Electron migration in molecules is the progenitor of chemical reactions and biological
functions after light-matter interaction. Following this ultrafast dynamics, however, has been …

The microscopic valence electron density determines the optical, electronic, structural and
thermal properties of materials. However, current techniques for measuring this electron …

During femtosecond laser fabrication, photons are mainly absorbed by electrons, and the
subsequent energy transfer from electrons to ions is of picosecond order. Hence, lattice …

When intense light interacts with an atomic gas, recollision between an ionizing electron and
its parent ion creates high-order harmonics of the fundamental laser frequency. This sub …

Attosecond science offers formidable tools for the investigation of electronic processes at the
heart of important physical processes in atomic, molecular and solid-state physics. In the last …

Acceleration and collision of particles has been a key strategy for exploring the texture of
matter. Strong light waves can control and recollide electronic wavepackets, generating high …

Valence electrons contribute a small fraction of the total electron density of materials, but
they determine their essential chemical, electronic and optical properties. Strong laser fields …

High-harmonic generation (HHG) is an extreme nonlinear process in which intense pulses
of light drive matter to emit high harmonics of the driving frequency, reaching the extreme …
