Jamming by growth
Pawel Gniewek, Carl F Schreck, Oskar Hallatschek
Growth in confined spaces can drive cellular populations through a jamming transition from a fluid-like state to a solid-like state. Experiments have found that jammed budding yeas…
Vibrations of Jammed Disk Packings with Hertzian Interactions
Carl F. Schreck, Corey S. O'Hern, Mark D. Shattuck
Contact breaking and Hertzian interactions between grains can both give rise to nonlinear vibrational response of static granular packings. We perform molecular dynamics simulation…
Vibrations in jammed solids: Beyond linear response
Thibault Bertrand, Carl F. Schreck, Corey S. O'Hern +1
We propose a `phase diagram' for particulate systems that interact via purely repulsive contact forces, such as granular media and colloidal suspensions. We identify and characteri…
Response to Comment on Repulsive contact interactions make jammed particulate systems inherently nonharmonic'
Carl F. Schreck, Thibault Bertrand, Corey S. O'Hern +1
This is a response to the comment on our manuscript "Repulsive contact interactions make jammed particulate systems inherently nonharmonic" (Physical Review Letters 107 (2011) 0783…
Particle-scale reversibility in athermal particulate media below jamming
Carl F. Schreck, Robert S. Hoy, Mark D. Shattuck +1
We perform numerical simulations of athermal repulsive frictionless disks and spheres in two and three spatial dimensions undergoing cyclic quasi-static simple shear to investigate…
Rods are less fragile than spheres: Structural relaxation in dense liquids composed of anisotropic particles
Tianqi Shen, Carl Schreck, Bulbul Chakraborty +2
We perform extensive molecular dynamics simulations of dense liquids composed of bidisperse dimer- and ellipse-shaped particles in 2D that interact via repulsive contact forces. We…
