Lindemann unjamming of emulsions
Rodrigo E. Guerra
We study the bulk and shear elastic properties of barely-compressed, "athermal" emulsions and find that the rigidity of the jammed solid fails at remarkably large critical osmotic…
Hyperuniform structures formed by shearing colloidal suspensions
Sam Wilken, Rodrigo E. Guerra, David J. Pine +1
In periodically sheared suspensions there is a dynamical phase transition characterized by a critical strain amplitude between an absorbing state where particle trajectories…
Freezing on a Sphere
Rodrigo E. Guerra, Colm P. Kelleher, Andrew D. Hollingsworth +1
The best-understood crystal ordering transition is that of two-dimensional freezing, which proceeds by the rapid eradication of lattice defects as the temperature is lowered below…
Charged hydrophobic colloids at an oil/aqueous phase interface
Colm P. Kelleher, Anna Wang, Guillermo Iván Guerrero-García +6
Hydrophobic PMMA colloidal particles, when dispersed in oil with a relatively high dielectric constant, can become highly charged. In the presence of an interface with a conducting…
Phase behavior of charged colloids at a fluid interface
Colm P. Kelleher, Rodrigo E. Guerra, Andrew D. Hollingsworth +1
We study the phase behavior of a system of charged colloidal particles that are electrostatically bound to an almost flat interface between two fluids. We show that, despite the fa…
