A quantitative theoretical model of the boson peak based on stringlet excitations
Cunyuan Jiang, Matteo Baggioli, Jack F. Douglas
The boson peak (BP), a low-energy excess in the vibrational density of states over the phonon Debye contribution, is usually identified as one of the distinguishing features betwee…
Parallel Emergence of Rigidity and Collective Motion in a Family of Simulated Glass-Forming Polymer Fluids
Xiaolei Xu, Jack F. Douglas, Wen-Sheng Xu
The emergence of the solid state in glass-forming materials upon cooling is accompanied by changes in both thermodynamic and viscoelastic properties and by a precipitous drop in fl…
Approach to Hyperuniformity in a Metallic Glass-Forming Material Exhibiting a Fragile to Strong Glass Transition
Hao Zhang, Xinyi Wang, Jiarui Zhang +2
We investigate a metallic glass-forming (GF) material (Al90Sm10) exhibiting a fragile-strong (FS) glass-formation by molecular dynamics simulation to better understand this highly…
Thermodynamic-Dynamic Interrelations in Glass-Forming Polymer Fluids
Xiaolei Xu, Jack F. Douglas, Wen-Sheng Xu
We utilize the lattice cluster theory (LCT) of polymer fluids to show that the configurational entropy, enthalpy, and internal energy are all closely interrelated, as suggested by…
The Initiation of Shear Band Formation in Deformed Metallic Glasses from Soft Localized Domains
Xinyi Wang, Hao Zhang, Jack F. Douglas
It has long been thought that shear band (SB) formation in amorphous solids initiates from relatively 'soft' regions in the material in which large-scale non-affine deformations be…
Equation of State and Entropy Theory Approach to Thermodynamic Scaling in Polymeric Glass-Forming Liquids
Jack F. Douglas, Wen-Sheng Xu
We show that thermodynamic scaling can be derived by combining the Murnaghan equation of state (EOS) with the generalized entropy theory (GET) of glass formation. In our theory, th…
