The dynamics of charged particles in electromagnetic fields is an essential component of
understanding the most extreme environments in our Universe. In electromagnetic fields of …

Ultrashort pulsed lasers provide uniquely detailed access to the ultrafast dynamics of
physical, chemical, and biological systems, but only a handful of wavelengths are directly …

Near-critical plasmas irradiated at ultra-high laser intensities (I> 1018W/cm2) allow to
improve the performances of laser-driven particle and radiation sources and to explore …

The interaction of ultra-intense laser pulses with matter opened the way to generate the
shortest light pulses available nowadays in the attosecond regime. Ionized solid surfaces …

The validation of a theory is commonly based on appealing to clearly distinguishable and
describable features in properly reduced experimental data, while the use of ab-initio …

We report evidence for the first generation of XUV spectra from relativistic surface high-
harmonic generation (SHHG) on plasma mirrors at a kilohertz repetition rate, emitted …

The availability of ever stronger, laser-generated electromagnetic fields underpins
continuing progress in the study and application of nonlinear phenomena in basic physical …

A new generation mechanism of coherent extreme-ultraviolet (XUV) and x-ray radiation
presents in the few-cycle laser interaction with solid density plasma. Two-dimensional …

Spectral modulation of high-order harmonics generated in relativistic laser-solid interaction
is investigated. Numerical simulations show that the modulation depends on surface plasma …

We present an exactly solvable example of coherent quantum interference effects in the
creation of electron-positron pairs from the collision of a photon with ultrashort laser pulses …
