Query: A mixed SOC-turbulence model for nonlocal transport and space-fractional
  Fokker-Planck equation   The phenomena of nonlocal transport in magnetically confined plasma are
theoretically analyzed. A hybrid model is proposed, which brings together the
notion of inverse energy cascade, typical of drift-wave- and two-dimensional
fluid turbulence, and the ideas of avalanching behavior, associable with
self-organized critical (SOC) behavior. Using statistical arguments, it is
shown that an amplification mechanism is needed to introduce nonlocality into
dynamics. We obtain a consistent derivation of nonlocal Fokker-Planck equation
with space-fractional derivatives from a stochastic Markovian process with the
transition probabilities defined in reciprocal space.
