Yielding and large deviations in micellar gels: a model
Saroj Kumar Nandi, Bulbul Chakraborty, A. K. Sood +1
We present a simple model to account for the rheological behavior observed in recent experiments on micellar gels. The model combines attachment-detachment kinetics with stretching…
Soft Active Matter
M. C. Marchetti, J. -F. Joanny, S. Ramaswamy +4
In this review we summarize theoretical progress in the field of active matter, placing it in the context of recent experiments. Our approach offers a unified framework for the mec…
Mode-coupling theory for the dynamic heterogeneity in an aging glass: How Do Glassy Domains Grow?
Saroj Kumar Nandi, Sriram Ramaswamy
We construct the equations for the growth kinetics of an aging structural glass within mode-coupling theory through a non-stationary variant of the 3-density correlator defined in…
Live Soap: Order, Fluctuations and Instabilities in Active Smectics
Tapan Chandra Adhyapak, Sriram Ramaswamy, John Toner
We construct a hydrodynamic theory of noisy, apolar active smectics, in bulk suspension or on a substrate. Our predictions include: quasi-long-ranged smectic order in dimension d =…
Oscillatory settling in wormlike-micelle solutions: bursts and a long time scale
Nitin Kumar, Sayantan Majumdar, Aditya Sood +3
We study the dynamics of a spherical steel ball falling freely through a solution of entangled wormlike-micelles. If the sphere diameter is larger than a threshold value, the settl…
A Drop of Active Matter
Jean-Francois Joanny, Sriram Ramaswamy
We study theoretically the hydrodynamics of a fluid drop containing oriented filaments endowed with active contractile or extensile stresses and placed on a solid surface. The acti…
