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…
A shape-driven reentrant jamming transition in confluent monolayers of synthetic cell-mimics
Pragya Arora, Souvik Sadhukhan, Saroj Kumar Nandi +3
Many critical biological processes, like wound healing, require confluent cell monolayers/bulk tissues to transition from a jammed solid-like to a fluid-like state. Although numeri…
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…
