Thermodynamics of driven systems via the Kuramoto-Sivashinsky equation
E. Hansen, W. Barham, P. J. Morrison
We examine the differences between the driven turbulence described by the Kuramoto-Sivashinsky (KS) equation and the second law of thermodynamics. A general velocity and entropy de…

On the Poisson brackets of hybrid plasma models with kinetic ions and massless electrons
Yingzhe Li, Philip J. Morrison, Stefan Possanner +1
We investigate the conditions under which the Jacobi identity holds for a class of recently introduced anti-symmetric brackets for the hybrid plasma models with kinetic ions and ma…

Semi-Lagrangian methods for a plasma hybrid model with multi-species kinetic ions and massless electrons
Yingzhe Li, Philip J. Morrison, Eric Sonnendrücker
The semi-Lagrangian methods with the improved number of one-dimensional advections are proposed for a plasma hybrid model with kinetic ions and mass-less electrons. Two subsystems…
