    The use of retarded potentials to describe electromagnetic fields from source-charges is an expression of relativistic electromagnetism. Principle [ edit ] The question of how an electric field in one inertial frame of reference looks in different reference frames moving with respect to the first is crucial to understanding fields created by. This chapter contains standard preparatory material. We will present an overview of special relativity, relativistic Klein–Gordon and Dirac wave equations and the convention in this book for Dirac spinors, and a self-contained discussion of representation theory of the rotation and Lorentz groups.

    Gravitoelectromagnetism, abbreviated GEM, refers to a set of formal analogies between the equations for electromagnetism and relativistic gravitation; specifically: between Maxwell's field equations and an approximation, valid under certain conditions, to the Einstein field equations for general relativity. Gravitomagnetism is a widely used term referring specifically to the kinetic effects of. energy of the electromagnetic field, radiation and scatteri ng phenomena, electro-magnetic waves and their propagation in vacuum and in media, and covariant Lagrangian/Hamiltonian field theoretical methods for electromagnetic fields, par-ticles and interactions. The aim has been to write a book that can serve both as.

    generalized to study (relativistic) electromagnetic wave interaction with the relativistic quantum mechanical plasma and other properties of such plasma by including Maxwell equations in the system. The Klein-Gordon equation coupled to the electromagnetic scalar and vector potentials W 22 cP mc4 = 0 (3) where W= i h @ @t + e˚(r;t) (4) and 1. The relativistic electron clouds modulate the ion beam and a secondary, spatially localized electrostatic instability grows, which saturates by forming a relativistic ion phase space hole. It accelerates electrons to ultra-relativistic speeds. (3) A simulation is also revised, in which two clouds of an electron-ion plasma collide at the speed c.

Relativistic electromagnetic waves in an electron-ion plasma by Abraham C.-L Chian, unknown edition. The equations governing the propagation of relativistic electromagnetic waves in a cold electron-ion plasma can be reduced to two equations expressing conservation of energy-momentum of the system. The two conservation constants are functions of the plasma stream velocity, the wave velocity, the wave amplitude and the electron-ion mass : Abraham C.-L.

Chian, Abraham C.-L. Chian, Charles F. Kennel. High power laser beams can drive plasma particles to relativistic energies. An accurate description of strong waves requires the inclusion of ion dynamics in the analysis.

The equations governing the propagation of relativistic electromagnetic waves in a cold electron-ion plasma can be reduced to two equations expressing conservation of energy-momentum of the system. Basic equations describing a macroscopic behaviour of ultra-relativistic plasma (T≫mc 2) are formulated in a covariant form.

Waves in an electron-positron plasma are investigated in a frame of two-fluid model equation. Dispersion relations for electrostatic wave, electromagnetic wave and Alfven wave propagating parallel to a constant magnetic field are by: Nonlinear propagation of purely stationary large amplitude electromagnetic (EM) solitary waves in a magnetized electron-positron (EP) plasma is studied using a fully relativistic two-fluid hydrodynamic model which accounts for physical regimes of both weakly relativistic (P ≪ nmc 2) and ultrarelativistic (P ≫ nmc 2) random thermal energies.

Here, P is the thermal pressure, n the number. A study of the interaction between electromagnetic waves with relativistic electron holes shows that electromagnetic waves can be both linearly and nonlinearly trapped in the electron hole, which widens further due to the relativistic mass increase and ponderomotive force in the oscillating electromagnetic.

14 hours ago  Motion and radiative transitions of an electron in a magnetic field under the influence of an external electromagnetic wave are studied for various confining conditions in semiconductor, graphene, in quantum wells, and relativistic generalization in terms of the Klein–Gordon equation are considered.

In particular, the following problems are discussed. The so-called cyclotron resonance. Recent particle-in-cell simulations of the stimulated Brillouin backscattering (SBBS) of electromagnetic radiation have shown that even at sub-relativistic intensities (I λ 2 = 10 16 Wμm 2 /cm 2) non-drifting solitary waves, “solitons” for short, are easily produced, and remain almost unchanged all along the simulation time, typically for several thousands of optical cycles.

In the case that both electron and positron gases have same temperature, there does not exist the slow mode which corresponds to the ion acoustic wave. Right and left circular polarized waves propagate with the same dispersion relation which is different from one of the non-relativistic electron-ion plasma.

In this context, we have derived the nonlinear dispersion relations of the large-amplitude electromagnetic (EM) waves, the electrostatic electron plasma waves, and the ion-acoustic waves. In an electron–ion plasma, the conditions for sustaining of relativistically intense solitary waves have been obtained.

These characteristics are illustrated for nonrelativistic field amplitude. The existence of solitary waves and their properties in relativistic electron–positron plasma have. The equations governing the propagation of relativistic electromagnetic waves in a cold electron-ion plasma can be reduced to two equations expressing conservation of energy-momentum of the system.

The two conservation constants are functions of the plasma stream velocity, the wave velocity, the wave amplitude, and the electron-ion mass ratio.

Relativistic electrons have been thought to more easily resonate with electromagnetic ion cyclotron (EMIC) waves if the total density is large. We show that for a particular EMIC mode, this dependence is weak due to the dependence of the wave frequency and wave vector on the density.

Especially, the relativistic quantum electron-ion plasma are modeled using the Klein-Gordon equation and the Dirac equation for relativistic electrons. However, different properties of these.
