Effects of linking topology on the shear response of connected ring polymers: Catenanes and bonded rings flow differently

RA Farimani, Z Ahmadian Dehaghani, CN Likos… - Physical Review Letters, 2024 - APS
We perform computer simulations of mechanically linked (poly [2] catenanes, PC) and
chemically bonded (bonded rings, BR) pairs of self-avoiding ring polymers in steady shear …

Phase separation in soft repulsive polymer mixtures: foundation and implication for chromatin organization

N Iso, Y Norizoe, T Sakaue - Soft Matter, 2024 - pubs.rsc.org
Given the wide range of length scales, the analysis of polymer systems often requires coarse-
graining, for which various levels of description may be possible depending on the …

Single-molecule analysis of solvent-responsive mechanically interlocked ring polymers and the effects of nanoconfinement from coarse-grained simulations

D Becerra, AR Klotz, LM Hall - The Journal of Chemical Physics, 2024 - pubs.aip.org
In this study, we simulate mechanically interlocked semiflexible ring polymers inspired by
the minicircles of kinetoplast DNA (kDNA) networks. Using coarse-grained molecular …
