Activity enhances heterogenous dynamics in 2D granular glasses
Chetan Yadav, Narayanan Menon
We study the effect of self-propulsion in the approach to the glassy regime of 2D bidisperse mixtures of frictional discs, confined to a horizontal plane, and fluidized by vertical…
Peeling from a liquid
Deepak Kumar, Nuoya Zhou, Fabian Brau +2
We establish the existence of a cusp in the curvature of a solid sheet at its contact with a liquid subphase. We study two configurations in floating sheets where the solid-vapor-l…
Shapes of a filament on the surface of a bubble
S Ganga Prasath, Joel Marthelot, Rama Govindarajan +1
The shape assumed by a slender elastic structure is a function both of the geometry of the space in which it exists and the forces it experiences. We explore by experiments and the…
Wetting and wrapping of a floating droplet by a thin elastic filament
S Ganga Prasath, Joel Marthelot, Narayanan Menon +1
We study the wetting of a thin elastic filament floating on a fluid surface by a droplet of another, immiscible fluid. This quasi-2D experimental system is the lower-dimensional co…
Waves, Algebraic Growth and Clumping in Sedimenting Disk Arrays
Rahul Chajwa, Narayanan Menon, Sriram Ramaswamy +1
An array of spheres descending slowly through a viscous fluid always clumps [J.M. Crowley, J. Fluid Mech. {\bf 45}, 151 (1971)]. We show that anisotropic particle shape qualitative…
Kepler orbits of settling discs
Rahul Chajwa, Narayanan Menon, Sriram Ramaswamy
The collective dynamics of objects moving through a viscous fluid is complex and counterintuitive. A key to understanding the role of nontrivial particle shape in this complexity i…
