# Generalized entropy production in collisionless plasma flows and turbulence

@inproceedings{Zhdankin2021GeneralizedEP, title={Generalized entropy production in collisionless plasma flows and turbulence}, author={Vladimir Zhdankin}, year={2021} }

Collisionless plasmas exhibit nonthermal and anisotropic particle distributions after being energized; as a consequence, they enter a low-entropy state relative to the thermal state. The Vlasov equations predict that in a collisionless plasma with closed boundaries, entropy is formally conserved, along with an infinite set of other Casimir invariants; this provides a seemingly strong constraint that may explain how plasmas maintain low entropy. Nevertheless, entropy is commonly believed to be…

A plasma whose Coulomb-collision rate is very small may relax on a shorter time scale to non-Maxwellian quasi-equilibria, which, nevertheless, have a universal form, with dependence on initial…

The results are important because they identify what is probably a universal Kolmogorov-like regime for kinetic turbulence; and because any physical process that produces fluctuations of the gyrophase-independent part of the distribution function may, via the entropy cascade, result in turbulent heating at a rate that increases with the fluctuation amplitude, but is independent of the collision frequency.
