Dielectric laser accelerators (DLAs) are fundamentally based on the interaction of photons
with free electrons, where energy and momentum conservation are satisfied by mediation of …

Quantum light–matter interactions of bound electron systems have been studied extensively.
By contrast, quantum interactions of free electrons with light have only become accessible in …

INTRODUCTION The science of light has undergone two major revolutions over the
previous two centuries. The first—by Grimaldi, Huygens, Fresnel, Young, and Maxwell …

This Letter sets a road map towards an experimental realization of strong coupling between
free electrons and photons and analytically explores entanglement phenomena that emerge …

The last two decades experimentally affirmed the quantum nature of free electron wave
packets by the rapid development of transmission electron microscopes into ultrafast …

It is a long-standing goal to create light with unique quantum properties such as squeezing
and entanglement. We propose the generation of quantum light using free-electron …

We present the quantum theory governing the interaction between short laser pulses and
relativistic free electrons and reveal intrinsic conservation laws for such quantum …

Here we present a new paradigm of free-electron–bound-electron resonant interaction. This
concept is based on a recent demonstration of the optical frequency modulation of the free …

Coherent emission of light by free charged particles is believed to be successfully captured
by classical electromagnetism in all experimental settings. However, recent advances …

How does the quantum-to-classical transition of measurement occur? This question is vital
for both foundations and applications of quantum mechanics. Here, we develop a new …
