High-harmonic generation in atomic gases has been studied for decades, and has formed
the basis of attosecond science. Observation of high-order harmonics from bulk crystals was …

Advances in attosecond science have led to a wealth of important discoveries in atomic,
molecular, and solid-state physics and are progressively directing their footsteps toward …

Since the first demonstration of the generation of attosecond pulses (1 as= 10− 18 s) in the
extreme-ultraviolet spectral region, several measurement techniques have been introduced …

Strong-field laser excitation of solids can produce extremely nonlinear electronic and optical
behaviour. As recently demonstrated, this includes the generation of high harmonics …

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 …

Abstract 2D materials are emerging as ideal candidates for fundamental investigations and
new technologies due to their unique optoelectronic properties. Giant nonlinear …

Laser frequency combs are coherent light sources that emit a broad spectrum of discrete,
evenly spaced narrow lines whose absolute frequency can be measured to within the …

Harmonic generation is a general feature of driven nonlinear systems. In particular high-
order harmonic generation (HHG) in atomic gases is the basis for producing attosecond …

We study the generation of high-harmonic radiation by Bloch electrons in a model
transparent solid driven by a strong midinfrared laser field. We solve the single-electron time …

High-order harmonic generation (HHG) in gases leads to short-pulse extreme ultraviolet
(XUV) radiation that is useful in a number of applications, such as attosecond science and …
