Density-driven reentrant polymer transitions via saturable bridging crowders
Monmee Phukan, Hitesh Garg, Satyavani Vemparala
The paper uses coarse‑grained molecular dynamics simulations to show that the volume fraction of attractive crowders alone can drive a polymer to collapse and then re‑expand (reent…
Self-organization and memory formation in two-dimensional jammed deformable matter under cyclic compression
Rahul Nayak, Satyavani Vemparala, Pinaki Chaudhuri
We study the athermal mechanical response of deformable ring assemblies to quasistatic compression. Beyond jamming, further densification induces buckling of rings, resulting in ma…
Glassy dynamics in two-dimensional ring polymers: size versus stiffness polydispersity
Rahul Nayak, Pinaki Chaudhuri, Satyavani Vemparala
Soft glassy materials often consist of deformable objects. Here, we use a two-dimensional assembly of semi-flexible ring polymers as a model system to investigate how polydispersit…
Accelerated Collapse Kinetics of Charged Polymers in Good Solvent: Role of Counterion Condensation
Susmita Ghosh, Satyavani Vemparala
We investigate the collapse kinetics of charged polymers (polyelectrolytes) induced by counterion condensation using coarse-grained molecular dynamics simulations. Under good solve…
Aging of ring polymeric topological glass formers via thermal quench
Arabinda Behera, Projesh Roy, Pinaki Chaudhuri +1
We investigate the dynamical response of glass-forming systems composed of topologically constrained ring polymers subjected to an instantaneous thermal quench, employing large-sca…
Bridging-induced Aggregation in Neutral Polymers: Dynamics and Morphologies
Hitesh Garg, Satyavani Vemparala
Using molecular dynamics simulations, we investigate the aggregation behavior of neutral stiff (rod-like) and flexible polymer chains mediated by attractive crowders. Attractive cr…
