The present status and development of strong-field nano-optics, an emerging field of
nonlinear optics, is discussed. A nonperturbative regime of light-matter interactions is …

Dipole selection rules underpin much of our understanding in characterization of matter and
its interaction with external radiation. However, there are several examples where these …

For over 80 years of research, the conventional description of free-electron radiation
phenomena, such as Cherenkov radiation, has remained unchanged: classical three …

Strong interaction between light and matter waves, such as electron beams in electron
microscopes, has recently emerged as a new tool for manipulating the electron wave …

Investigating the interaction of electron beams with materials and light has been a field of
research for more than a century. The field was advanced theoretically by the rise of …

Near-field manipulation in plasmonic nanocavities can provide various applications in
nanoscale science and technology. In particular, a gap plasmon in a scanning tunneling …

In electron microscopy, detailed insights into nanoscale optical properties of materials are
gained by spontaneous inelastic scattering leading to electron-energy loss and …

The adiabatic approximation has formed the basis for much of our understandings of the
interaction of light and electrons. The classical nonrecoil approximation or quantum …

Semiconducting transition‐metal dichalcogenides (TMDCs) provide a fascinating discovery
platform for strong light–matter interaction effects in the visible spectrum at ambient …

Transmission electron microscopy is an excellent experimental tool to study the interaction
