sven Ebel, N. Asger Mortensen, Sergii Morozov
Electron-beam-induced luminescence typically relies on direct excitation by high energy primary electrons. Here, we explore properties of an alternative excitation approach where c…
An atlas of photonic and plasmonic materials for cathodoluminescence microscopy
Sven Ebel, Yonas Lebsir, Torgom Yezekyan +2
Cathodoluminescence (CL) microscopy has emerged as a powerful tool for investigating the optical properties of materials at the nanoscale, offering unique insights into the behavio…
Structured free-space optical fields for transverse and longitudinal control of electron matter waves
Sven Ebel, Nahid Talebi
Controlling free-electron momentum states is of high interest in electron microscopy to achieve momentum and energy resolved probing and manipulation of physical systems. Free-elec…
Inelastic Electron Scattering at a Single-Beam Structured Light Wave
Sven Ebel, Nahid Talebi
In this work we demonstrate the inelastic scattering of slow-electron wavepackets at a propagating Hermite-Gaussian light beam. The pulsed Hermite-Gaussian beam thereby forms a pon…
