Spatially heterogeneous dynamics during physical aging far below the glass transition temperature

Physical aging experiments after a deep quench were performed via an optical photobleaching technique to examine the evolution of the segmental dynamics of a polystyrene melt far below the glass transition temperature (Tg). Both rotational and translational diffusion measurements of dilute tetracene...
