The Structural Difference Between Strong and Fragile Liquids
Gang Sun, Peter Harrowell
A structural order parameter for disordered configurations is defined, based, not on local topologies, but on the degree of local restraint imposed on each atom. This restraint par…
Amorphous Solidification of a Supercooled Liquid in the Limit of Rapid Cooling
Gang Sun, Peter Harrowell
We monitor the transformation of a liquid into an amorphous solid in simulations of a glass forming liquid by measuring the variation of a structural order parameter with either ch…
A General Structural Order Parameter for the Amorphous Solidification of a Supercooled Liquid
Gang Sun, Peter Harrowell
The persistent problem posed by the glass transition is to develop a general atomic level description of a solidification process that is not associated with any change in the symm…
How Real are Liquid Groundstates? Ultra-Fast Crystal Growth and the Susceptibility of Energy Minima in Liquids
Gang Sun, Peter Harrowell
We calculate the degree to which the final structure of the local groundstate in a liquid is a function of the strength of a perturbing potential applied during energy minimization…
The Structural Origin of Enhanced Dynamics at the Surface of a Glassy Alloy
Gang Sun, Shibu Saw, Ian Douglass +1
The enhancement of mobility at the surface of an amorphous alloy is studied using a combination of molecular dynamic simulations and normal mode analysis of the non-uniform distrib…
