30. The overall behavior of our experiment and model demonstrate also a more complex picture than what is normally presented in the theory of glasses: the global stretched-exponential dynamics is generated not from a sum of simple exponentials with varying time scale but from stretched-exponential distributions with β ranging from zero to one. This raises the possibility that the local dynamics in glasses could be more complex that what is described in the traditional heterogeneous model.
