We study a quantum spherically symmetric object which is based on radial plasma oscillations. Such a plasmoid is supposed to exist in a dense plasma containing electrons, ions, and neutral particles. The method of creation and annihilation operators is applied to quantize the motion of charged particles in a self-consistent potential. We also study the effective interaction between oscillating particles owing to the exchange of a virtual acoustic wave, which is excited in the neutral component of plasma. It is shown that this interaction can be attractive and result in the formation of ion pairs. We discuss possible applications of this phenomenon in astrophysical and terrestrial plasmas.

“…There is, however, another possibility for charged particles of equal polarities to experience an effective attraction in a plasma. It happens when charged particles interact via an acoustic wave appearing in the neutral component of plasma (Vlasov & Yakovlev, 1978). This process is analogous to the phonon exchange be-tween two electrons in metal (Madelung, 1978).…”

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 natural long-lived plasma structures are also discussed.

“…Such natural plasma structures probably have an electromagnetic origin. However, as was asserted in [6], the application of classical electrodynamics to describe such plasma objects runs up against insurmountable difficulties.…”
