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…

Surface mobility gradient and emergent facilitation in glassy films
Qiang Zhai, Xin-Yuan Gao, Chun-Shing Lee +5
Confining glassy polymer into films can substantially modify their local and film-averaged properties. We present a lattice model of film geometry with void-mediated facilitation b…

The distinguishable-particle lattice model of glasses in three dimensions
Bo Li, Chun-Shing Lee, Xin-Yuan Gao +2
The nature of glassy states in realistic finite dimensions is still under fierce debate. Lattice models can offer valuable insights and facilitate deeper theoretical understanding.…
