Generalized wavefront phase for non-Kolmogorov turbulence
Optics Letters, 2008 We introduce the Lévy fractional Brownian field family to model the turbulent wavefront phase. This generalized model allows us to overcome the limitations found in a previous approach [Perez et al., J. Opt. Soc. Am. A 21, 1962 (2004)]. More precisely, our new model provides stationary phase increments over the full inertial range. Thus it successfully

Invariant forms and control dimensional parameters in complexity quantification
Frontiers in Applied Mathematics and Statistics, 2023 Non-equilibrium dynamics is omnipresent in nature and technology and can exhibit symmetries and order. In idealistic systems this universality is well-captured by traditional models of dynamical systems. Realistic processes are often more complex.

A weak turbulence theory for incompressible magnetohydrodynamics [PDF]
, 2000 We derive a weak turbulence formalism for incompressible magnetohydrodynamics. Three-wave interactions lead to a system of kinetic equations for the spectral densities of energy and helicity. The kinetic equations conserve energy in all wavevector planes

Turbulence in the interstellar medium [PDF]
, 2014 Turbulence is ubiquitous in the insterstellar medium and plays a major role in several processes such as the formation of dense structures and stars, the stability of molecular clouds, the amplification of magnetic fields, and the re-acceleration and ...

Synthetic turbulence prediction in non-Kolmogorov turbulence
Journal of Physics: Conference Series, 2011 We use Kinematic Simulation to assess the role of sweeping in the theory of Richardson for particle pair dispersion. We use different spectral laws to show the particular case of Kolmogorov spectrum. KS shows good consistency with Richardson's locality assumption for a large range of spectral laws (1.15 ≤ p ≤ 1.96).

Decoherence of Higher Order Orbital Angular Momentum Entangled State in Non-Kolmogorov Turbulence
Photonics, 2022 The decay of OAM entanglement in non-Kolmogorov turbulence has been numerically evaluated. In this work, we explore the evolution of OAM entanglement with higher-order OAM mode in the weak scintillation regime. In particular, the results of the numerical

The two-dimensional Kolmogorov-Smirnov test [PDF]
, 2007 Goodness-of-fit statistics measure the compatibility of random samples against some theoretical probability distribution function. The classical one-dimensional Kolmogorov-Smirnov test is a non-parametric statistic for comparing two empirical ...

Gravity wave turbulence in a laboratory flume [PDF]
, 2007 We present an experimental study of the statistics of surface gravity wave turbulence in a flume of a horizontal size 12×6 m. For a wide range of amplitudes the wave energy spectrum was found to scale as Eω∼ω-ν in a frequency range of up to one decade ...
