P8.16Thu 811:<strong>10</strong>-14:00Connecting structural relaxation with the low frequencymodes in a hard-sphere colloidal glassAntina Ghosh, 1 Vijayakumar Chikkadi, 1 Peter Schall, 1 and Daniel Bonn 11 University of Amsterdam, Science Park 904, <strong>10</strong>98 XH, Amsterdam, NetherlandsStructural relaxation in hard-sphere colloidal glasses has been studied using confocal microscopy.The motion of individual particles is followed over long time scales to detect the rearranging regionsin the system. We have used normal mode analysis to understand the origin of the rearrangingregions. The low frequency modes, obtained over short time scales, show strong spatial correlationwith the rearrangements that happen on long time scales.16
