# Effective attraction between oscillating electrons in a plasmoid via acoustic wave exchange

@article{Dvornikov2011EffectiveAB, title={Effective attraction between oscillating electrons in a plasmoid via acoustic wave exchange}, author={Maxim Dvornikov}, journal={Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences}, year={2011}, volume={468}, pages={415 - 428} }

We consider the effective interaction between electrons owing to the exchange of virtual acoustic waves in a low-temperature plasma. Electrons are supposed to participate in rapid radial oscillations, forming a spherically symmetric plasma structure. We show that under certain conditions, this effective interaction can result in the attraction between oscillating electrons and can be important for the dynamics of a plasmoid. Some possible applications of the obtained results to the theory of…
