Variational principle and stationary mirror structures in a plasma with pressure anysotropy
Date/Time: 16:30 08-Aug-2014
Based on Grad?Shafranovlike equations, a gyrotropic plasma where the pressures in the static regime are
only functions of the amplitude of the local magnetic field is shown to be amenable to a variational principle
with a free energy density given by the parallel tension. This approach is used to demonstrate that small
amplitude static holes constructed slightly below the mirror instability threshold identify with lump solitons
of KPII (Kadomtsev?Petviashvili) equation and turn out to be unstable. It is also shown that regularizing
effects such as finite Larmor radius corrections cannot be ignored in the description of largeamplitude mir
ror structures.
