Two-stage Slowdown of Vacancy-mediated Diffusion in a Lattice Gas Model with Quenched Disorder and Spins
The study examines vacancy-mediated diffusion in a lattice gas model with random interactions and quenched spins to understand hierarchical dynamics in glassy systems. The research found a two-stage slowdown in particle movement, attributing it to anti-correlations at different spatial and temporal scales. This suggests normal diffusion occurs only at very large time limits.
