Photoelectron holography constitutes a powerful tool for the ultrafast imaging of matter, as it
combines high electron currents with subfemtosecond resolution, and gives information …

The last decade has seen an intense renewed debate on tunnelling time, both from a
theoretical and an experimental perspective. Here, we review recent developments and new …

Interaction of a strong laser pulse with matter transfers not only energy but also linear
momentum of the photons. Recent experimental advances have made it possible to detect …

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 …

We present experimental data on the nonadiabatic strong field ionization of atomic hydrogen
using elliptically polarized femtosecond laser pulses at a central wavelength of 390 nm. Our …

High-intensity laser fields can ionize atoms and molecules and also initiate molecular
dissociation. This review is on the recent progress made using experiments that harness the …

We theoretically investigate the deformation of atomic p±orbitals driven by strong elliptically
polarized (EP) laser fields and the role it plays in tunnel ionization. Our study reveals that …

Canonical variables for the Poisson algebra of quantum moments are introduced here,
expressing semiclassical quantum mechanics as a canonical dynamical system that extends …

Streaking with a weak probe field is applied to ionization in a two-dimensional strong field
tailored to mimic linear polarization, but without disturbance by recollision or intracycle …

The attoclock technique which maps the emission time of a photoelectron to its detection
angle is an important tool in strong-field physics. Previously, it was implemented only with …
