Direction-dependent Dynamics of Colloidal Particle Pairs and the Stokes-Einstein Relation in Quasi-Two-Dimensional Fluids

Autor: Barbhuiya, Noman Hanif, Yodh, A. G., Mishra, Chandan K.

Hydrodynamic interactions are important for diverse fluids especially those with low Reynold's number such as microbial and particle-laden suspensions, and proteins diffusing in membranes. Unfortunately, while far-field (asymptotic) hydrodynamic inte

Scaling of relaxation and excess entropy in plastically deformed amorphous solids

Autor: Galloway, K. L., Ma, Xiaoguang, Keim, Nathan C., Jerolmack, Douglas J., Yodh, Arjun G., Arratia, Paulo E.

When stressed sufficiently, solid materials yield and deform plastically via reorganization of microscopic constituents. Indeed, it is possible to alter the micro-structure of materials by judicious application of stress, an empirical pro- cess utili

Relationships among structure, memory, and flow in sheared disordered materials

Autor: Galloway, K. L., Teich, E. G., Ma, X-g, Kammer, Ch., Graham, I. R., Keim, N. C., Reina, C., Jerolmack, D. J., Yodh, A. G., Arratia, P. E.

A fundamental challenge for disordered solids is predicting macroscopic yield from the microscopic arrangements of constituent particles. Yield is accompanied by a sudden and large increase in energy dissipation due to the onset of plastic rearrangem
