Role of length and time scales of dynamic heterogeneities on fragility in various model glasses


Kang Kim (Niigata University)


We report simulation results for various models of glass-forming liquids such as binary KobAndersen, Wahnstrom, soft-sphere, and Coslovich-Pastore network-forming liquids. While the first three models act as fragile liquids exhibiting super-Arrhenius temperature dependence in their relaxation times, the last is a strong glass-former exhibiting Arrhenius behavior. In the presentation, the role of dynamic heterogeneities on the fragility will be investigated from the perspectives of the length and time scales that are quantified from multi-point and multi-time correlation functions.
