Long Range Stress Correlations in the Inherent Structures of Liquids at Rest
Sadrul Chowdhury, Sneha Abraham, Toby Hudson +1
Simulation studies of the atomic shear stress in the local potential energy minima (inherent structures) are reported for binary liquid mixtures in 2D and 3D. These inherent struct…
Non-Affine Displacements and the Non-Linear Response of a Strained Amorphous Solid
Shibu Saw, Sneha Abraham, Peter Harrowell
We demonstrate that irreversible structural reorganization is not necessary for the observation of yield behaviour in an amorphous solid. While the majority of solids strained to t…
The Origin of Persistent Shear Stress in Supercooled Liquids
Sneha Abraham, Peter Harrowell
We show that the long time tail of the shear stress autocorrelation, whose growth at large supercooling is responsible for the apparent divergence of the shear viscosity, is a dire…
Vibrational dynamics and boson peak in a supercooled polydisperse liquid
Sneha Elizabeth Abraham, Biman Bagchi
Vibrational density of states (VDOS) in a supercooled polydisperse liquid is computed by diagonalizing the Hessian matrix evaluated at the potential energy minima for systems with…
Suppression of the rate of growth of dynamic heterogeneities and its relation to the local structure in a supercooled polydisperse liquid
Sneha Elizabeth Abraham, Biman Bagchi
The relationship between the microscopic arrangement of molecules in a supercooled liquid and its slow dynamics at low temperature near glass transition is studied by Molecular Dyn…
Energy Landscape, Anti-Plasticization and Polydispersity Induced Crossover of Heterogeneity in Supercooled Polydisperse Liquids
Sneha Elizabeth Abraham, Sarika Maitra Bhattacharrya, Biman Bagchi
Polydispersity is found to have a significant effect on the potential energy landscape; the the average inherent structure energy with temperature decreases with polydispersity. In…
