Abstract: We study how the presence of a background magnetic field, of intensity compatible with current observation constraints, affects the linear evolution of cosmological density perturbations at ...
Anisotropic Inverse Cascade toward Zonal Flow in Magnetically Confined Plasmas
Magnetically Confined Plasmas Anisotropic Inverse Cascade toward Zonal Flow
2011/9/1
We propose a new mechanism for the generation of zonal flows in magnetically confined plasmas,complementing previous theories based on a modulational instability. We derive a new conservation law that...
