Abstract: Overtaking collisions of oblique isothermal ion‐acoustic multisolitons are studied in an ultra‐relativistic degenerate dense magnetoplasma, containing non‐degenerate inertial warm ions and ultra‐relativistic degenerate inertialess electrons and positrons. A non‐linear Korteweg‐de Vries (KdV) equation describing oblique… read more here.

DOI: 10.1002/ctpp.202000188
Abstract: The impact ignition model is proposed based on the collision of a deuterium‐tritium (DT) layer accelerated to high velocities in a conical target. Simple mechanism, low cost, high coupling efficiency, and lack of the need… read more here.
