Dynamical Theory of the Inverted Cheerios Effect
Anupam Pandey, Stefan Karpitschka, Luuk A. Lubbers +5
Recent experiments have shown that liquid drops on highly deformable substrates exhibit mutual interactions. This is similar to the Cheerios effect, the capillary interaction of so…
Mixing by Unstirring: Hyperuniform Dispersion of Interacting Particles upon Chaotic Advection
Joost H. Weijs, Denis Bartolo
We show how to achieve both fast and hyperuniform dispersions of particles in viscous fluids. To do so, we first extend the concept of critical random organization to chaotic drive…
Emergent hyperuniformity in periodically-driven emulsions
Joost H. Weijs, Raphaël Jeanneret, Rémi Dreyfus +1
We report the emergence of large-scale hyperuniformity in microfluidic emulsions. Upon periodic driving confined emulsions undergo a first-order transition from a reversible to an…
Capillarity of soft amorphous solids: a microscopic model for surface stress
Joost H. Weijs, Jacco H. Snoeijer, Bruno Andreotti
The elastic deformation of a soft solid induced by capillary forces crucially relies on the excess stress inside the solid-liquid interface. While for a liquid-liquid interface thi…
Elasto-capillarity at the nanoscale: on the coupling between elasticity and surface energy in soft solids
Joost H. Weijs, Bruno Andreotti, Jacco H. Snoeijer
The capillary forces exerted by liquid drops and bubbles on a soft solid are directly measured using molecular dynamics simulations. The force on the solid by the liquid near the c…
Suppression and emergence of granular segregation under cyclic shear
Matt Harrington, Joost H. Weijs, Wolfgang Losert
While convective flows are implicated in many granular segregation processes, the associated particle-scale rearrangements are not well understood. A three-dimensional bidisperse m…
