Chiral structures and defects of lyotropic chromonic liquid crystals induced by saddle-splay elasticity
Zoey S. Davidson, Louis Kang, Joonwoo Jeong +4
An experimental and theoretical study of lyotropic chromonic liquid crystals (LCLCs) confined in cylinders with degenerate planar boundary conditions elucidates LCLC director confi…
Strain fluctuations and elastic moduli in disordered solids
Daniel M. Sussman, Samuel S. Schoenholz, Ye Xu +3
Recently there has been a surge in interest in using video-microscopy techniques to infer the local mechanical properties of disordered solids. One common approach is to minimize t…
Diagnosing hyperuniformity in two-dimensional disordered jammed-packings of soft spheres
Remi Dreyfus, Ye Xu, Tim Still +3
Hyperuniformity characterizes a state of matter for which density fluctuations diminish towards zero at the largest length scales. However, the task of determining whether or not a…
Colloidal Shape Effects in Evaporating Drops
Peter J. Yunker, Tim Still, A. G. Yodh
We explore the influence of particle shape on the behavior of evaporating drops. A first set of experiments discovered that particle shape modifies particle deposition after drying…
Phonon Dispersion and Elastic Moduli of Two-Dimensional Disordered Colloidal Packings of Soft Particles with Frictional Interactions
Tim Still, Carl P. Goodrich, Ke Chen +4
Particle tracking and displacement covariance matrix techniques are employed to investigate the phonon dispersion relations of two-dimensional colloidal glasses composed of soft, t…
Phonons in two-dimensional soft colloidal crystals
Ke Chen, Tim Still, Samuel Schoenholz +5
The vibrational modes of pristine and polycrystalline monolayer colloidal crystals composed of thermosensitive microgel particles are measured using video microscopy and covariance…
Effects of Particle Shape on Growth Dynamics at Edges of Evaporating Colloidal Drops
Peter J. Yunker, Matthew A. Lohr, Tim Still +3
We study the influence of particle shape on growth processes at the edges of evaporating drops. Aqueous suspensions of colloidal particles evaporate on glass slides, and convective…
Measurement of correlations between low-frequency vibrational modes and particle rearrangements in quasi-two-dimensional colloidal glasses
K. Chen, M. L. Manning, P. J. Yunker +4
We investigate correlations between low-frequency vibrational modes and rearrangements in two-dimensional colloidal glasses composed of thermosensitive microgel particles which rea…
Low-frequency vibrations of soft colloidal glasses
Ke Chen, Wouter G. Ellenbroek, Zexin Zhang +8
We conduct experiments on two-dimensional packings of colloidal thermosensitive hydrogel particles whose packing fraction can be tuned above the jamming transition by varying the t…
