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 …

Recent advances in the generation of well-characterized subfemtosecond laser pulses have
opened up unpredicted opportunities for the real-time observation of ultrafast electronic …

Recently two emerging areas of research, attosecond and nanoscale physics, have started
to come together. Attosecond physics deals with phenomena occurring when ultrashort laser …

The strong fields associated with few-cycle pulses can drive highly nonlinear phenomena,
allowing the direct control of electrons in condensed matter systems. In this context, by …

The propagation and transport of electrons in crystals is a fundamental process pertaining to
the functioning of most electronic devices. Microscopic theories describe this phenomenon …

Attosecond science is based on electron dynamics driven by a strong optical electric field
and has evolved beyond its original scope in gas-phase atomic and molecular physics to …

We theoretically investigate the generation of ultrafast currents in insulators induced by
strong few-cycle laser pulses. Ab initio simulations based on time-dependent density …

Precise knowledge of the behaviour of the phase of light in a focused beam is fundamental
to understanding and controlling laser-driven processes. More than a hundred years ago, an …

We theoretically investigate the dependence of the enhancement of optical near-fields at
nanometric tips on the shape, size, and material of the tip. We confirm the strong …

Electron microscopy and electron diffraction techniques rely on electron sources. Those
sources require strong electric fields to extract electrons from metals, either by the …
