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…
A Single-granule Stirling Heat Engine
Niloyendu Roy, Pragya Arora, A K Sood +1
Single-particle heat engines at atomic and colloidal scales obey the universal thermodynamic bounds on work and efficiency. Here, we translate these principles to the macroscale by…
Motile topological defects hinder dynamical arrest in dense liquids of active ellipsoids
Pragya Arora, A K Sood, Rajesh Ganapathy
Recent numerical studies have identified the persistence time of active motion as a critical parameter governing glassy dynamics in dense active matter. Here we studied dynamics in…
Emergent Stereoselective Interactions and Self-recognition in Polar Chiral Active Ellipsoids
Pragya Arora, A K Sood, Rajesh Ganapathy
In many active matter systems, particle trajectories have a well-defined handedness or chirality. Whether such chiral activity can introduce stereoselective interactions between pa…
