Emergent collective motion of self-propelled condensate droplets

Kavli Affiliate: Joanna Aizenberg | First 5 Authors: Marcus Lin, Philseok Kim, Sankara Arunachalam, Rifan Hardian, Solomon Adera | Summary: Recently, there is much interest in droplet condensation on soft or liquid/liquid-like substrates. Droplets can deform soft and liquid interfaces resulting in a wealth of phenomena not observed on hard, solid surfaces (e.g., increased nucleation, […]

Entanglement transition in rod packings

Kavli Affiliate: L. Mahadevan | First 5 Authors: Yeonsu Jung, Thomas Plumb-Reyes, Hao-Yu Greg Lin, L. Mahadevan, | Summary: Random packings of stiff rods are self-supporting mechanical structures stabilized by their geometrical and topological complexity. To understand why, we deploy X-ray computerized tomography to unveil the structure of the packing. This allows us to define […]

Geometric frustration of hard-disk packings on cones

Kavli Affiliate: Vinothan N. Manoharan | First 5 Authors: Jessica H. Sun, Abigail Plummer, Grace H. Zhang, David R. Nelson, Vinothan N. Manoharan | Summary: Conical surfaces pose an interesting challenge to crystal growth: a crystal growing on a cone can wrap around and meet itself at different radii. We use a disk-packing algorithm to […]

Approximate Lie symmetries and singular perturbation theory

Kavli Affiliate: L. Mahadevan | First 5 Authors: Alexander J. Dear, L. Mahadevan, , , | Summary: Perturbation theory plays a central role in the approximate solution of nonlinear differential equations. The resultant series expansions are usually divergent and require treatment by singular perturbation methods to generate uniformly valid solutions. However, applying these methods is […]
