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 …

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 …

Electron–positron pair plasmas represent a unique state of matter, whereby there exists an
intrinsic and complete symmetry between negatively charged (matter) and positively …

Since the invention of chirped pulse amplification, which was recognized by a Nobel Prize in
physics in 2018, there has been a continuing increase in available laser intensity. Combined …

Positron is an excellent probe of lattice defects in solids. A thermallized positron delocalized
in lattice can be trapped at open volume defects, eg vacancies, dislocations, grain …

Pair production can be triggered by high-intensity lasers via the Breit–Wheeler process.
However, the straightforward laser–laser colliding for copious numbers of pair creation …

Radiotherapy with very high energy electrons has been investigated for a couple of decades
as an effective approach to improve dose distribution compared to conventional photon …

The ability to create matter from light is amongst the most striking predictions of quantum
electrodynamics. Experimental signatures of this have been reported in the scattering of …

Generation of energetic electron-positron pairs using multi-petawatt (PW) lasers has recently
attracted increasing interest. However, some previous laser-driven positron beams have …

Creation of electrons and positrons from light alone is a basic prediction of quantum
electrodynamics, but yet to be observed. Our simulations show that the required conditions …
