Cathodoluminescence Enhancement Mechanisms in Silica Microspheres
Hadar Aharon, Zahava Barkay, Sophie Meuret +1
Cathodoluminescence (CL) enables optical-frequency analysis of samples with nanometer resolutions, originating from the interaction of a focused electron beam with radiative electr…
Elastic Quantum Coupling Between Free Electrons and Photons
Dingguo Zheng, Ofer Kfir
The quantum coupling between free-electrons and photons enables applying quantum optics techniques in electron microscopy. Here, we formulate the elastic electron-photon quantum co…
Revealing domain wall stability during ultrafast demagnetization
Hung-Tzu Chang, Sergey Zayko, Timo Schmidt +5
The ultrafast control of nanoscale spin textures such as magnetic domain walls or skyrmions is essential for advancing high-speed, high-density spintronics. However, imaging their…
Light's symmetry, asymmetry, and their role in nonlinear optics and ultrafast phenomena
Ofer Neufeld, Matan Even Tzur, Ofer Kfir +2
The analysis of symmetries is extremely useful across science. In Physics, symmetries are used to derive conservation laws and selection rules for transitions in interacting system…
Roadmap for Quantum Nanophotonics with Free Electrons
F. Javier García de Abajo, Albert Polman, Cruz I. Velasco +44
Over the past century, continuous advancements in electron microscopy have enabled the synthesis, control, and characterization of high-quality free-electron beams. These probes ca…
