The most-studied classes of exact solutions to Vlasov–Maxwell equations for stationary
neutral current structures in a collisionless relativistic plasma, which allow the particle …

We report experimental evidence that multi-MeV protons accelerated in relativistic laser-
plasma interactions are modulated by strong filamentary electromagnetic fields. Modulations …

Electromagnetic turbulence and ion kinetics in counterstreaming plasmas hold great
significance in laboratory astrophysics, such as turbulence field amplification and particle …

We present the first local, quantitative measurements of ion current filamentation and
magnetic field amplification in interpenetrating plasmas, characterizing the dynamics of the …

The current filamentation instability is a key phenomenon underpinning various processes in
astrophysics, laboratory laser-plasma, and beam-plasma experiments. Here we show that …

Magnetic field amplification by relativistic streaming plasma instabilities is central to a wide
variety of high-energy astrophysical environments as well as to laboratory scenarios …

Collisionless shocks are ubiquitous in the Universe as a consequence of supersonic plasma
flows swee** through interstellar and intergalactic media. These shocks are the cause of …

We study the stability of current filaments produced by the Weibel, or current filamentation,
instability in weakly magnetized counterstreaming plasmas. It is shown that a resonance …

In this first paper of a series dedicated to the microphysics of unmagnetized, relativistic
collisionless pair shocks, we discuss the physics of the Weibel-type transverse current …

The origin of the cosmic magnetic field remains an unsolved mystery, relying not only on
specific dynamo processes but also on the seed field to be amplified. Recently, the diffuse …
