Title
The Statistics of Inherent Structure Stress in a Supercooled Liquid
Speaker
Peter Harrowell (University of Sydney)
Abstract
The existence of a distribution of shear stress associated with the local potential minima
(inherent structures) of a liquid provides the essential reason why stress relaxation must be activated
since this ‘inherent’ stress can only be relaxed through multiple transitions
about the energy landscape of the liquid.
We still know very little about the material factors
that determine the statistics of this inherent stress nor
how local particle rearrangements are translated into stress changes.
In this talk we present evidence that the total inherent stress
is the result of the sum of only weakly correlated individual particle stresses
and explore the connection between these stresses and the force network of the inherent structures.
The relationship between the variance of the inherent stress fluctuations
and the elastic modulus of a glass at non-zero temperatures is considered.
