Wave breaking limit in arbitrary mass ratio warm plasmas

Longitudinal wave-breaking limits in a unified geometric model of relativistic warm plasmas

The covariant Vlasov-Maxwell system is used to study breaking of relativistic warm plasma waves. The well-known theory of relativistic warm plasmas due to Katsouleas and Mori (KM) is subsumed within a unified geometric formulation of the ‘waterbag’ paradigm over spacetime. We calculate the maximum amplitude Emax of non-linear longitudinal electric waves for a particular class of waterbags whose...

Warm wave breaking of nonlinear plasma waves with arbitrary phase velocities.

A warm, relativistic fluid theory of a nonequilibrium, collisionless plasma is developed to analyze nonlinear plasma waves excited by intense drive beams. The maximum amplitude and wavelength are calculated for nonrelativistic plasma temperatures and arbitrary plasma wave phase velocities. The maximum amplitude is shown to increase in the presence of a laser field. These results set a limit to ...

Binary black hole merger in the extreme mass ratio limit

We discuss the transition from quasi-circular inspiral to plunge of a system of two nonrotating black holes of masses m1 and m2 in the extreme mass ratio limit m1m2 ≪ (m1+m2). In the spirit of the Effective One Body (EOB) approach to the general relativistic dynamics of binary systems, the dynamics of the two black hole system is represented in terms of an effective particle of mass μ ≡ m1m2/(m...

Ionization rate coefficients in warm dense plasmas.

We recast the atomic processes in a warm, dense plasma using Fermi-Dirac statistics and compare them to the rates of the usual Maxwell-Boltzmann approach of many collisional-radiative models. Population calculations show insignificant differences to calculations assuming nondegenerate free electrons of plasmas at solid density close to local thermodynamic equilibrium, but show departures in ave...
