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…
Roadmap for Quantum Nanophotonics with Free Electrons
F. Javier GarcÃa 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…
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…
