The plasma approximation: The plasma approximation applies when the plasma parameter Λ, [26] representing the number of charge carriers within the Debye sphere is much higher than unity. [ 19 ] [ 20 ] It can be readily shown that this criterion is equivalent to smallness of the ratio of the plasma electrostatic and thermal energy densities.
In plasma physics, waves in plasmas are an interconnected set of particles and fields which propagate in a periodically repeating fashion. A plasma is a quasineutral , electrically conductive fluid .
In physics a non-neutral plasma is a plasma whose net charge creates an electric field large enough to play an important or even dominant role in the plasma dynamics. [1] The simplest non-neutral plasmas are plasmas consisting of a single charge species.
Plasma is the fourth state of matter. Atoms and normal matter have a nucleus with orbiting electrons. In plasma, the atoms have been torn apart and the electrons ripped away.
In physics, a plasmon is a quantum of plasma oscillation.Just as light (an optical oscillation) consists of photons, the plasma oscillation consists of plasmons.The plasmon can be considered as a quasiparticle since it arises from the quantization of plasma oscillations, just like phonons are quantizations of mechanical vibrations.
The plasma collisionality is defined as [4] [5] =, where denotes the electron-ion collision frequency, is the major radius of the plasma, is the inverse aspect-ratio, and is the safety factor. The plasma parameters m i {\displaystyle m_{\mathrm {i} }} and T i {\displaystyle T_{\mathrm {i} }} denote, respectively, the mass and temperature of the ...

In plasma physics, plasma stability concerns the stability properties of a plasma in equilibrium and its behavior under small perturbations. The stability of the system determines if the perturbations will grow, oscillate , or be damped out .
