Spatial Dimensionality Dependence of Heterogeneity, Breakdown of the Stokes–Einstein Relation, and Fragility of a Model Glass-Forming Liquid

We investigate the heterogeneity of dynamics, breakdown Stokes–Einstein relation and fragility in a model glass forming liquid, binary mixture soft spheres with harmonic interaction potential for spatial dimensions from 3 to 8. The dynamical is quantified through susceptibility χ4 non-Gaussian parameter α2. find that fragility, degree relation, dynamics decrease increasing dimensionality. briefly describe dependence on density use it resolve an apparent inconsistency previous results.
