Local Plastic Response and Slow Heterogeneous Dynamics of Supercooled Liquids
Local Plastic Response and Slow Heterogeneous Dynamics of Supercooled Liquids
We demonstrate, via numerical simulations, that the relaxation dynamics of supercooled liquids correlates well with a plastic length scale measuring a particle's response to impulsive localized perturbations and weakly to measures of local elasticity. We find that the particle averaged plastic length scale vanishes linearly in temperature and controls the …
