Streamer-induced transport in electron temperature gradient turbulence
The question if and how streamers (i.e., radially elongated vortices) can lead to an enhancement of the electron heat transport in electron temperature gradient turbulence is addressed. To this aim, t...

By using a hydrodynamic model, Zakharov–Kuznetsov (ZK) equation for a rotating magnetoplasma consisting of weakly relativistic electrons and positrons as well as stationary positive ions is derived. The existence condition as well as the pulse-shaped localized solution of the ZK equation are obtained. Numerical analysis reveal that the profile and the phase velocity of the nonlinear pulses are significantly affected by the ion concentration, the plasma streaming speeds, as well as the positron-to-electron temperature ratio. Furthermore, the bending instability of the nonlinear excitations is investigated using the direct-k perturbation expansion method. ©2009 American Institute of Physics
