Anisotropic medium-range order uncovers dynamic crossovers in glass-forming liquids
Kamlesh Mishra, Rajesh Ganapathy, Walter Kob
On cooling liquids towards their glass-transition temperature, the dramatic increase of their relaxation times is accompanied by changes in particle dynamics at two distinct temper…
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…
Intermediate-range order governs dynamics in dense colloidal liquids
Navneet Singh, Zhen Zhang, A. K. Sood +2
The conventional wisdom is that liquids are completely disordered and lack non-trivial structure beyond nearest-neighbor distances. Recent observations have upended this view and d…
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…
Synergistic action in colloidal heat engines coupled by non-conservative flows
Sudeesh Krishnamurthy, Rajesh Ganapathy, A. K. Sood
Collective operation of multiple engines to achieve a common objective is a vital step in the design of complex machines. Recent studies have reduced the length scales of engine de…
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…
