String-like Rearrangements Induce Mobility in Supercooled Liquids
Rahul N. Chacko
Dynamical heterogeneity is a signature phenomenon of deeply supercooled liquids and glasses. Here, we demonstrate that the spatiotemporal correlations between local relaxation even…
Dynamical Facilitation Governs the Equilibration Dynamics of Glasses
Rahul N. Chacko, François P. Landes, Giulio Biroli +3
Convincing evidence of domain growth in the heating of ultrastable glasses suggests that the equilibration dynamics of super-cooled liquids could be driven by a nucleation and grow…
Elastoplasticity Mediates Dynamical Heterogeneity Below the Mode-Coupling Temperature
Rahul N. Chacko, François P. Landes, Giulio Biroli +3
As liquids approach the glass transition temperature, dynamical heterogeneity emerges as a crucial universal feature of their behavior. Dynamic facilitation, where local motion tri…
Slow coarsening in jammed athermal soft particle suspensions
Rahul N. Chacko, Peter Sollich, Suzanne M. Fielding
We simulate a densely jammed, athermal assembly of repulsive soft particles immersed in a solvent. Starting from an initial condition corresponding to a quench from a high temperat…
Dynamic vorticity banding in discontinuously shear thickening suspensions
Rahul N. Chacko, Romain Mari, Michael E. Cates +1
It has recently been argued that steady-state vorticity bands cannot arise in shear thickening suspensions, because the normal stress imbalance across the interface between the ban…
Shear Reversal in Dense Suspensions: The Challenge to Fabric Evolution Models from Simulation Data
Rahul N. Chacko, Romain Mari, Suzanne M. Fielding +1
Despite the industrial importance of dense suspensions of hard particles, few constitutive models for them have been proposed or tested. Most of these are effectively "fabric evolu…
