Biferale L, Khomenko D, Lvov V, Pomyalov A, Procaccia I, Sahoo G
Phys Rev Lett . 2019 May; 122(14):144501. PMID: 31050461
Three-dimensional anisotropic turbulence in classical fluids tends towards isotropy and homogeneity with decreasing scales, allowing-eventually-the abstract model of homogeneous and isotropic turbulence to be relevant. We show here that the...

Daems D, Grossmann S, Lvov V, Procaccia I
Phys Rev E Stat Phys Plasmas Fluids Relat Interdiscip Topics . 2002 Apr; 60(6 Pt A):6656-62. PMID: 11970586
It was shown recently that the anomalous scaling of simultaneous correlation functions in turbulence is intimately related to the breaking of temporal scale invariance, which is equivalent to the appearance...

Lvov V, Pomyalov A, Procaccia I
Phys Rev E Stat Phys Plasmas Fluids Relat Interdiscip Topics . 2002 Apr; 60(4 Pt A):4175-84. PMID: 11970254
The Taylor hypothesis, which allows surrogating spatial measurements requiring many experimental probes by time series from one or two probes, is examined on the basis of a simple analytic model...

Arad I, Lvov V, Procaccia I
Phys Rev E Stat Phys Plasmas Fluids Relat Interdiscip Topics . 2002 Apr; 59(6):6753-65. PMID: 11969663
The theory of fully developed turbulence is usually considered in an idealized homogeneous and isotropic state. Real turbulent flows exhibit the effects of anisotropic forcing. The analysis of correlation functions...

Govindarajan R, Lvov V, Procaccia I
Phys Rev Lett . 2001 Nov; 87(17):174501. PMID: 11690275
Motivated by turbulent drag reduction by minute concentrations of polymers we study the effects of minor viscosity contrasts on the stability of hydrodynamic flows. The key player is a localized...

Arad I, Biferale L, Celani A, Procaccia I, Vergassola M
Phys Rev Lett . 2001 Nov; 87(16):164502. PMID: 11690207
We address the statistical theory of fields that are transported by a turbulent velocity field, both in forced and in unforced (decaying) experiments. With very few provisos on the transporting...

Davidovitch B, Jensen M, Levermann A, Mathiesen J, Procaccia I
Phys Rev Lett . 2001 Nov; 87(16):164101. PMID: 11690205
We study the nature of the phase transition in the multifractal formalism of the harmonic measure of diffusion limited aggregates. Contrary to previous work that relied on random walk simulations...

Barra F, Davidovitch B, Levermann A, Procaccia I
Phys Rev Lett . 2001 Oct; 87(13):134501. PMID: 11580593
It had been conjectured that diffusion limited aggregates and Laplacian growth patterns (with small surface tension) are in the same universality class. Using iterated conformal maps we construct a one-parameter...

Arad I, Procaccia I
Phys Rev E Stat Nonlin Soft Matter Phys . 2001 Jun; 63(5 Pt 2):056302. PMID: 11415001
We discuss the scaling exponents characterizing the power-law behavior of the anisotropic components of correlation functions in turbulent systems with pressure. The anisotropic components are conveniently labeled by the angular...

Phys Rev E Stat Nonlin Soft Matter Phys . 2001 Jun; 63(5 Pt 2):056118. PMID: 11414972
Extreme events have an important role which is sometimes catastrophic in a variety of natural phenomena, including climate, earthquakes, and turbulence, as well as in manmade environments such as financial...
