Abstract Attosecond spectroscopy,,,,,–can resolve electronic processes directly in time, but a
movie-like space–time recording is impeded by the too long wavelength (~ 100 times larger …

Ultrafast electron and X-ray imaging and spectroscopy are the basis for an ongoing
revolution in the understanding of dynamical atomic-scale processes in matter. The …

Free electron beams such as those employed in electron microscopes have evolved into
powerful tools to investigate photonic nanostructures with an unrivaled combination of …

Particle accelerators are essential tools in science, hospitals and industry,,,,–. Yet their costs
and large footprint, ranging in length from metres to several kilometres, limit their use. The …

Dielectric laser acceleration is a versatile scheme to accelerate and control electrons with
the help of femtosecond laser pulses in nanophotonic structures. We demonstrate here the …

Probing optical excitations with nanometer resolution is important for understanding their
dynamics and interactions down to the atomic scale. Electron microscopes currently offer the …

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 …
