We report on the laser-driven generation of purely neutral, relativistic electron-positron pair plasmas. The overall charge neutrality, high average Lorentz factor ($\gamma_{e/p} \approx 15$), small divergence ($\theta_{e/p} \approx 10 - 20$ mrad), and high density ($n_{e/p}\simeq 10^{15}$cm$^{-3}$) of these plasmas open the pathway for the experimental study of the dynamics of this exotic state of matter, in regimes that are of relevance to electron-positron astrophysical plasmas.

We present a Monte Carlo implementation of the Bremsstrahlung, Bethe-Heitler and Coulomb Trident processes into the particle-in-cell (PIC) simulation framework. In order to address photon and

Compton-driven beam formation and magnetization via plasma microinstabilities

Compton scattering of gamma rays propagating in a pair plasma can drive the formation of a relativistic electron positron beam. This process is scrutinized theoretically and numerically via

Theory of the formation of a collisionless Weibel shock: pair vs. electron/proton plasmas

Collisionless shocks are shocks in which the mean-free path is much larger than the shock front. They are ubiquitous in astrophysics and the object of much current attention as they are known to be

Spatial-temporal evolution of the current filamentation instability

The spatial-temporal evolution of the purely transverse current filamentation instability is analyzed by deriving a single partial differential equation for the instability and obtaining the

The microphysics of collisionless shock waves

This review adresses the physics of shock formation, shock dynamics and particle acceleration based on a close examination of available multi-wavelength or in situ observations, analytical and numerical developments and focuses on the different instabilities triggered during the shock formation and in association with particle acceleration processes.



Plans for the creation and studies of electron–positron plasmas in a stellarator

Electron–positron plasmas are unique in their behavior due to the mass symmetry. Strongly magnetized electron–positron, or pair, plasmas are present in a number of astrophysical settings, such as

Creation and uses of positron plasmas

Advances in positron trapping techniques have led to room‐temperature plasmas of 107 positrons with lifetimes of 103 s. Improvements in plasma manipulation and diagnostic methods make possible a

Table-top laser-based source of femtosecond, collimated, ultrarelativistic positron beams.

The generation of ultrarelativistic positron beams with short duration, small divergence, and high density from a fully optical setup is reported, and the detected positron beam propagates with high-density electron beam and γ rays, thus closely resembling the structure of an astrophysical leptonic jet.

Laser-driven generation of collimated ultra-relativistic positron beams

We report on recent experimental results concerning the generation of collimated (divergence of the order of a few mrad) ultra-relativistic positron beams using a fully optical system. The positron
