Intermediate-range order governs dynamics in dense colloidal liquids
Navneet Singh, Zhen Zhang, A. K. Sood +2
The conventional wisdom is that liquids are completely disordered and lack non-trivial structure beyond nearest-neighbor distances. Recent observations have upended this view and d…
Shear jamming and fragility in fractal suspensions under confinement
Sarika C. K., Sayantan Majumdar, A. K. Sood
Under applied stress, the viscosity of many dense particulate suspensions increases drastically, a response known as discontinuous shear-thickening (DST). In some cases, the applie…
Motile topological defects hinder dynamical arrest in dense liquids of active ellipsoids
Pragya Arora, A K Sood, Rajesh Ganapathy
Recent numerical studies have identified the persistence time of active motion as a critical parameter governing glassy dynamics in dense active matter. Here we studied dynamics in…
Negative differential resistance state in the free-flux-flow regime of driven vortices in a single crystal of 2H-NbS
Biplab Bag, Sourav M. Karan, Gorky Shaw +3
Time series measurements in 2H-NbS crystal had unravelled a drive induced transition wherein the critical current (Ic) changes from a low to a high Ic jammed vortex state, via…
Shear-induced ordering of nano-pores and instabilities in concentrated surfactant mesh phases
Pradip K. Bera, Vikram Rathee, Rema Krishnaswamy +1
Mixed surfactant systems with strongly bound counterions show many interesting phases such as the random mesh phase consisting of a disordered array of defects (water-filled nano-p…
Universality and Scaling Behaviour of Injected Power in Elastic Turbulence in Worm-like Micellar Gel
Sayantan Majumdar, A. K. Sood
We study the statistical properties of spatially averaged global injected power fluctuations for Taylor-Couette flow of a worm-like micellar gel formed by surfactant CTAT. At suffi…
