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

In this review, we will focus on the theoretical aspects in observing and controlling the
electronic dynamics in few-electron atoms and molecules by attosecond pulses in different …

We report measurements of energy-dependent photoionization delays between the two
outermost valence shells of N 2 O and H 2 O. The combination of single-shot signal …

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

In quantum systems, coherent superpositions of electronic states evolve on ultrafast time
scales (few femtoseconds to attoseconds; 1 attosecond= 0.001 femtoseconds= 10− 18 …

We present the experimental observation of two-center interference in the ionization time
delays of Kr 2. Using attosecond electron-ion-coincidence spectroscopy, we simultaneously …

Time-delays in the photoionization of molecules are investigated. As compared to atomic
ionization, the time-delays expected from molecular ionization present a much richer …

We present a theoretical formalism for the calculation of attosecond delays in molecular
photoionization. It is shown how delays relevant to one-photon-ionization, also known as …

This review article focuses on imaging and controlling ultrafast dynamics of the hydrogen
molecule and its cation, initiated by ultrashort laser pulses. We discuss the mechanisms …

Attosecond science, born at the beginning of this century with the generation of the first
bursts of light with durations shorter than a femtosecond, has opened the way to look at …
