Low-frequency vibrations of soft colloidal glasses
Ke Chen, Wouter G. Ellenbroek, Zexin Zhang +8
We conduct experiments on two-dimensional packings of colloidal thermosensitive hydrogel particles whose packing fraction can be tuned above the jamming transition by varying the t…
Elementary Excitation Modes in a Granular Glass above Jamming
Carolina Brito, Olivier Dauchot, Giulio Biroli +1
The dynamics of granular media in the jammed, glassy region is described in terms of "modes", by applying a Principal Component Analysis (PCA) to the covariance matrix of the posit…
Local Coulomb versus Global Failure Criterion for Granular Packings
Silke Henkes, Carolina Brito, Olivier Dauchot +1
Contacts at the Coulomb threshold are unstable to tangential perturbations and thus contribute to failure at the microscopic level. How is such a local property related to global f…
