Science / Technology - Colloquium

Soft matter is neither simple liquid nor crystalline solid, but in an in-between state, including bio materials, lipid membranes, liquid crystals, and colloidal suspensions. We are in fact familiar with soft matter from every-day life - paints, cheese, foams, or liquid crystal display - and are also made of soft matter. In contrast to hard condensed matter, soft matter is easily perturbed by a small stress, which also affects its dynamics and mechanical properties. I will discuss our recent findings on the perturbed dynamics of two soft materials; a colloidal glass and a gel. We find that diffusive behavior of colloidal particles is recovered by application of perturbation to a glassy system. These model systems may provide a valuable insight to the biological systems.
