Diagram of the global energy balance between large and sub-ion scales in our simulation. The superscripts < and > indicate quantities at scales k d_i < 1.5 and k d_i ≥ 1.5 respectively. The arrows indicate the direction in which the energy is transferred by the corresponding channels (the double arrows indicate no preferred direction). Solid arrows indicate strong channels while weak channels are represented by dashed arrows. The two colors used for indicate (orange) and (purple).
