When impinging on optical structures or passing in their vicinity, free electrons can
spontaneously emit electromagnetic radiation, a phenomenon generally known as …

Flatbands have become a cornerstone of contemporary condensed-matter physics and
photonics. In electronics, flatbands entail comparable energy bandwidth and Coulomb …

Particles at relativistic energies form the basis of acceleration science. The emergence of
terahertz-driven acceleration promises vastly smaller and cost-efficient accelerators; …

Electron microscopy and diffraction with ultrashort pulsed electron beams are capable of
imaging transient phenomena with the combined ultrafast temporal and atomic-scale spatial …

Integrated photonics facilitates extensive control over fundamental light–matter interactions
in manifold quantum systems including atoms, trapped ions,, quantum dots and defect …

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 …

Recently, integrated photonic circuits have brought new capabilities to electron microscopy
and been used to demonstrate efficient electron phase modulation and electron-photon …

We demonstrate a silicon-based electron accelerator that uses laser optical near fields to
both accelerate and confine electrons over extended distances. Two dielectric laser …
