Emergent medium-range order in amorphous silicon
Zhen Zhang, Stephen R. Elliott, Yujie Wang +1
Medium-range order (MRO) is an important feature of amorphous materials, but its nature in terms of atomic arrangement has remained elusive. Here, using large-scale machine-learnin…
Connecting heterogeneous dynamics with local entropy
Jun Wu, Walter Kob, Yujie Wang +1
Establishing a robust and physically interpretable link between static structure and heterogeneous relaxation dynamics remains a fundamental challenge in glass physics. Here, we in…
Symmetry Transitions Beyond the Nanoscale in Pressurized Silica Glass
Zhen Zhang, Zhencheng Xie, Walter Kob
Silica is the paradigmatic network glass-former and understanding its response to pressure is essential for comprehending the mechanical properties of silica-based materials and th…
Revealing hidden medium-range order in silicate glass-formers using many-body correlation functions
Zhen Zhang, Walter Kob
The medium range order (MRO) in amorphous systems has been linked to complex features such as the dynamic heterogeneity of supercooled liquids or the plastic deformation of glasses…
