Glassy polymers' strain-hardening moduli scale with their statistical-segment volumes

Robert S. Hoy

Using molecular dynamics simulations, we show that a widely-accepted theoretical prediction for glassy-polymeric strain hardening moduli ( $G_{R} \propto ρ_{e}$ , where $ρ_{e}$ is the enta…

Ultrastable jammed sphere packings with a wide range of particle dispersities

Robert S. Hoy

We show that for a standard continuously-polydisperse model with particle-diameter distribution $P (σ) \propto σ^{- 3}$ and polydispersity index $Δ$ , employing a combination of stand…

Quantitative relations between nearest-neighbor persistence and slow heterogeneous dynamics in supercooled liquids

Katrianna S. Sarkar, Kevin A. Interiano-Alberto, Jack F. Douglas +1

Using molecular dynamics simulations of a binary Lennard-Jones model of glass-forming liquids, we examine how the decay of the normalized neighbor-persistence function $C_{\rm B}(t…
