The End of Chaos at the Ideal Glass Transition
Zi-Long Wang, Jack F. Douglas, Matteo Baggioli +2
The ideal glass transition has often been associated with the extrapolated vanishing of configurational entropy , yet how this thermodynamic criterion is reflected in microsco…
Effect of Added Salts on the Interfacial Dynamics of Monovalent Metal Ions and Model Water-Soluble Polymers
Soumik Ghosh, Jack F. Douglas, Francis W. Starr
Traditional theories of electrolyte and polyelectrolyte solutions overlook ion and polymer hydration, yielding an overly idealized perspective of the thermodynamic and dynamic prop…
Effect of Temperature and Added Salt on a Model Polyzwitterion Polymer in Dilute Solution
Soumik Ghosh, Vivek M. Prabhu, Jack F. Douglas
The competitive interactions arising from the proximity of positive and negatively charged groups in the monomers in polyzwitterions (PZ) makes these polymers have properties simil…
String Model Predicts Relaxation in Sheared Glass-Forming Liquids
Zi-Long Wang, Qi-Lu Yuan, Yun-Jiang Wang +4
Understanding how structural relaxation evolves from equilibrium to nonequilibrium conditions remains a central problem in glass physics. Using simulations of model glass formers u…
Tunable Cooperative Motion, Rigidity, and Glassy Dynamics in Knotted Ring Polymer Melts
Yue-Tong Dong, Jack F. Douglas, Wen-Sheng Xu
We present a molecular dynamics study of the influence of knot complexity and molecular mass on glass formation upon cooling in knotted ring polymer melts. We find that cooperative…
