Lattice Boltzmann model for resistive relativistic magnetohydrodynamics.
In this paper, we develop a lattice Boltzmann model for relativistic magnetohydrodynamics (MHD). Even though the model is derived for resistive MHD, it is shown that it is numerically robust even in the high conductivity (ideal MHD) limit. In order to validate the numerical method, test simulations are carried out for both ideal and resistive limits, namely the propagation of Alfvén waves in th...
متن کاملThermal effects on the propagation of large-amplitude electromagnetic waves in magnetized relativistic electron-positron plasma.
The propagation of circularly polarized electromagnetic waves along a constant background magnetic field in an electron-positron plasma is calculated by means of both a fluid and a kinetic theory treatment. In the fluid theory, relativistic effects are included in the particle motion, the wave field, and in the thermal motion by means of a function f, which depends only on the plasma temperatur...
متن کاملLinear wave propagation in relativistic magnetohydrodynamics
The properties of linear Alfvén, slow, and fast magnetoacoustic waves for uniform plasmas in relativistic magnetohydrodynamics (MHD) are discussed, augmenting the well-known expressions for their phase speeds with knowledge on the group speed. A 3 + 1 formalism is purposely adopted to make direct comparison with the Newtonian MHD limits easier and to stress the graphical representation of their...
متن کاملDispersion relations for Bernstein waves in a relativistic pair plasma.
A fully relativistic treatment of Bernstein waves in an electron-positron pair plasma has remained too formidable a task, owing to the very complex nature of the problem. In this paper, we perform contour integration of the dielectric-response function and numerically compute the dispersion curves for a uniform magnetized relativistic electron-positron pair plasma. The behavior of the dispersio...
متن کاملA relativistic beam-plasma system with electromagnetic waves
A nonlinear multiwave model that describes the interaction of an electron beam, plasma waves, and electromagnetic waves in a cold plasma is derived and studied. The derivation, which is based on slow amplitude and phase change approximations, begins with the electromagnetic Lagrangian coupled to an electron beam, a background plasma, and electrostatic and electromagnetic waves. The model obtain...
