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…

Collisionless relaxation of a Lynden-Bell plasma
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

Cascades and Dissipative Anomalies in Nearly Collisionless Plasma Turbulence
We develop first-principles theory of kinetic plasma turbulence governed by the Vlasov-Maxwell-Landau equations in the limit of vanishing collision rates. Following an exact renormalization-group
Fluidization of collisionless plasma turbulence
TLDR
Kolmogorov wins the competition with Landau for the free energy in a collisionless turbulent plasma, and the universality of “fluid” turbulence physics is reaffirmed even for a kinetic, collisionless system.
Energy dissipation and entropy in collisionless plasma.
TLDR
The energization and heating of collisionless plasma is investigated and the role of heat flux in the dissipation process is emphasized, in terms of fluid entropy in both isotropic and gyrotropic forms.
Phase mixing versus nonlinear advection in drift-kinetic plasma turbulence
A scaling theory of long-wavelength electrostatic turbulence in a magnetised, weakly collisional plasma (e.g. drift-wave turbulence driven by ion temperature gradients) is proposed, with account
Nonlinear phase mixing and phase-space cascade of entropy in gyrokinetic plasma turbulence.
TLDR
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.

TLDR
The simulations indicate that turbulence can be a viable source of energetic particles in high-energy astrophysical systems, such as pulsar wind nebulae, if scalings asymptotically become insensitive to the system size.
