We review pro and contra of the hypothesis that generic polymer properties of topological
constraints are behind many aspects of chromatin folding in eukaryotic cells. For that …

The relaxation, diffusion and translocation dynamics of single linear polymer chains in
confinement is briefly reviewed with emphasis on the comparison between theoretical …

The dynamics of entangled flexible polymers is dominated by physics general to many
chemical systems. It is an appealing interdisciplinary field where experimental and …

After many years of intense research, most aspects of the motion of entangled polymers
have been understood. Long linear and branched polymers have a characteristic …

Molecular dynamics simulations were conducted to investigate the structural properties of
melts of nonconcatenated ring polymers and compared to melts of linear polymers. The …

It is shown that the kinetics of collapse of a polymer coil consisting of N segments after an
abrupt decrease of temperature is a two-stage process if N>> Ne. The first stage takes a time …

A scaling model of self-similar conformations and dynamics of nonconcatenated entangled
ring polymers is developed. Topological constraints force these ring polymers into compact …

We discuss the elastic modulus G and swelling/deswelling behavior of networks as a
function of their concentration< t> and their preparation state. Simple scaling ideas …

We present a simple scaling theory of the dynamics of a ring polymer in a gel. In the
absence of excluded volume interactions, we predict that the translational diffusion …

A Flory theory is constructed for a long polymer ring in a melt of unknotted and non-
concatenated rings. The theory assumes that the ring forms an effective annealed branched …
