We provide a Perspective on recent findings in extensional rheology for polymer melts and
solutions with different macromolecular architectures. For linear polymer systems, we focus …

Ring polymers have fascinated theorists, simulators, and experimentalists as they are the
simplest polymer without ends, giving rise to important topology related properties. We …

Three subjects in polymer and soft matter physics are outlined in the present article. The first
relates to concepts of an ideal glass transition. We describe work on ultra‐stable glass …

Linear viscoelastic properties in both melt and solution states are reported for a series of
poly (3, 6-dioxa-1, 8-octanedithiol)(polyDODT) made by reversible radical recombination …

Extensive molecular simulations are applied to characterize the equilibrium dynamics,
entanglement topology, and nonlinear extensional rheology of symmetric ring-linear …

Connecting the viscoelastic behavior of stressed ring melts to the various forms of
entanglement that can emerge in such systems is still an open challenge. Here, we consider …

We use computer simulations to study a system of two unlinked ring polymers, whose length
and bending stiffness are systematically varied. We derive the effective potentials between …

How local stresses propagate through polymeric fluids, and, more generally, how
macromolecular dynamics give rise to viscoelasticity are open questions vital to wide …

The behavior of giant amphiphilic molecules at the air–water interface has become a subject
of concern to researchers. Small changes in the molecular structure can cause obvious …

We derive and parameterize effective interaction potentials between a multitude of different
types of ring polymers and linear chains, varying the bending rigidity and solvent quality for …
