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…

Stirring supercooled colloidal liquids at the particle scale
Piotr Habdas, Eric R. Weeks
We study the decay of tangential velocity profiles with distance from a local disturbance in hard-sphere colloidal suspensions as the colloidal glass transition is approached. The…
