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…

Nonmutual torques and the unimportance of motility for long-range order in two-dimensional flocks
Lokrshi Prawar Dadhichi, Jitendra Kethapelli, Rahul Chajwa +2
As the constituent particles of a flock are polar and in a driven state, their interactions must, in general, be fore-aft asymmetric and non-reciprocal. Within a model that explici…

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…
