Flame front propagation VI: Dynamics and Wrinkling of Radially Propagating Fronts Inferred from Scaling Laws in Channel Geometries
Barak Galanti, Oleg Kupervasser, Zeev Olami +1
Flame Propagation is used as a prototypical example of expanding fronts that wrinkle without limit in radial geometries but reach a simple shape in channel geometry. We show that t…
Flame front propagation III: Random Noise and Pole-Dynamics in Unstable Front Propagation (new version)
Oleg Kupervasser, Zeev Olami, Barak Galanti +1
The problem of flame propagation is studied as an example of unstable fronts that wrinkle on many scales. The analytic tool of pole expansion in the complex plane is employed to ad…
Extended and localized vibrations models in disordered systems
Barak Galanti, Zeev Olami
We discuss vibrational localization problems in glasses and disordered media in this paper. It is claimed that the essence of the localization problem is already observed in disord…
Extended and localized phonons, free electrons, and diffusive states in disordered lattice models
Barak Galanti, Zeev Olami
In this paper we propose that phonons, free diffusive electrons, and diffusion in two-and three--dimensional disordered lattice problems belong to a different class of localization…
Direct Numerical Simulations of the Kraichnan Model: Scaling Exponents and Fusion Rules
Adrienne L. Fairhall, Barak Galanti, Victor S. L'vov +1
We present results from direct numerical simulations of the Kraichnan model for passive scalar advection by a rapidly-varying random scaling velocity field for intermediate values…

Zeev Olami, Barak Galanti, Oleg Kupervasser +1
The problem of flame propagation is studied as an example of unstable fronts that wrinkle on many scales is studied. The analytic tool of pole expansion in the complex plane is eml…
