  Reconnection and turbulence are two of the most commonly observed dynamical
processes in plasmas, but their relationship is still not fully understood.
Using 2.5D kinetic particle-in-cell simulations of both strong turbulence and
reconnection, we compare the cross-scale transfer of energy in the two systems
by analyzing the generalization of the von K\'arm\'an Howarth equations for
Hall magnetohydrodynamics, a formulation that subsumes the third-order law for
steady cascade rates. Even though the large scale features are quite different,
the finding is that the decomposition of the energy transfer is structurally
very similar in the two cases. In the reconnection case, the time evolution of
the energy transfer also exhibits a correlation with the reconnection rate.
These results provide explicit evidence that reconnection itself is
fundamentally an energy cascade process.
