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 …

Since the second half of the 20th century, ideas to develop methods for the formation of
optical vortices (OVs) or OV beams–regions of circular motion of energy flow in an …

The field of attosecond nanophysics, combining the research areas of attosecond physics
with nanoscale physics, has experienced a considerable rise in recent years, both …

On the basis of real-time ab initio calculations, we study the nonperturbative interaction of
two-color laser pulses with Mg O crystal in the strong-field regime to generate isolated …

Recent developments of high harmonic generation (HHG) have enabled the production of
structured extreme-ultraviolet (EUV) ultrafast laser beams with orbital angular momentum …

Strong-field methods in solids enable new strategies for ultrafast nonlinear spectroscopy
and provide all-optical insights into the electronic properties of condensed matter in …

Linearly polarized vector beams are structured lasers whose topology is characterized by a
well-defined Poincaré index, which is a topological invariant during high-order harmonic …

Extreme ultraviolet light delivering radiation with a wavelength shorter than approximately
100 nm is now available from solid-state sources. However, despite exceptional progress …

High harmonic generation (HHG) in crystals has revealed a wealth of perspectives such as
all-optical mapping of the electronic band structure, ultrafast quantum information, and the …

High-order harmonic generation (HHG) from crystals is emerging as a new ultrashort source
