Abstract

We investigate the influence of radiation pressure on the collective dynamics of a degenerate electron--positron plasma interacting with an intense radiation flux. Assuming the Fermi energy substantially exceeds the thermal energy, we apply general covariant hydrodynamic equations to demonstrate that in a sufficiently dense plasma, radiation pressure outpaces the increase of relativistic inertia, yielding an enhanced terminal bulk Lorentz factor. Furthermore, this process is accompanied by dynamic plasma cooling.
