We address the question of whether numerical particle-in-cell (PIC) simulations and laboratory laser-plasma experiments can (or will be able to, in the near future) model realistic gamma-ray burst (GRB) shocks. For this, we compare the radiative cooling time, tcool, of relativistic electrons in the shock magnetic fields to the microscopic dynamical time of collisionless relativistic shocks — th...

We use molecular dynamics simulations to study the formation and stability of single- multicomponent lattices in outer crust neutron stars. Including an improved treatment for Gaussian charge distributions ions, we obtain expressions potential forces arising from electron screened Coulomb interactions using efficient Ewald sum procedure. Our findings show that. baryon densities crust, a pointli...

Strongly coupled plasmas are ubiquitous in nature as they are found in stars, brown dwarfs and giant planets. A study of the physical properties of such plasmas in the laboratory is therefore of great importance to our understanding of the universe. Another very important problem associated with strongly coupled plasmas is the slowing down of charged particles in such systems. It has been theor...

In a classical plasma the momentum distribution, $n(k)$, decays exponentially, for large $k$, and same is observed an ideal Fermi gas. However, when quantum correlation effects are relevant simultaneously, algebraic decay, $n_\infty(k)\sim k^{-8}$ has been predicted. This of relevance cross sections threshold processes in dense plasmas that depend on number energetic particles. Here we present ...
