Plasma Turbulence

Energy dissipation and particle transport in plasma turbulence across heliophysics regimes.

Self-generated turbulence in reconnection layers

3D reconnection simulations show self-generated turbulence that seeds particle transport and acceleration.

active

We probe how turbulence generated by reconnection or large-scale drivers redistributes energy and accelerates particles by combining VPIC, hybrid, and reduced turbulence models with transport diagnostics.
