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 …

The debate on tunnelling times have always been full of contradictions and the attoclock
experiments that measure tunnelling delays in strong-field ionization are no exception. The …

Tunnel ionization belongs to the fundamental processes of atomic physics. The so-called
two-step model, which describes the ionization as instantaneous tunneling at the electric …

Modelling atomic processes in intense laser fields often relies on solving the time-
dependent Schrödinger equation (TDSE). For processes involving ionisation, such as above …

Ultrafast laser photoinscription of optical materials has seen a strong development in the
recent years for a range of applications in integrated photonics. Fueled by its capability to …

Modern optical physics provides means to detect and resolve ultrafast processes on a time
scale of tens of attoseconds. The physical interpretation of such measurements, however …

Quantitative identification of tunneling ionization (TI) and multiphoton ionization (MPI) with
Keldysh parameter γ in intermediate regime is of great importance to better understand …

The ideas of classical communication and holographic encoding arise in different parts of
physics. Here, we show that they are equivalent. This allows for us to reformulate the …

Electronic processes within atoms and molecules reside on the timescale of attoseconds.
Recent advances in the laser-based pump-probe interrogation techniques have made …
