The intermittency analysis of single event data (particle moments) in multiparticle production is improved, taking into account corrections due to the reconstruction of history of a particle cascade. This approach is tested within the framework of the α-model. ∗e-mail: [email protected], [email protected]

A ug 2 00 9 Intermittency on catalysts : voter model

In this paper we study intermittency for the parabolic Anderson equation ∂u/∂t = κ∆u + γξu with u : Z d × [0, ∞) → R, where κ ∈ [0, ∞) is the diffusion constant, ∆ is the discrete Laplacian, γ ∈ (0, ∞) is the coupling constant, and ξ : Z d × [0, ∞) → R is a space-time random medium. The solution of this equation describes the evolution of a " reactant " u under the influence of a " catalyst " ξ...

M ay 2 00 5 Transverse velocities , intermittency and asymmetry in fully developed turbulence

Self-similar properties of turbulence, suggested by Kolmogorov [2], have been intensively studied for a long time. The theory predicted simple scaling for the longitudinal velocity increments ur = u(x+r)−u(x), namely, 〈|ur| 〉 ∼ r. It became clear, however, that there are corrections to these scalings, usually attributed to intermittency. The only exception is the so-called 4/5thKolmogorov law [...

Spatial intermittency in decaying kinetic Alfvén wave turbulence is investigated to determine if it produces non Gaussian density fluctuations in the in-terstellar medium. Non Gaussian density fluctuations have been inferred from pulsar scintillation scaling. Kinetic Alfvén wave turbulence characterizes density evolution in magnetic turbulence at scales near the ion gyroradius. It is shown that...
