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 …

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

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 …

The dynamics of quantum systems are encoded in the amplitude and phase of wave
packets. However, the rapidity of electron dynamics on the attosecond scale has precluded …

Photoemission of an electron is commonly treated as a one-particle phenomenon. With
attosecond streaking spectroscopy we observe the breakdown of this single active-electron …

Attosecond metrology of atoms has accessed the time scale of the most fundamental
processes in quantum mechanics. Transferring the time-resolved photoelectric effect from …

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

The interaction of an extreme-ultraviolet attosecond pulse with a molecular system suddenly
removes electrons, which can lead to significant changes in the chemical bonding and …

The availability of attosecond-duration extreme ultraviolet or soft X-ray light sources has
opened up new fields of research in atomic and molecular physics. These pulses can be as …

Time delays of electrons emitted from an isotropic initial state with the absorption of a single
photon and leaving behind an isotropic ion are angle independent. Using an interferometric …
