抄録

We study a highly supercooled two-dimensional fluid mixture via molecular dynamics simulation. We follow bond breakage events among particle pairs, which occur on the scale of the α relaxation time τ_α. Large scale heterogeneities analogous to the critical fluctuations in Ising systems are found in the spatial distribution of bonds which are broken in a time interval with a width of order 0.05τ_α. The structure factor of the broken bond density is well approximated by the Ornstein-Zernike form.The correlation length is of order 100 σ₁ at the lowest temperature studied, σ₁ being the particle size.The weakly bonded regions thus identified evolve in time with strong spatial correlations.
