Magnetothermal instabilities in magnetized anisotropic plasmas
(2012-07-13)
Using the 16-moment transport equations for an ideal anisotropic collisionless plasma we analyze the influence of pressure anisotropy on the magnetothermal (MTI) and heat-flux-driven buoyancy (HBI) instabilities. We calculate ...

Anisotropy and nonuniversality in scaling laws of the large-scale energy spectrum in rotating turbulence
(American Physical Society, 2012-09)
Rapidly rotating turbulent flow is characterized by the emergence of columnar structures that are representative of quasi-two-dimensional behavior of the flow. It is known that when energy is injected into the fluid at an ...
Magnetic phases at the molecular scale: the case of cylindrical Co nanoparticles
(Springer, 2017-05-25)
The magnetic phases of cobalt nanocylinders at the molecular scale have been studied by means of density functional theory together with micromagnetism. Diameters of the objects are under 1 nm. The magnetic phases resulting ...
Turbulence in collisionless plasmas: statistical analysis from numerical simulations with pressure anisotropy
(IOP PUBLISHING LTD, 2011)
In recent years, we have experienced increasing interest in the understanding of the physical properties of collisionless plasmas, mostly because of the large number of astrophysical environments (e. g. the intracluster ...
Large-scale anisotropy in stably stratified rotating flows
(American Physical Society, 2014-08)
We present results from direct numerical simulations of the Boussinesq equations in the presence of rotation and/or stratification, both in the vertical direction. The runs are forced isotropically and randomly at small ...
Effects of change in slab geometry on the mantle flow and slab fabric in Southern Peru
(American Geophysical Union, 2016-10)
The effects of complex slab geometries on the surrounding mantle flow field are still poorly understood. Here we combine shear wave velocity structure with Rayleigh wave phase anisotropy to examine these effects in southern ...
Dual constant-flux energy cascades to both large scales and small scales
(American Institute of Physics, 2017-11)
In this paper, we present an overview of concepts and data concerning inverse cascades of excitation towards scales larger than the forcing scale in a variety of contexts, from two-dimensional fluids and wave turbulence ...
