We present a novel framework for finite element particle-in-cell methods based on the
discretization of the underlying Hamiltonian structure of the Vlasov–Maxwell system. We …

In this concise review of the recent developments in relativistic shock theory in the Universe
we restrict ourselves to shocks that do not exhibit quantum effects. On the other hand …

An analytical description of the interaction of laser light with a foil, described as a thin slab of
overdense plasma, is presented together with the results of multidimensional particle in cell …

The interest in relativistic beam-plasma instabilities has been greatly rejuvenated over the
past two decades by novel concepts in laboratory and space plasmas. Recent advances in …

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 …

Many competing linear instabilities are likely to occur in astrophysical settings, and it is
important to assess which one grows faster for a given situation. An analytical model …

Filamented transport of laser-generated relativistic electron beams in a plasma is studied
with reference to fast ignition of fusion targets. The study is based on transverse two …

We investigate the linear stability of the system formed by an electron beam and its return
plasma current within a general framework, namely, for any orientation of the wave vector k …

The paper is devoted to the prospects of using the laser radiation interaction with plasmas in
the laboratory relativistic astrophysics context. We discuss the dimensionless parameters …

We investigate the nonlinear saturation of the Weibel instability in an initially unmagnetized
plasma in which two electron streams propagate in opposite directions. We then estimate …
