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

Feynman's path integral approach is to sum over all possible spatiotemporal paths to
reproduce the quantum wave function and the corresponding time evolution, which has …

Quantum particles can penetrate potential barriers by tunnelling. If that barrier is rotating, the
tunnelling process is modified,. This is typical for electrons in atoms, molecules or solids …

A review is presented of the rescattering plateau in laser-induced above-threshold ionization
and its various features as they were discovered over time. Several theoretical explanations …

Strong-field photoelectron holography and laser-induced electron diffraction (LIED) are two
powerful emerging methods for probing the ultrafast dynamics of molecules. However, both …

We investigate tunneling ionization of a single active electron with a strong and short laser
pulse, circularly polarized. With the recently proposed backpropagation method, we can …

Using the recently developed Coulomb quantum orbit strong-field approximation, we
perform a systematic analysis of several features encountered in above-threshold ionization …

Imaging the microscopic world in real space and real time is a grand challenge of science. In
the landscape of time-resolved imaging techniques, laser-induced electron diffraction (LIED) …

We investigate tunneling ionization of a model helium atom in a strong circularly polarized
short laser pulse using the classical backpropagation method and compare ten different …
