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…
Anisotropic medium-range order uncovers dynamic crossovers in glass-forming liquids
Kamlesh Mishra, Rajesh Ganapathy, Walter Kob
On cooling liquids towards their glass-transition temperature, the dramatic increase of their relaxation times is accompanied by changes in particle dynamics at two distinct temper…
Effective particle size governs structure and dynamics in rough hard-particle fluids
Nanqing Xiao, Zhen Zhang, Walter Kob +1
We numerically investigate how particle surface roughness affects the static and dynamic properties of a hard-particle fluid across a wide range of densities, rho. These simulation…
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…
