Figure 1

IS (solid line) and metabasins (dotted line) visited during the course of a 70 particle molecular dynamics run at $T^{*}=0.49$. The dotted line is slightly shifted along the energy axis for better clarity. IS transitions within a metabasin are denoted $\beta$ while transitions from one metabasin to another are denoted $\alpha$. The IS energies are divided by the total number of particles in the system. Typical motion of particles during the transitions depicted in (a). Pretransition particles are black, while post-transition particles are white. (b) Transition corresponding to $\beta$ relaxation. Only movement greater than $0.08{\sigma }_{AA}$ is shown. (c) Transition corresponding to $\alpha$ relaxation. Particle movement greater than $0.3{\sigma }_{AA}$ is shown.Reuse & Permissions

(a) Probability distribution of metabasin energies per particle [$P(E_{MB},T)$] for $T^{*}=0.490$, 0.575, 0.669, and 0.764 (from left to right). The solid lines are the Gaussian fits for the corresponding temperature. (b) Distribution of hopping times from metabasins in a 70 particle system for $T^{*}=0.764$, 0.669, 0.575, and 0.490 (from left to right). Values of $\Delta$ obtained from fits are 1.84, 2.40, 2.80, and 3.13, respectively. The curves are shifted in time to fit inside the figure.Reuse & Permissions

Figure 3

Correlation function $C(t)$ as defined in the text. Arrows point to the axis for which a given fit (power law or stretched exponential) should yield a straight line. The data clearly support the stretched exponential fit over the power law fit. The solid line is for $T^{*}=0.490$ and the dotted line is for $T^{*}=0.575$.Reuse & Permissions
