Topological localisation and motility of active knots
Andrea Bonato, Davide Marenduzzo, Enzo Orlandini +1
Nonequilibrium active polymers provide a minimal framework to investigate biopolymers such as DNA and chromatin under the action of molecular motors. Here we study active ring poly…
Nucleoid clustering drives stepwise expansion and segregation of replicating bacterial chromosomes
Giada Forte, Enzo Orlandini, Davide Marenduzzo
Bacterial chromosome replication occurs in the absence of a canonical spindle apparatus; yet it reliably produces organised and segregated genomes. While both passive and active me…
Field-induced phase transitions in ferro-antiferromagnetic diblock copolymers
Alberto Raiola, Emanuele Locatelli, Davide Marenduzzo +1
We study the equilibrium properties of a model of magnetic diblock copolymer where each monomer is decorated with an Ising-like spin. Spins interact ferromagnetically within each b…
Topological weight and structural diversity of polydisperse chromatin loop networks
Andrea Bonato, Enrico Carlon, Sergey Kitaev +2
Current biophysical models for transcriptionally active chromatin view this as a polymer with sticky sites, mimicking transcription units such as promoters and enhancers which inte…
