“…Commonly, such dynamics is separated into two contributions: transitions between ISs and vibrational motion into each energy basin of a given IS [1,7,8]. In other words, the dynamics is separated into short times (vibrations and transitions to minima separated by very low energy barriers) and long times [2,[12][13][14] (relaxation due to transitions into ISs), as was tested by Schroder et al [10] and Broderix et al [15]. Furthermore, the long-time dynamics in low-temperature model supercooled liquids has been found to be related with a hierarchy in the ISs, since it is possible to cluster them in metabasins (MB) [16][17][18][19][20], a feature that is reminiscent of the funnel structure of the energy landscape in proteins.…”
