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 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…
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…
Tuning the performance of a micrometer-sized Stirling engine through reservoir engineering
Niloyendu Roy, Nathan Leroux, A K Sood +1
Colloidal heat engines are paradigmatic models to understand the conversion of heat into work in a noisy environment - a domain where biological and synthetic nano/micro machines f…
