(a) Evolution of energy. The solid line represents the magnetic field energy and the dots stand for the kinetic energy of the electrons. (b) Change in perpendicular and parallel temperatures. The solid and dotted lines correspond to parallel and perpendicular temperatures, respectively.
Electron distribution in momentum space at different times.
(a) Time evolution of the mode characterized by , which is the most unstable mode in the linear regime. (b) Comparison of the linear growth rate between the simulation result and numerical calculation.
Electron distribution in the space at different times.
(a) Magnetic field variation in time. (b) Power spectrum associated with .
Long-time evolution of magnetic field energy (dash-dotted line) and electrostatic field energy (solid line) in logarithmic vertical scale. The electron kinetic energy is plotted as a dashed line, which, owing to the logarithmic scale, appears almost constant.
The same as Fig. 5 except that the time scale is over the entire course of the simulation, namely, .
Spatial structure associated with field (left-hand panel) and the time evolution of spectrum associated with field (right-hand panel).
