Decoupling between thermodynamics and dynamics during rejuvenation in colloidal glasses

Xiunan Yang, Hua Tong, Weihua Wang +1

We rejuvenate well-aged quasi-2D binary colloidal glasses by thermal cycling, and systematically measure both the statistical responses and particle-level structural evolutions dur…

Possible origin of $β$ -relaxation in amorphous metal alloys from atomic-mass differences of the constituents

Bingyu Cui, Zach Evenson, Beibei Fan +3

We employ an atomic-scale theory within the framework of nonaffine lattice dynamics to uncover the origin of the Johari-Goldstein (JG) $β$ -relaxation in metallic glasses (MGs). Com…

Stretched and compressed exponentials in the relaxation dynamics of a metallic glass-forming melt

Zhen Wei Wu, Walter Kob, Wei-Hua Wang +1

The relaxation dynamics of glass-forming systems shows a multitude of features that are absent in normal liquids, such as non-exponential relaxation and a strong temperature-depend…
