| Zusammenfassung |
The nonextensive statistics formalism proposed by Tsallis has found many applications in systems with
memory effects, long range spatial correlations, and in
general whenever the phase space has fractal or multi-fractal
structure. These features may appear naturally in turbulent or
non-neutral plasmas. In fact, the equilibrium distribution functions which
maximize the nonextensive entropy strongly resemble the non-Maxwellian particle
distribution functions observed in space and laboratory
and turbulent pure electron plasmas.
In this article we apply the Tsallis entropy formalism to the
problem of longitudinal oscillations in a proton-electron plasma. In
particular, we study the equilibrium distribution function and the
dispersion relation of longitudinal oscillations in a relativistic
plasma, finding interesting differences with the nonrelativistic
treatment. |
