Interaction between electrostatic collisionless shocks generates strong magnetic fields

Abstract The head-on collision between electrostatic shocks is studied via multi-dimensional Particle-In-Cell simulations. A strong magnetic field develops after the interaction, which causes shock velocities to drop significantly. This transverse generated by Weibel instability, driven pressure anisotropies due longitudinal electron heating while approach each other. possibility explore physics underpinning in laboratory with current laser facilities discussed.
