- Structural 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 regions in the system. We have used normal mode analysis
to understand the origin of the rearranging regions. The low-frequency modes, obtained over short time scales, show strong
spatial correlation with the rearrangements that happen on long time scales.
