Polymer Knots in Thin Films: Thickness Dependence, Local Effects, and Stiffness
Maurice P. Schmitt, Hendrik Meyer, Peter Virnau
We study how confinement affects topology and conformations in polymer films of varying thickness . The knotting probability exhibits a maximum at intermediate thicknesses near…
Hybrid multiscale method for polymer melts: analysis and simulations
Ranajay Datta, Mária LukáÄová-MedviÄová, Andreas Schömer +1
We model the flow behaviour of dense melts of flexible and semiflexible ring polymers in the presence of walls using a hybrid multiscale approach. Specifically, we perform molecula…
Effect of simple shear on knotted polymer coils and globules
Andrey Milchev, Maurice P. Schmitt, Peter Virnau
We explore the effect of Couette flow on knotted linear polymer chains with extensive Molecular Dynamics (MD) simulations. Hydrodynamic interactions are accounted for by means of M…
Topological comparison of flexible and semiflexible chains in polymer melts with -chains
Maurice P. Schmitt, Sarah Wettermann, Kostas Ch. Daoulas +2
A central paradigm of polymer physics states that chains in melts behave like random walks as intra- and interchain interactions effectively cancel each other out. Likewise, -c…
Influence of Topology on Rheological Properties of Polymer Ring Melts
Ranajay Datta, Peter Virnau
We investigate with numerical simulations the influence of topology and stiffness on macroscopic rheological properties of polymer melts consisting of unknotted, knotted or concate…
