Abstract:We study a self-organized critical system under influence of turbulent motion of the environment. The system is described by the anisotropic continuous stochastic equation proposed by Kardar [Phys. Rev. Lett. 62: 1813 (1989)]. The motion of the environment is modelled by the isotropic Kazantsev-Kraichnan "rapid-change" ensemble for an incompressible fluid: it is Gaussian with vanishing correlation time and the pair correlation function of the form ∝ δ(t − t )/k d+ξ , where k is the wave number and ξ is an arb… Show more
