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

The development of attosecond technology is one of the most significant achievements in
the field of ultrafast optics over the past decade. Since the first experimental demonstration …

The concerted motion of two or more bound electrons governs atomic and molecular, non-
equilibrium processes including chemical reactions, and hence there is much interest in …

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 …

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 …

Electron dynamics induced by resonant absorption of light is of fundamental importance in
nature and has been the subject of countless studies in many scientific areas. Above the …

We present an interferometric pump-probe technique for the characterization of attosecond
electron wave packets (WPs) that uses a free WP as a reference to measure a bound WP …

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 …

In the past two decades high-harmonic generation (HHG) has become a key process in
ultrafast science due to the extremely short time structure of the underlying electron …

We present a theoretical study of the photoelectron attosecond beating due to interference of
two-photon transitions in the presence of autoionizing states. We show that, as a harmonic …
