Dissipation in PIC simulations of moderate to low \b{eta} plasma turbulence

Understand

We simulate decaying turbulence in electron-positron pair plasmas using a fully- kinetic particle-in-cell (PIC) code.

• We run two simulations with moderate-to-low plasma beta.
• The energy decay rate is found to be similar in both the cases.
• The perpendicular wave-number spectrum of magnetic energy shows a slope of k^-1.3 in both the cases.
