Local elastic perturbation of colloidal suspensions near the colloidal glass transition
Piotr Habdas, Rachel E. Courtland, Eric R. Weeks
Isolated microscopic magnetic particles are used to induce local perturbations in dense colloidal suspensions by rotating an external magnet. Confocal microscopy enables tracking o…
Correlations of Structure and Dynamics in an Aging Colloidal Glass
Gianguido C. Cianci, Rachel E. Courtland, Eric R. Weeks
We study concentrated colloidal suspensions, a model system which has a glass transition. Samples in the glassy state show aging, in that the motion of the colloidal particles slow…
Invariance of Structure in an Aging Colloidal Glass
Gianguido C. Cianci, Rachel E. Courtland, Eric R. Weeks
We study concentrated colloidal suspensions, a model system which has a glass transition. The non-equilibrium nature of the glassy state is most clearly highlighted by aging -- the…
Direct visualization of aging in colloidal glasses
Rachel E. Courtland, Eric R. Weeks
We use confocal microscopy to directly visualize the dynamics of aging colloidal glasses. We prepare a colloidal suspension at high density, a simple model system which shares many…
