Spatial Structures and Dynamics of Kinetically Constrained Models of Glasses
Spatial Structures and Dynamics of Kinetically Constrained Models of Glasses
Kob and Andersen's simple lattice models for the dynamics of structural glasses are analyzed. Although the particles have only hard core interactions, the imposed constraint that they cannot move if surrounded by too many others causes slow dynamics. On Bethe lattices, a dynamical transition to a partially frozen phase occurs. …
