Inferring the flow properties of epithelial tissues from their geometry
Marko Popović, Valentin Druelle, Natalie A. Dye +2
Amorphous materials exhibit complex material proprteties with strongly nonlinear behaviors. Below a yield stress they behave as plastic solids, while they start to yield above a cr…
Thermal origin of quasi-localised excitations in glasses
Wencheng Ji, Tom W. J. de Geus, Marko Popović +2
Key aspects of glasses are controlled by the presence of excitations in which a group of particles can rearrange. Surprisingly, recent observations indicate that their density is d…
How collective asperity detachments nucleate slip at frictional interfaces
Tom W. J. de Geus, Marko Popović, Wencheng Ji +2
Sliding at a quasi-statically loaded frictional interface can occur via macroscopic slip events, which nucleate locally before propagating as rupture fronts very similar to fractur…
Theory for the density of interacting quasi-localised modes in amorphous solids
Wencheng Ji, Marko Popović, Tom W. J. de Geus +2
Quasi-localised modes appear in the vibrational spectrum of amorphous solids at low-frequency. Though never formalised, these modes are believed to have a close relationship with o…
