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 …

Optical elements that convert the spin angular momentum (SAM) of light into vortex beams
have found applications in classical and quantum optics. These elements—SAM-to–orbital …

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 …

Ultrafast processes in matter, such as the electron emission after light absorption, can now
be studied using ultrashort light pulses of attosecond duration (10− 18 seconds) in the …

Chiral light-matter interactions have been investigated for two centuries, leading to the
discovery of many chiroptical processes used for discrimination of enantiomers. Whereas …

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 …

Electronic dynamics in liquids are of fundamental importance, but time-resolved experiments
have so far remained limited to the femtosecond time scale. We report the extension of …

Although the time-dependent buildup of asymmetric Fano line shapes in absorption spectra
has been of great theoretical interest in the past decade, experimental verification of the …

Electron correlation and multielectron effects are fundamental interactions that govern many
physical and chemical processes in atomic, molecular and solid state systems. The process …
