The sub-cycle interaction of light and matter is one of the key frontiers of inquiry made
accessible by attosecond science. Here, we show that when light excites a pair of charge …

Recent developments in extreme ultraviolet (XUV) and x-ray radiation sources have pushed
pulse energies and durations to unprecedented levels that opened up the era of non-linear …

Three decades ago, a highly nonlinear nonpertubative phenomenon, now well-known as
the high harmonic generation (HHG), was discovered when intense laser irradiates gaseous …

Optical-field sampling techniques provide direct access to the electric field of visible and
near-infrared light. The existing methods achieve the necessary bandwidth using highly …

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 …

Controlling the polarization state of electromagnetic radiation enables the investigation of
fundamental symmetry properties of matter through chiroptical processes. Over the past …

The quantum mechanical motion of electrons and nuclei in systems spatially confined to the
molecular dimensions occurs on the sub-femtosecond to the femtosecond timescales …

Inferring physical parameters of turbulent flows by assimilation of data measurements is an
open challenge with key applications in meteorology, climate modeling, and astrophysics …

Ultrashort electron pulses are crucial for time-resolved electron diffraction and microscopy of
the fundamental light-matter interaction. In this work, we study experimentally and …

Understanding the temporal profiles of high harmonics is essential for their applications in
attosecond science,. Microscopically, the dipole phase plays an important role in …
