For over a century since the Nobel prize winning work by Einstein (1905 Ann. Phys. 17 132),
atomic photoionization was thought to be an instantaneous process. Recent experimental …

Attosecond angular streaking, also known as the'attoclock', employs a short elliptically
polarized laser pulse to tunnel ionize an electron from an atom or a molecule and to put a …

The first hundred attoseconds of the electron dynamics during strong field tunneling
ionization are investigated. We quantify theoretically how the electron's classical trajectories …

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 …

The intermediate domain of strong-field ionization between the tunneling and multiphoton
regimes is investigated using the strong-field approximation and the imaginary-time method …

Laser-induced electron tunnelling—which triggers a broad range of ultrafast phenomena
such as the generation of attosecond light pulses, photoelectron diffraction and holography …

We demonstrate a novel attoclock, in which we add a perturbative linearly polarized light
field at 400 nm to calibrate the attoclock constructed by an intense circularly polarized field …

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

Recent attoclock experiments and theoretical studies regarding the strong-field ionization of
atoms by few-cycle infrared pulses revealed features that have attracted much attention …

An ultrafast intense laser field is one of the most important tools to observe and manipulate
electronic and nuclear dynamics with subcycle precision in highly nonlinear light–matter …
