Classical particle systems reside at thermal equilibrium with their velocity distribution function stabilized into a Maxwell distribution. On the contrary, collisionless and correlated particle systems, such as space and astrophysical plasmas, are characterized by a non-Maxwellian behavior, typically described by the so-called kappa distributions, or combinations thereof. Empirical kappa distributions have become increasingly widespread across space and plasma physics. A breakthrough in the field came with the connection of these distributions with the solid theory of non-extensive statistical mechanics.
Understanding the statistical origin of these distributions was a cornerstone of theoretical developments and a plethora of applications in space plasma physics and complexity science: within the vast space region of our heliosphere, from the solar wind and the planetary magnetospheres to the outer boundary region of the inner heliosheath, and beyond, to the interstellar and galactic astrophysical plasmas.
We welcome abstracts reporting on the progress of the following three broad subject areas:
- Theory of Kappa Distributions and Statistical Framework:
Nonextensive statistical mechanics; Superstatistics; Connection with thermodynamics; Entropy; Information measure; Temperature and zero-th law of thermodynamics; Anisotropy of velocity space; Distributions with potential energy.
- Applications in Space and Astrophysical Plasmas:
Solar/Stellar atmospheres; Inner/Outer Heliosphere; Solar Flares/CMEs; Solar wind; Energetic Particles; Pick-up Ions; Terrestrial, Planetary, and Cometary Magnetospheres; Inner/Outer Heliosheath; Interstellar plasmas; Nebular, galactic and intergalactic plasmas.
- Effects on Plasma Processes, Dynamics, and Complexity:
Particle acceleration; Transport and diffusion; Plasma linear/nonlinear waves and instabilities; Shocks and Rankine–Hugoniot conditions; Polytropic relations; Plasma interactions; Correlations and coupling phenomena; Turbulence; Chaos; Mechanisms generating kappa distributions.
The workshop will be held during the Sigma Phi 2023
International Conference on STATISTICAL PHYSICS (ΣΤΑΤΙΣΤΙΚΗ ΦΥΣΙΚΗ)
