Hydrodynamic Lyapunov Modes in Translation Invariant Systems
Jean-Pierre Eckmann, Omri Gat
We study the implications of translation invariance on the tangent dynamics of extended dynamical systems, within a random matrix approximation. In a model system, we show the exis…
Perturbative and Non-Perturbative Analysis of the 3'rd Order Zero Modes
Omri Gat, Victor S. L'vov, Itamar Procaccia
The anomalous scaling behavior of the n-th order correlation functions of the Kraichnan model of turbulent passive scalar advection is believed to be dominated by the homogen…
Non-Perturbative Zero Modes in the Kraichnan Model for Turbulent Advection
Omri Gat, Victor S. L'vov, Evgenii Podivilov +1
The anomalous scaling behavior of the n-th order correlation functions of the Kraichnan model of turbulent passive scalar advection is believed to be dominated by the…
The Breakdown of Dynamic Scaling and Intermittency in a Cascade Model of Turbulence
Omri Gat, Itamar Procaccia, Reuven Zeitak
We present an analytic and numerical analysis of the Gledzer-Ohkitani-Yamada (GOY) cascade model for turbulence. We concentrate on the dynamic correlations, and demonstrate both nu…
