The World of Atoms at the Attosecond Time Scale

Extreme Ultraviolet light sources based on high-order harmonic generation in gases consist of extremely short light bursts, in the 100-attosecond range, allowing for outstanding temporal resolution. Attosecond pulses enable the study of atoms in an entirely new way. It is now possible to measure tiny time delays in photoionization and the phase change of an electron across a resonance. Recently, the quantum state of a photoelectron has been determined by a tomography technique.
