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 …

Optical bound states in the continuum (BICs) underpin the existence of strongly localized
waves embedded into the radiation spectrum. Here we bring the concept of BICs to the field …

X-ray free-electron lasers (XFELs) and table-top sources of x-rays based upon high
harmonic generation (HHG) have revolutionized the field of ultrafast x-ray atomic and …

Attosecond light pulses in the extreme ultraviolet have drawn a great deal of attention due to
their ability to interrogate electronic dynamics in real time. Nevertheless, to follow charge …

We demonstrate, to our knowledge, the first bright circularly polarized high-harmonic beams
in the soft X-ray region of the electromagnetic spectrum, and use them to implement X-ray …

Laser-driven high-harmonic generation provides the only demonstrated route to generating
stable, tabletop attosecond x-ray pulses but has low flux compared to other x-ray …

Attosecond science opened the door to observing nuclear and electronic dynamics in real
time and has begun to expand beyond its traditional grounds. Among several spectroscopic …

Attosecond science has paved the way for direct probing of electron dynamics in gases and
solids. This review provides an overview of recent attosecond measurements, focusing on …

High-harmonic generation is a universal response of matter to strong femtosecond laser
fields, coherently upconverting light to much shorter wavelengths. Optimizing the conversion …
