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…
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…
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…
Dynamics of Ordered Active Columns: Flows, Twists, and Waves
S. J. Kole, Gareth P. Alexander, Ananyo Maitra +1
We formulate the hydrodynamics of active columnar phases, with two-dimensional translational order in the plane perpendicular to the columns and no elastic restoring force for rela…
Defect turbulence in a dense suspension of polar, active swimmers
Navdeep Rana, Rayan Chatterjee, Sunghan Ro +3
We study the effects of inertia in dense suspensions of polar swimmers. The hydrodynamic velocity field and the polar order parameter field describe the dynamics of the suspension.…
Two-temperature activity induces liquid-crystal phases inaccessible in equilibrium
Jayeeta Chattopadhyay, Sriram Ramaswamy, Chandan Dasgupta +1
In equilibrium hard-rod fluids, and in effective hard-rod descriptions of anisotropic soft-particle systems, the transition from the isotropic (I) phase to the nematic phase (N) is…
