First numerical evidence of global Arnold diffusion in quasi--integrable systems
Massimiliano Guzzo, Elena Lega, Claude Froeschle'
We provide numerical evidence of global diffusion occurring in slightly perturbed integrable Hamiltonian systems and symplectic maps. We show that even if a system is sufficiently…
Multifractal concentrations of inertial particles in smooth random flows
Jeremie Bec
Collisionless suspensions of inertial particles (finite-size impurities) are studied in 2D and 3D spatially smooth flows. Tools borrowed from the study of random dynamical systems…
Multifractality of the Feigenbaum attractor and fractional derivatives
U. Frisch, K. Khanin, T. Matsumoto
It is shown that fractional derivatives of the (integrated) invariant measure of the Feigenbaum map at the onset of chaos have power-law tails in their cumulative distributions, wh…
The decay of homogeneous anisotropic turbulence
L. Biferale, G. Boffetta, A. Celani +3
We present the results of a numerical investigation of three-dimensional decaying turbulence with statistically homogeneous and anisotropic initial conditions. We show that at larg…
Forced Burgers Equation in an Unbounded Domain
J. Bec, K. Khanin
The inviscid Burgers equation with random and spatially smooth forcing is considered in the limit when the size of the system tends to infinity. For the one-dimensional problem, it…
