Kinetic plasma turbulence during the nonlinear stage of the Kelvin-Helmholtz instability
Koen Kemel, Pierre Henri, Giovanni Lapenta +2
Using a full kinetic, implicit particle-in-cell code, iPiC3D, we studied the properties of plasma kinetic turbulence, such as would be found at the interface between the solar wind…
Nonuniformity effects in the negative effective magnetic pressure instability
Koen Kemel, Axel Brandenburg, Nathan Kleeorin +1
Using direct numerical simulations (DNS) and mean-field simulations (MFS), the effects of non-uniformity of the magnetic field on the suppression of the turbulent pressure is inves…
Active region formation through the negative effective magnetic pressure instability
Koen Kemel, Axel Brandenburg, Nathan Kleeorin +2
The negative effective magnetic pressure instability operates on scales encompassing many turbulent eddies and is here discussed in connection with the formation of active regions…
Detection of negative effective magnetic pressure instability in turbulence simulations
Axel Brandenburg, Koen Kemel, Nathan Kleeorin +2
We present the first demonstration of the negative effective magnetic pressure instability in direct numerical simulations of stably stratified, externally forced, isothermal hydro…
A model of driven and decaying magnetic turbulence in a cylinder
Koen Kemel, Axel Brandenburg, Hantao Ji
Using mean-field theory, we compute the evolution of the magnetic field in a cylinder with outer perfectly conducting boundaries, an imposed axial magnetic and electric field. The…
Turbulent magnetic pressure instability in stratified turbulence
Koen Kemel, Axel Brandenburg, Nathan Kleeorin +1
A reduction of total mean turbulent pressure due to the presence of magnetic fields was previously shown to be a measurable effect in direct numerical simulations. However, in the…
