Reentrant melting of scarred odd crystals by self-shear
Uttam Tiwari, Pragya Arora, A K Sood +3
Spatial confinement can induce geometrical frustration in condensed phases, giving rise to topological defects that confer materials with new and exotic properties. Here, we experi…
Edge states, pairing, and sorting of motile chiral particles
Raushan Kant, Ananyo Maitra, A K Sood +1
We present experiments on chiral active polar particles, realised as vibrated granular rods, revealing evidence for ``skipping orbits'' at hard boundaries. These classical edge sta…
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…
Anisotropic Isometric Fluctuation Relations in experiment and theory on a self-propelled rod
Nitin Kumar, Harsh Soni, Sriram Ramaswamy +1
The Isometric Fluctuation Relation (IFR) [P.I. Hurtado et al., PNAS 108, 7704 (2011)] relates the relative probability of current fluctuations of fixed magnitude in different spati…
Oscillatory settling in wormlike-micelle solutions: bursts and a long time scale
Nitin Kumar, Sayantan Majumdar, Aditya Sood +3
We study the dynamics of a spherical steel ball falling freely through a solution of entangled wormlike-micelles. If the sphere diameter is larger than a threshold value, the settl…
