From a melt of rings to chromosome territories: the role of topological constraints in genome folding

JD Halverson, J Smrek, K Kremer… - Reports on Progress in …, 2014 - iopscience.iop.org
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 …

Celebrating Soft Matter's 10th Anniversary: Topology matters: structure and dynamics of ring polymers

D Richter, S Gooßen, A Wischnewski - Soft Matter, 2015 - pubs.rsc.org
Considering topology among all polymer architectures polymer rings are unique, as they are
the simplest closed structures without ends. In this review we present recent experimental …

Self-similar conformations and dynamics in entangled melts and solutions of nonconcatenated ring polymers

T Ge, S Panyukov, M Rubinstein - Macromolecules, 2016 - ACS Publications
A scaling model of self-similar conformations and dynamics of nonconcatenated entangled
ring polymers is developed. Topological constraints force these ring polymers into compact …

50th Anniversary Perspective: Polymer ConformationA Pedagogical Review

ZG Wang - Macromolecules, 2017 - ACS Publications
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 …

Ring polymers in the melt state: the physics of crumpling

A Rosa, R Everaers - Physical review letters, 2014 - APS
The conformational statistics of ring polymers in melts or dense solutions is strongly affected
by their quenched microscopic topological state. The effect is particularly strong for …

Topology Matters: Conformation and Microscopic Dynamics of Ring Polymers

M Kruteva, J Allgaier, D Richter - Macromolecules, 2023 - ACS Publications
Ring polymers have fascinated theorists, simulators, and experimentalists as they are the
simplest polymer without ends, giving rise to important topology related properties. We …

Entanglement length scale separates threading from branching of unknotted and non-concatenated ring polymers in melts

MA Ubertini, J Smrek, A Rosa - Macromolecules, 2022 - ACS Publications
Current theories on the conformation and dynamics of unknotted and non-concatenated ring
polymers in melt conditions describe each ring as a tree-like double-folded object. While …

Annealed lattice animal model and Flory theory for the melt of non-concatenated rings: towards the physics of crumpling

AY Grosberg - Soft Matter, 2014 - pubs.rsc.org
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 …

Threading of unconcatenated ring polymers at high concentrations: double-folded vs time-equilibrated structures

J Smrek, K Kremer, A Rosa - ACS macro letters, 2019 - ACS Publications
Unconcatenated ring polymers in concentrated solutions and melt are remarkably well
described as double-folded conformations on randomly branched primitive trees. This …

Anomalous diffusion in fractal globules

MV Tamm, LI Nazarov, AA Gavrilov, AV Chertovich - Physical review letters, 2015 - APS
The fractal globule state is a popular model for describing chromatin packing in eukaryotic
nuclei. Here we provide a scaling theory and dissipative particle dynamics computer …
