Electrons herald non-classical light
Germaine Arend, Guanhao Huang, Armin Feist +9
Free electrons are a widespread and universal source of electromagnetic fields. The past decades witnessed ever-growing control over many aspects of electron-generated radiation, f…
Tomographic reconstruction of free-electron quantum states
Hao Jeng, Claus Ropers
We give several algorithms for reconstructing quantum states of swift electrons, using maximum likelihood estimation, Bayesian inversion, and deep learning. We apply these algorith…
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…
Femtosecond and attosecond phase-space correlations in few-particle photoelectron pulses
Rudolf Haindl, Valerio Di Giulio, Armin Feist +1
Temporal correlations in pulsed electron beams reflect the microscopic dynamics of emission and interparticle interaction. In femtosecond electron emission from nanoscale field emi…
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…
Observation of quantum entanglement between free electrons and photons
Jan-Wilke Henke, Hao Jeng, Murat Sivis +1
Quantum entanglement is central to both the foundations of quantum mechanics and the development of new technologies in information processing, communication, and sensing. Entangle…
