Correlations of fluctuations of two-dimensional flow forced by a random force on top of a shear flow
Igor V. Kolokolov, Vladimir V. Lebedev
We examine fluctuations of vorticity excited by an external random force in two-dimensional fluid in the presence of a strong external shear flow. The problem is motivated by the a…
Universal Velocity Profile for Coherent Vortices in Two-Dimensional Turbulence
M. Chertkov, I. Kolokolov, V. Lebedev
Two-dimensional turbulence generated in a finite box produces large-scale coherent vortices coexisting with small-scale fluctuations. We present a rigorous theory explaining the $η…
Explicit solution of the optimal fluctuation problem for an elastic string in random potential
I. V. Kolokolov, S. E. Korshunov
The free-energy distribution function of an elastic string in a quenched random potential, P(F), is investigated with the help of the optimal-fluctuation approach. The form of the…
Statistics of Polymer Extension in a Random Flow with Mean Shear
M. Chertkov, I. Kolokolov, V. Lebedev +1
Considering the dynamics of a polymer with finite extensibility placed in a chaotic flow with large mean shear, we explain how the statistics of polymer extension changes with Weis…
Tumbling of Polymers in a Random Flow with Mean Shear
M. Chertkov, I. Kolokolov, V. Lebedev +1
A polymer placed in chaotic flow with large mean shear tumbles, making a-periodic flips. We describe the statistics of angular orientation, as well as of tumbling time (separating…
Long-time dynamics of the infinite-temperature Heisenberg magnet
Michael Chertkov, Igor Kolokolov
Infinite-temperature long-time dynamics of Heisenberg model is investigated. It is shown that the qua…
