Evidence for marginal stability in emulsions
Jie Lin, Ivane Jorjadze, Lea-Laetitia Pontani +2
We report the first measurements of the effect of pressure on vibrational modes in emulsions, which serve as a model for soft frictionless spheres at zero temperature. As a functio…
A microscopic approach to the nonlinear elasticity of compressed emulsions
Ivane Jorjadze, Lea-Laetitia Pontani, Jasna Brujic
Using confocal microscopy, we measure the packing geometry and interdroplet forces as a function of the osmotic pressure in a 3D emulsion system. We find that the nonlinear elastic…
A granocentric model captures the statistical properties of monodisperse random packings
Katherine A. Newhall, Ivane Jorjadze, Eric Vanden-Eijnden +1
We present a generalization of the granocentric model proposed in [Clusel et al., Nature, 2009, 460, 611615] that is capable of describing the local fluctuations inside not only po…
Biomimetic emulsions reveal the effect of homeostatic pressure on cell-cell adhesion
Lea-Laetitia Pontani, Ivane Jorjadze, Virgile Viasnoff +1
Cell-cell contacts in tissues are continuously subject to mechanical forces due to homeostatic pressure and active cytoskeleton dynamics. While much is known about the molecular pa…
Jamming phase diagram of athermal emulsions with short-range attraction
Ivane Jorjadze, Lea-Laetitia Pontani, Katherine Newhall +1
Using confocal microscopy we investigate the effect of attraction on the packing of polydisperse emulsions under gravity. We find that the distributions of neighbors, coordination…
