Wave-driven geostrophic vortices in rotating turbulence
Vladimir Parfenyev, Sergey Vergeles
We perform direct numerical simulations of rotating turbulence to investigate the mechanisms responsible for the maintenance of large-scale geostrophic vortices. We confirm that th…
Correlations in a weakly interacting two-dimensional random flow
I. V. Kolokolov, V. V. Lebedev, V. M. Parfenyev
We analytically examine fluctuations of vorticity excited by an external random force in two-dimensional fluid. We develop the perturbation theory enabling one to calculate nonline…
Statistical analysis of vortex condensate motion in two-dimensional turbulence
Vladimir Parfenyev
An inverse turbulent cascade in a periodic square box produces a coherent system-sized vortex dipole. We study the statistics of its motion by carrying out direct numerical simulat…
Sum-of-squares bounds on correlation functions in a minimal model of turbulence
Vladimir Parfenyev, Evgeny Mogilevskiy, Gregory Falkovich
We suggest a new computer-assisted approach to the development of turbulence theory. It allows one to impose lower and upper bounds on correlation functions using sum-of-squares po…
Footprints of loop extrusion in statistics of intra-chromosomal distances: an analytically solvable model
Sergey Belan, Vladimir Parfenyev
Active loop extrusion - the process of formation of dynamically growing chromatin loops due to the motor activity of DNA-binding protein complexes - is firmly established mechanism…
Profile of a Two-Dimensional Vortex Condensate Beyond the Universal Limit
Vladimir Parfenyev
It is well known that an inverse turbulent cascade in a finite () two-dimensional periodic domain leads to the emergence of a system-sized coherent vortex dipole. We…
Generation of stripe-like vortex flow by noncollinear waves on the water surface
S. V. Filatov, A. V. Poplevin, A. A. Levchenko +1
We have studied experimentally the generation of vortex flow by gravity waves with a frequency of 2.34 Hz excited on the water surface at an angle to…
Velocity profiles of cyclones and anticyclones in a rotating turbulent flow
Vladimir M. Parfenyev, Ivan A. Vointsev, Alyona O. Skoba +1
Strong rotation makes an underlying turbulent flow quasi-two-dimensional that leads to the upscale energy transfer. Recent numerical simulations show that under certain conditions,…
Conformational statistics of non-equilibrium polymer loops in Rouse model with active loop extrusion
Dmitry Starkov, Vladimir Parfenyev, Sergey Belan
Motivated by the recent experimental observations of the DNA loop extrusion by protein motors, in this paper we investigate the statistical properties of the growing polymer loops…
Virtual wave stress in deep-water crossed surface waves
Vladimir M. Parfenyev, Sergey S. Vergeles
Waves excited on the surface of deep water decay in time and/or space due to the fluid viscosity, and the momentum associated with the wave motion is transferred from the waves to…
Optimal Measurement Protocols in Quantum Zeno Effect
Sergey Belan, Vladimir Parfenyev
The quantum Zeno effect is the prediction, going back to Alan Turing, that the decay of an unstable system can be slowed down by measuring it frequently enough. It was also noticed…
Formation and decay of eddy currents generated by crossed surface waves
V. M. Parfenyev, S. V. Filatov, M. Yu. Brazhnikov +2
The mass-transport induced by crossed surface waves consists of the Stokes and Euler contributions which are very different in nature. The first contribution is a generalization of…
Universality in statistics of Stokes flow over no-slip wall with random roughness
Vladimir Parfenyev, Sergey Belan, Vladimir Lebedev
Stochastic roughness is widespread feature of natural surfaces and is an inherent by-product of most fabrication techniques. In view of rapid development of microfluidics, the impo…

Vladimir M. Parfenyev, Sergey S. Vergeles
Recently the generation of eddy currents by interacting surface waves was observed experimentally. The phenomenon provides the possibility for manipulation of particles which are i…

V. M. Parfenyev, S. S. Vergeles, V. V. Lebedev
Recently a theoretical scheme explaining the vorticity generation by surface waves in liquids was developed [S. Filatov et al., Phys. Rev. Lett. 116, 054501 (2016)]. Here we study…
Nonlinear generation of vorticity in thin smectic films
V. M. Parfenyev, S. S. Vergeles, V. V. Lebedev
We analyze a solenoidal motion in a vertically vibrated freely suspended thin smectic film. We demonstrate analytically that transverse oscillations of the film generate two-dimens…
