Magnetoelectric Ponderomotive Force
نویسندگان
چکیده
The dynamics of a system consisting of a matter continuum with a weak linear magnetoelectric coupling interacting with electromagnetic fields is examined on a local scale in a nonrelativistic limit. A consistent expression for the internal energy of the system is derived. The internal energy density and the continuity equation for the momentum lead to the derivation of ponderomotive forces. A nonuniform magnetoelectric coupling generates a “magnetoelectric” ponderomotive force that could be distinguished from the purely electric or magnetic ponderomotive forces by applying alternating electric and magnetic fields at distinct frequencies.

Ju l 1 99 8 Comment on ” Ponderomotive force due to neutrinos ”
The derivation of the ponderomotive force due to neutrinos by Hardy and Melrose [Phys.Rev.D 54, 6491 (1996)] is based on a flawed analysis of the ponderomotive force concept. Their conclusions also contain an erroneous physical assumption related to the neutrino emission in supernovae. A correct analysis shows the importance of the ponderomotive force due to neutrinos in type II supernovae expl...
متن کاملRelativistic ponderomotive force, Uphill acceleration, and transition to chaos.
Starting from a covariant cycle-averaged Lagrangian the relativistic oscillation center equation of motion of a point charge is deduced and analytical formulae for the ponderomotive force in a travelling wave of arbitrary strength are presented. It is further shown that the ponderomotive forces for transverse and longitudinal waves are different; in the latter, uphill acceleration can occur. In...
متن کاملFully relativistic theory of the ponderomotive force in an ultraintense standing wave.
A relativistic field-gradient (ponderomotive) force in a laser standing wave ceases to exist in a familiar form; e.g., the adiabatic Hamiltonian is not separable into kinetic and potential energies for electrons moving in the antinode planes. We show that the force in the direction across the initial motion of an electron reverses its sign and makes the high-field areas attractive for electrons...
متن کاملNon Linear Effects Produced by Electrostatic Waves in a Magnetized Plasma
Some non-linear phenomena, like ponderomotive effects and parametric decays, produced by high power electrostatic waves in a magnetized low density plasma, have been investigated experimentally. The injection of high power electrostatic waves into a plasma causes ponderomotive forces arise. Their action primarily gives rise to a plasma density depletion in front of the launching system and subs...
