Title: Local Structural Fluctuations in a Supercooled Liquid

Abstract

The local structural properties of a supercooled metallic liquid system are examined using molecular dynamics simulations. These local properties include pressure, bulk modulus, shear modulus, volume strain and shear stress. We find two-step changes in the hydrodynamic diameter relating the diffusion to the shear viscosity in the Stokes-Einstein relation. They are closely correlated with the change in behavior of the structural fluctuations and the radial distribution function. We relate these changes with freezing of local shear and density fluctuations.
