Kappa Distributions and Turbulence: Theory and Applications in space plasmas

Session ID#: 81350

Session Description:
Classical collisional particle systems residing in thermal equilibrium have their particle velocities stabilized into a Maxwellian distribution; on the contrary, space plasmas are typically collisionless particle systems residing in stationary states characterized by kappa distributions. A breakthrough came with the connection of these distributions with the framework of statistical mechanics and thermodynamics. Turbulence, on the other hand, describes the nonlinear dynamics of the magnetic and kinetic fluctuations in space plasmas. Kappa distributions and turbulence affect the dynamics and complexity of similar plasma processes, e.g., particle acceleration, transport theory, plasma heating, plasma waves and instabilities, cosmic rays spectra. Kappa distributions and turbulence have both become increasingly widespread across the physics of space plasma processes and appear in numerous solar, heliospheric, and magnetospheric physics applications. We welcome contributions based on observations and theoretical developments related with the framework of kappa distributions and/or turbulence.
