Anisotropic truncation for turbulent transport and zonal flows in the Hasegawa-Wakatani system
Pierre L. Guillon, Robin Angles, Yanick Sarazin +2
Reduced models based on an anisotropic truncation of the Fourier space, retaining only a few poloidal wave-numbers while keeping the full radial resolution, are developed and first…
On the Dynamics of Bounded-Degree Automata Networks
Julio Aracena, Florian Bridoux, Maximilien Gadouleau +4
Automata networks can be seen as bare finite dynamical systems, but their growing theory has shown the importance of the underlying communication graph of such networks. This paper…
Self-organisation through layering of -plane like turbulence in plasmas and geophysical fluids
P. L. Guillon, G. Dif-Pradalier, Y. Sarazin +2
Staircase formation and layering is studied in simplified, potential vorticity conserving models of plasmas and geophysical fluids, by investigating turbulent self-organisation and…
Aperiodic monotiles: from geometry to groups
Thierry Coulbois, Anahà Gajardo, Pierre Guillon +1
In 2023, two striking, nearly simultaneous, mathematical discoveries have excited their respective communities, one by Greenfeld and Tao, the other (the Hat tile) by Smith, Myers,…
Flux-driven turbulent transport using penalisation in the Hasegawa-Wakatani system
Pierre L. Guillon, Ãzgür D. Gürcan, Guilhem Dif-Pradalier +2
First numerical results from the newly-developed pseudo-spectral code P-FLARE (Penalised FLux-driven Algorithm for REduced models) are presented. This flux-driven turbulence/transp…
Flux Jamming, Phase Transitions and Layering in Turbulent Magnetized Plasma
P. H. Diamond, Y. Kosuga, P. L. Guillon +1
This paper discusses transport barrier formation and layering as consequences of jam formation. Extensive use is made of analogies with the theory of traffic flow in one dimension.…
