Viscosity control of the dynamic self-assembly in ferromagnetic suspensions
D. L. Piet, A. V. Straube, A. Snezhko +1
Recent studies of dynamic self-assembly in ferromagnetic colloids suspended in liquid-air or liquid-liquid interfaces revealed a rich variety of dynamic structures ranging from lin…
Partially fluidized shear granular flows: Continuum theory and MD simulations
D. Volfson, L. S. Tsimring, I. S. Aranson
The continuum theory of partially fluidized shear granular flows is tested and calibrated using two dimensional soft particle molecular dynamics simulations. The theory is based on…
Velocity Fluctuations in Electrostatically Driven Granular Media
I. S. Aranson, J. S. Olafsen
We study experimentally the particle velocity fluctuations in an electrostatically driven dilute granular gas. The experimentally obtained velocity distribution functions have stro…
Phase Separation and Coarsening in Electrostatically Driven Granular Media
I. S. Aranson, B. Meerson, P. V. Sasorov +1
A continuum model for the phase separation and coarsening, observed in electrostatically driven granular media, is formulated in terms of a Ginzburg-Landau equation subject to cons…
Vortex avalanches and magnetic flux fragmentation in superconductors
Igor Aranson, Alex Gurevich, Valerii Vinokur
We report results of numerical simulations of non isothermal dendritic flux penetration in type-II superconductors. We propose a generic mechanism of dynamic branching of a propaga…
Stick-slip friction and nucleation dynamics of ultra-thin liquid films
I. S. Aranson, L. S. Tsimring, V. M. Vinokur
We develop the theory for stick-slip motion in ultra-thin liquid films confined between two moving atomically-flat surfaces. Our model is based on hydrodynamic equation for the flo…
Interaction of Vortices in Complex Vector Field and Stability of a ``Vortex Molecule''
Igor S. Aranson, Len M. Pismen
We consider interaction of vortices in the vector complex Ginzburg--Landau equation (CVGLE). In the limit of small field coupling, it is found analytically that the interaction bet…
Nucleation of vortices by rapid thermal quench
I. S. Aranson, N. B. Kopnin, V. M. Vinokur
We show that vortex nucleation in superfluid He by rapid thermal quench in the presence of superflow is dominated by a transverse instability of the moving normal-superfluid in…
Controlled Dynamics of Interfaces in a Vibrated Granular Layer
I. Aranson, D. Blair, W. Kwok +5
We present experimental study of a topological excitation, {\it interface}, in a vertically vibrated layer of granular material. We show that these interfaces, separating regions o…
Hexagons and Interfaces in a Vibrated Granular Layer
I. S. Aranson, L. S. Tsimring, V. M. Vinokur
The order parameter model based on parametric Ginzburg-Landau equation is used to describe high acceleration patterns in vibrated layer of granular material. At large amplitude of…
Nucleation and Growth of Normal Phase in Thin Superconducting Strips
I. Aranson, B. Ya. Shapiro, V. Vinokur
We investigate the kinetics of normal phase nucleation and flux line condensation in the type-II superconductors by numerical study of the time-dependent Ginzburg-Landau equation.…
