Persistent Homology Reveals the Role of Stiffness in Forming Topological Glasses in Dense Solutions of Ring Polymers
Shota Goto, Takenobu Nakamura, Davide Michieletto +2
Ring polymers are characterized by topology-specific entanglements called threadings. In the limit of large rings, it is conjectured that a "topological glass" should emerge due to…

Threading-Induced Dynamical Transition in Tadpole-Shaped Polymers
Angelo Rosa, Jan Smrek, Matthew S Turner +1
The relationship between polymer topology and bulk rheology remains a key question in soft matter physics. Architecture-specific constraints (or threadings) are thought to control…

Topological Sieving of Rings According to their Rigidity
Stefano Iubini, Enzo Orlandini, Davide Michieletto +1
We present a novel mechanism for resolving the mechanical rigidity of nanoscopic circular polymers that flow in a complex environment. The emergence of a regime of negative differe…
