This report presents the conceptual design of a new European research infrastructure
EuPRAXIA. The concept has been established over the last four years in a unique …

Relativistic flying mirrors in plasmas are thin, dense electron or electron–ion layers
accelerated by high-intensity electromagnetic waves to velocities close to the speed of light …

J-KAREN-P is a high-power laser facility aiming at the highest beam quality and irradiance
for performing state-of-the art experiments at the frontier of modern science. Here we …

The ways toward modeling of astrophysical processes and extreme field regimes with super-
power lasers are discussed. The main attention is paid to the problem of limited similarity in …

The continuous trend towards higher and higher laser intensities has opened the way to
new physical regimes and advanced applications of laser-plasma interactions, thus …

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 …

A high-contrast high-intensity petawatt-class Ti: sapphire chirped-pulse amplification laser
has been developed for research on high field science. A saturable absorber and a low-gain …

When the parameters of electron-extreme power laser interaction enter the regime of
dominated radiation reaction, the electron dynamics changes qualitatively. The adequate …

The question of whether Hawking evaporation violates unitarity, and therefore results in the
loss of information, has remained unresolved since Hawking's seminal discovery. To date …

The quantum vacuum plays a central role in physics. Quantum electrodynamics (QED)
predicts that the properties of the fermionic quantum vacuum can be probed by extremely …
