Macroscopic fluctuation theory and first-passage properties of surface diffusion.

Physical review. E

Meerson B, Vilenkin A.
PMID: 26986272
Phys Rev E. 2016 Feb;93(2):020102. doi: 10.1103/PhysRevE.93.020102. Epub 2016 Feb 08.

We investigate nonequilibrium fluctuations of a solid surface governed by the stochastic Mullins-Herring equation with conserved noise. This equation describes surface diffusion of adatoms accompanied by their exchange between the surface and the bulk of the solid, when desorption...

Dynamics of fractal dimension during phase ordering of a geometrical multifractal.

Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics

Peleg A, Meerson B.
PMID: 11088637
Phys Rev E Stat Phys Plasmas Fluids Relat Interdiscip Topics. 2000 Aug;62(2):1764-8. doi: 10.1103/physreve.62.1764.

A simple multifractal coarsening model is suggested that can explain the observed dynamical behavior of the fractal dimension in a wide range of coarsening fractal systems. It is assumed that the minority phase (an ensemble of droplets) at t=0...

Normal scaling in globally conserved interface-controlled coarsening of fractal clusters.

Physical review. E, Statistical, nonlinear, and soft matter physics

Peleg A, Conti M, Meerson B.
PMID: 11580414
Phys Rev E Stat Nonlin Soft Matter Phys. 2001 Sep;64(3):036127. doi: 10.1103/PhysRevE.64.036127. Epub 2001 Aug 30.

We find that globally conserved interface-controlled coarsening of diffusion-limited aggregates exhibits dynamic scale invariance (DSI) and normal scaling. This is demonstrated by a numerical solution of the Ginzburg-Landau equation with a global conservation law. The general sharp-interface limit of...

Symmetry-breaking instability and strongly peaked periodic clustering states in a driven granular gas.

Physical review. E, Statistical, nonlinear, and soft matter physics

Livne E, Meerson B, Sasorov PV.
PMID: 11863511
Phys Rev E Stat Nonlin Soft Matter Phys. 2002 Feb;65(2):021302. doi: 10.1103/PhysRevE.65.021302. Epub 2002 Jan 09.

An ensemble of inelastically colliding grains driven by a horizontally vibrating wall in two dimensions exhibits clustering. Working in the limit of nearly elastic collisions and employing granular hydrodynamics, we predict, by a marginal stability analysis, a spontaneous symmetry...

Fluctuations provide strong selection in Ostwald ripening.

Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics

Meerson B.
PMID: 11970114
Phys Rev E Stat Phys Plasmas Fluids Relat Interdiscip Topics. 1999 Sep;60(3):3072-5. doi: 10.1103/physreve.60.3072.

A selection problem that appears in the Lifshitz-Slyozov (LS) theory of Ostwald ripening is reexamined. The problem concerns selection of a self-similar distribution function (DF) of the minority domains with respect to their sizes from a whole one-parameter family...

Area-preserving dynamics of a long slender finger by curvature: a test case for globally conserved phase ordering.

Physical review. E, Statistical, nonlinear, and soft matter physics

Peleg A, Meerson B, Vilenkin A, Conti M.
PMID: 11415167
Phys Rev E Stat Nonlin Soft Matter Phys. 2001 Jun;63(6):066101. doi: 10.1103/PhysRevE.63.066101. Epub 2001 May 11.

A long and slender finger can serve as a simple "test bed" for different phase-ordering models. In this work, the globally conserved, interface-controlled dynamics of a long finger is investigated, analytically and numerically, in two dimensions. An important limit...

Emergence of stability in a stochastically driven pendulum: beyond the Kapitsa pendulum.

Physical review. E, Statistical, nonlinear, and soft matter physics

Simons YB, Meerson B.
PMID: 19905368
Phys Rev E Stat Nonlin Soft Matter Phys. 2009 Oct;80(4):042102. doi: 10.1103/PhysRevE.80.042102. Epub 2009 Oct 27.

We consider a prototypical nonlinear system which can be stabilized by multiplicative noise: an underdamped nonlinear pendulum with a stochastically vibrating pivot. A numerical solution of the pertinent Fokker-Planck equation shows that the upper equilibrium point of the pendulum...

Scaling and self-similarity in an unforced flow of inviscid fluid trapped inside a viscous fluid in a Hele-Shaw cell.

Physical review letters

Vilenkin A, Meerson B, Sasorov PV.
PMID: 16486830
Phys Rev Lett. 2006 Feb 03;96(4):044504. doi: 10.1103/PhysRevLett.96.044504. Epub 2006 Feb 01.

We investigate quasi-two-dimensional relaxation, by surface tension, of a long straight stripe of inviscid fluid trapped inside a viscous fluid in a Hele-Shaw cell. Combining analytical and numerical solutions, we describe the emergence of a self-similar dumbbell shape and...

Navier-Stokes hydrodynamics of thermal collapse in a freely cooling granular gas.

Physical review. E, Statistical, nonlinear, and soft matter physics

Kolvin I, Livne E, Meerson B.
PMID: 20866801
Phys Rev E Stat Nonlin Soft Matter Phys. 2010 Aug;82(2):021302. doi: 10.1103/PhysRevE.82.021302. Epub 2010 Aug 13.

We show that, in dimension higher than one, heat diffusion and viscosity cannot arrest thermal collapse in a freely evolving dilute granular gas, even in the absence of gravity. Thermal collapse involves a finite-time blowup of the gas density....

Population extinction risk in the aftermath of a catastrophic event.

Physical review. E, Statistical, nonlinear, and soft matter physics

Assaf M, Kamenev A, Meerson B.
PMID: 19257021
Phys Rev E Stat Nonlin Soft Matter Phys. 2009 Jan;79(1):011127. doi: 10.1103/PhysRevE.79.011127. Epub 2009 Jan 29.

We investigate how a catastrophic event (modeled as a temporary fall of the reproduction rate) increases the extinction probability of an isolated self-regulated stochastic population. Using a variant of the Verhulst logistic model as an example, we combine the...
