Jamming on deformable surfaces
Zhaoyu Xie, Timothy J Atherton
Jamming is a fundamental transition that governs the mechanical behavior of particulate media, including sand, foam and dense suspensions but also biological tissues: Upon compress…
Structural Landscapes in Geometrically Frustrated Smectics
Jingmin Xia, Scott MacLachlan, Timothy J. Atherton +1
A phenomenological free energy model is proposed to describe the behavior of smectic liquid crystals, an intermediate phase that exhibits orientational order and layering at the mo…
Elongation and percolation of defect motifs in anisotropic packing problems
Zhaoyu Xie, Timothy J. Atherton
We examine the regime between crystalline and amorphous packings of anisotropic objects on surfaces of different genus by continuously varying their size distribution or shape from…
Geometry and kinetics determine the microstructure in arrested coalescence of Pickering emulsion droplets
Zhaoyu Xie, Christopher J. Burke, Badel Mbanga +2
An important strategy to stabilize emulsions is to arrest coalescence of the constituent droplets with an opposing rheological force. Colloidal particles adsorbed on the surface of…
Arrested coalescence of viscoelastic droplets: Ellipsoid shape effects and restructuring
Chen Hao, Zhaoyu Xie, Timothy J. Atherton +1
The stable configurations formed by two viscoelastic, ellipsoid-shaped droplets during their arrested coalescence has been investigated using micromanipulation experiments. Ellipso…
LGBT+ Inclusivity in Physics and Astronomy: A Best Practices Guide
Nicole Ackerman, Timothy Atherton, Adrian Ray Avalani +5
We present the second edition of a Best Practices Guide for academic departments and other institutions striving to create more inclusive environments for physicists and astronomer…
