Design Principles for Programmable Topological Soft Networks
Andrea Bonato, Davide Marenduzzo, Enzo Orlandini
Physical crosslinks in conventional gels are static and spatially localised, fundamentally limiting their capacity to adapt, self-heal, or perform mechanical work. Topological gels…
Topological Signatures of Hardness and Structural Order in Network-Forming Materials
Yair Augusto Gutiérrez Fosado, Ayobami Daramola, Davide Marenduzzo +1
Understanding how the topology of network forming materials influences their physical properties remains a longstanding challenge. Here, we investigate the topology of experimental…
Topological delocalisation of confined 3D active nematics
Louise C. Head, Pasquale Digregorio, Davide Marenduzzo +3
Defect lines in 3D active nematic systems are intriguing topological singularities whose out-of-equilibrium dynamics remain elusive in confined settings. Here, we numerically study…
Flow of deformable droplets: self-pinned glasses and string-like flow
Achille Quarante, Michael Chiang, Davide Marenduzzo +1
We investigate, through numerical simulations, the rheology of a dry suspension of deformable droplets under pressure-driven flow. The system exhibits two force-driven dynamical tr…
Geometry and relaxation dynamics of nematic loops
F. Aprile, A. J. H. Houston, G. Gonnella +3
Disclination lines in three-dimensional nematic liquid crystals generically form closed loops whose topology is classified by homotopy theory. While this classification successfull…
On the geometric algebras of the Ising model
N. Johnson, D. Marenduzzo, A. Morozov +2
We revisit the classical transfer matrix solution of the one- and two-dimensional Ising model from the perspective of Clifford and conformal geometric algebras. Building on Kaufman…
Braiding and exchange statistics of liquid crystalline Majorana quasiparticles
A. I. Tóth, G. Negro, A. D. Huxley +1
Liquid crystalline defects in 3D can be viewed as geometric spinors, whose emergent properties are reminiscent of those of topological excitations in quantum condensed matter, such…
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…
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…
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…
Supercoiling DNA with a free end
Daniela Moretti, Giuseppe Gonnella, Antonio Suma +3
In this work, we combine coarse-grained Brownian dynamics simulations and mean-field theory to study supercoiling dynamics, as well as the steady-state profiles of twist and writhe…
Spontaneous phase separation and pattern formation in a lyotropic nematic mixture
A. Bensabat, O. Skelton, J. Arlt +5
Lyotropic liquid crystals can display rich phase behaviour and self-organisation, yet the physical principles underlying their self-assembly into large scale patterns remains under…
