Critical scaling and aging in cooling systems near the jamming transition
D. A. Head
We conduct athermal simulations of freely-cooling, viscous soft spheres around the jamming transition density ϕ_{J}, and find evidence for a growing length ξ(t) that governs relaxa…
Modeling the elastic deformation of polymer crusts formed by sessile droplet evaporation
D. A. Head
Evaporating droplets of polymer or colloid solution may produce a glassy crust at the liquid-vapour interface, which subsequently deforms as an elastic shell. For sessile droplets,…
The mechanical response of semiflexible networks to localized perturbations
D. A. Head, A. J. Levine, F. C. MacKintosh
Previous research on semiflexible polymers including cytoskeletal networks in cells has suggested the existence of distinct regimes of elastic response, in which the strain field i…
A mean field description of jamming in non-cohesive frictionless particulate systems
D. A. Head
A theory for kinetic arrest in isotropic systems of repulsive, radially-interacting particles is presented that predicts exponents for the scaling of various macroscopic quantities…
Distinct regimes of elastic response and deformation modes of cross-linked cytoskeletal and semiflexible polymer networks
D. A. Head, A. J. Levine, F. C. MacKintosh
Semiflexible polymers such as filamentous actin play a vital role in the mechanical behavior of cells, yet the basic properties of cross-linked F-actin networks remain poorly under…
Non-universality of elastic exponents in random bond-bending networks
D. A. Head, F. C. MacKintosh, A. J. Levine
We numerically investigate the rigidity percolation transition in two-dimensional flexible, random rod networks with freely rotating cross-links. Near the transition, networks are…
