Global and Local: Synchronization and Emergence
Mogens H. Jensen, Leo P. Kadanoff
When a dynamical system contains several different modes of oscillations it may behave in a variety of ways: If the modes oscillate at their own individual frequencies, it exhibits…
On two-dimensionalization of three-dimensional turbulence in shell models
Sagar Chakraborty, Mogens H. Jensen, Amartya Sarkar
Applying a modified version of the Gledzer-Ohkitani-Yamada (GOY) shell model, the signatures of so-called two-dimensionalization effect of three-dimensional incompressible, homogen…
Kolmogorov scaling from random force fields
Mogens H. Jensen, Kim Sneppen, Luiza Angheluta
We show that the classical Kolmogorov and Richardson scaling laws in fully developed turbulence are consistent with a random Gaussian force field. Numerical simulations of a shell…
Exact Periodic Solutions of Shells Models of Turbulence
Poul Olesen, Mogens H. Jensen
We derive exact analytical solutions of the GOY shell model of turbulence. In the absence of forcing and viscosity we obtain closed form solutions in terms of Jacobi elliptic funct…
Weak noise approach to the logistic map
Hans C. Fogedby, Mogens H. Jensen
Using a nonperturbative weak noise approach we investigate the interference of noise and chaos in simple 1D maps. We replace the noise-driven 1D map by an area-preserving 2D map mo…
Dual Multifractal Spectra
Stephane Roux, Mogens H. Jensen
The multifractal formalism characterizes the scaling properties of a physical density rho as a function of the distance L. To each singularity alpha of the field is attributed a fr…
A Critical "Dimension" in a Shell Model for Turbulence
Paolo Giuliani, Mogens H. Jensen, Victor Yakhot
We investigate the GOY shell model within the scenario of a critical dimension in fully developed turbulence. By changing the conserved quantities, one can continuously vary an ``e…
