TL;DR

This paper investigates plasma stability in magnetic fields, identifying critical density thresholds for instability and exploring how chaos affects particle confinement.

Contribution

It provides new criteria for plasma instability in magnetic fields and analyzes the impact of chaotic regimes on particle confinement.

Findings

Plasma becomes unstable above a critical density.

Chaotic regimes influence particle confinement.

Abstract

The dynamics of the oscillator system is investigated. The conditions under which this dynamics becomes unstable are determined. In particular, it is shown that plasma in constant magnetic field becomes unstable if its density exceeds a certain critical value. The role of chaotic regimes on confinement of particles (oscillators) in confining potentials is studied.
