Statistical mechanics of a two-temperature, classical plasma
Physical Review A, 1986Weakly coupled, nonequilibrium plasmas have often been described by assigning separate temperatures to the electron and ion velocity distributions. In this paper we present a model for the complete phase-space probability function which describes a two-temperature ensemble for arbitrary coupling. We discuss the ''thermodynamics'' predicted by the model,

Statistical mechanics of a spin-polarized plasma
Journal of Plasma Physics, 1988The statistical mechanics of a spin-polarized plasma is investigated in detail. A rigorous quantum-mechanical description is constructed in terms of a generalized matrix Wigner function. In order to ensure the manifest gauge invariance of the theory, the non-canonical variables q (position) and π (mechanical momentum) are used for the particles.

Statistical mechanics of magneto-active plasma
Il Nuovo Cimento B Series 11, 1972Wo have formulated the statistical mechanics of magnetoactive plasma in the framework of irreversible statistical mechanics. Starting from the formal solution of the complete Liouville equation, we have obtained the one-particle distribution function.

Statistical mechanics of a guiding centre plasma
Journal of Plasma Physics, 1977The equilibrium configurations of a one-species guiding centre plasma are circularly symmetric. Unlike results obtained for systems with artificial periodicity, the profiles depend uniquely on the energy and mean square radius. The random phase approximation is shown to be invalid.

Statistical mechanics of a weakly turbulent stable plasma
Journal of Plasma Physics, 1969The statistical mechanics of the weakly turbulent plasma is treated in an original manner by introducing the waves by means of the van Kampen modes. A system of coupled equations is derived which relates the correlations between waves and waves, waves and particles, particles and particles. The quasilinear theory is obtained at the first order, and the

Statistical mechanics of Ar2+ in an inductively coupled plasma
Spectrochimica Acta Part B: Atomic Spectroscopy, 1996Abstract In the mass spectrum of an argon inductively coupled plasma (ICP), there is a peak due to the presence of the argon dimer ion, Ar 2 + . Using elementary statistical mechanics, an attempt is made to elucidate the mechanism responsible for this ion's presence in the ICP, The assumption of local thermodynamic equilibrium (LTE) in the ICP leads

Statistical Mechanics of a Partially Ionized Hydrogen Plasma
Physical Review A, 1970A generalized Saha equation for a partially ionized hydrogen plasma is derived and used for calculating the degree of ionization and the effective ionization potential for a wide range of electron densities and temperatures. The energy eigenvalues of the hydrogen atom in a plasma are obtained as solutions of the Schr\"odinger equation from a shielded ...

Mechanical and Total Pressure Statistics in Vlasov-Maxwell Plasmas
2023Pressure is an important parameter in plasma turbulence. Historically, pressure fluctuations have been studied extensively via density in the nearly incompressible (NI) magnetohydrodynamic (MHD) framework1-3. However, the statistics of mechanical and total pressure in kinetic plasmas have not been explored much. In this study, we examine the statistics

The electrodynamics and statistical mechanics of linear plasma response functions
Journal of Statistical Physics, 1969The purpose of this paper is to review and to extend, wherever possible, the Kramers-Kronig relations, sum rules, and symmetry properties for the electrodynamic transport tensors of a linear plasma medium. For complete generality, we consider both nonrelativistic and relativistic plasmas with and without external magnetic fields.
