Disentangling hierarchical relaxations in glass formers via dynamic eigenmodes
Wensi Sun, Yanshuang Chen, Wencheng Ji +6
Hierarchical dynamics in glass-forming systems span multiple timescales, from fast vibrations to slow structural rearrangements, appearing in both supercooled fluids and glassy sta…

The Role of Excitations in Supercooled Liquids: Density, Geometry, and Relaxation Dynamics
Wencheng Ji, Massimo Pica Ciamarra, Matthieu Wyart
Low-energy excitations play a key role in all condensed-matter systems, yet there is limited understanding of their nature in glasses, where they correspond to local rearrangements…
