A review of the main elasticity models of flexible polymer networks is presented. Classical
models of phantom networks suggest that the networks have a tree-like structure. The …

Steady-state shear viscosity η (γ̇) of unconcatenated ring polymer melts as a function of the
shear rate γ̇ is studied by a combination of experiments, simulations, and theory …

Chromosome large‐scale organization is a beautiful example of the interplay between
physics and biology. DNA molecules are polymers and thus belong to the class of molecules …

The study of the conformation properties of macromolecules is at the heart of polymer
science. Essentially all physical properties of polymers are manifestations of the underlying …

The topological state of chromosomes determines their mechanical properties, dynamics,
and function. Recent work indicated that interphase chromosomes are largely free of …

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

In the melt state at equilibrium, entangled nonconcatenated ring macromolecules adapt
more compact conformations compared to their linear analogs and do not form an …

Molecular dynamics simulations confirm recent extensional flow experiments showing ring
polymer melts exhibit strong extension-rate thickening of the viscosity at Weissenberg …

Ring polymers have fascinated scientists for decades, but experimental progress has been
challenging due to the presence of linear chain contaminants that fundamentally alter …

The motion of nanoparticles in a polymer matrix is dictated by the intricate coupling of the
nanoparticles and surrounding polymers. Various length-and time-scale dependent features …
