Soft Matter

Our group is interested in the physical properties of polymers, jammed and amorphous solids, colloids, granular materials, complex fluids, emulsions, and disordered systems.   Our mutual interests with the Statistical and Nonlinear Physics Group include nonlinear dynamics, fluid mechanics, jamming, stress-focussing, glass transitions, and fracture, while our mutual interests with the Condensed Matter and Optics group include cooperative magnetic phenomena and interface/surface effects in polymer films. We try to have frequent joint group meetings, to help facilitate collaboration and interaction between the theory and experimental work. If you are interested in attending these meetings, email Eric Weeks ( to be put on the email list.
