Emergent facilitation by random constraints in a facilitated random walk model of glass
Leo S. I. Lam, Hai-Yao Deng, Wei-Bing Zhang +6
The physics of glass has been a significant topic of interest for decades. Dynamical facilitation is widely believed to be an important characteristic of glassy dynamics, but the p…

Penetration of surface effects on structural relaxation and particle hops in glassy films
Qiang Zhai, Hai-Yao Deng, Xin-Yuan Gao +4
A free surface induces enhanced dynamics in glass formers. We study the dynamical enhancement of glassy films with a distinguishable-particle lattice model of glass free of elastic…

Distinguishable-particle Glassy Crystal: the simplest molecular model of glass
Leo S. I. Lam, Gautham Gopinath, Zichen Zhao +7
The nature of glassy dynamics and the glass transition are long-standing problems under active debate. In the presence of a structural disorder widely believed to be an essential c…
