Query: Von Karman-Howarth equation for Hall magnetohydrodynamics: Hybrid
  simulations   A dynamical vectorial equation for homogeneous incompressible Hall-MHD
turbulence together with the exact scaling law for third-order correlation
tensors, analogous to that for the incompressible MHD, is rederived and applied
to the results of two-dimensional hybrid simulations of plasma turbulence. At
large (MHD) scales the simulations exhibits a clear inertial range where the
MHD dynamic law is valid. In the sub-ion range the cascade continues via the
Hall term but the dynamic law derived in the framework of incompressible Hall
MHD equations is obtained only in a low plasma beta simulation. For a higher
beta plasma the cascade rate decreases in the sub-ion range and the change
becomes more pronounced as the plasma beta increases. This break in the cascade
flux can be ascribed to non thermal (kinetic) features or to others terms in
the dynamical equation that are not included in the Hall-MHD incompressible
approximation.
