Quantum Electron‐Photon Interactions

Electron-photon interactions are a long-standing important tool in analytical 
microscopy, providing information about the local density of optical or plasmonic modes 
via cathodoluminescence and electron energy-loss spectroscopy. More recently, 
stimulated interactions involving incident optical radiation have enabled the coherent 
modulation of electron wave functions but also opened new pathways for studying a 
plethora of quantum effects such as entanglement, correlations, or decoherence. While 
the instrumentation has typically been based on transmission electron microscopes 
providing ultimate combination of spatial, energy and time resolution, recent years have 
seen a rapid development in the field of ultrafast scanning electron microscopy and 
other methods that utilize low- to moderate-energy electrons to investigate the electron-
light coupling, time-resolved cathodoluminescence, ultrafast low-energy electron 
diffraction and quantum phenomena. The goal of this workshop is to bring together 
experts from this newly emerging field focusing on low- and medium-energy electrons 
with experts from ultrafast transmission electron microscopy and other fields related to 
quantum free-electron-photon interactions. Invited speakers include a well-balanced 
mixture spanning from world-leading senior experts to younger colleagues just starting 
their labs from all over the world. We hope that experienced as well as young researchers 
will participate and enjoy flourishing discussions and interactions - in a beautiful setting 
in the historical center of Prague.
