Rotational and Translational Phonon Modes in Glasses Composed of Ellipsoidal Particles
Peter J. Yunker, Ke Chen, Zexin Zhang +3
The effects of particle shape on the vibrational properties of colloidal glasses are studied experimentally. 'Ellipsoidal glasses' are created by stretching polystyrene spheres to…
Helical Packings and Phase Transformations of Soft Spheres in Cylinders
Matthew A. Lohr, Ahmed M. Alsayed, Bryan G. Chen +3
The phase behavior of helical packings of thermoresponsive microspheres inside glass capillaries is studied as a function of volume fraction. Stable packings with long-range orient…
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…
