Temperature anisotropy instabilities driven by intermittent velocity shears in the solar wind
Sorriso-Valvo, Luca; Verscharen, Daniel; Chen, Christopher H. K. +5 more
Where and under what conditions the transfer of energy between electromagnetic fields and particles takes place in the solar wind remains an open question. We investigate the conditions that promote the growth of kinetic instabilities predicted by linear theory to infer how turbulence and temperature-anisotropy-driven instabilities are interrelate…
Efficient kinetic Lattice Boltzmann simulation of three-dimensional Hall-MHD turbulence
Telloni, Daniele; Marino, Raffaele; Foldes, Raffaello +4 more
Simulating plasmas in the Hall-magnetohydrodynamics (Hall-MHD) regime represents a valuable approach for the investigation of complex nonlinear dynamics developing in astrophysical frameworks and fusion machines. The Hall electric field is computationally very challenging as it involves the integration of an additional term, proportional to \nabla…
