Active Caustics
Rahul Chajwa, Rajarshi, Rama Govindarajan +1
Inertial particles (IPs) in vortical fluid flow cluster strongly, forming singular structures termed caustics for their resemblance to focal surfaces in optics. Here we show that s…

Bulk condensation by an active interface
Raushan Kant, Rahul Kumar Gupta, Harsh Soni +2
We present experiments, supported by mechanically detailed simulations, establishing bulk vapor-liquid condensation of a hard-bead fluid by a tiny population of orientable motile g…

Dynamics and clustering of sedimenting disc lattices
Harshit Joshi, Rahul Chajwa, Sriram Ramaswamy +2
Uniform arrays of particles tend to cluster as they sediment in viscous fluids. Shape anisotropy of the particles enriches these dynamics by modifying the mode-structure and the re…
