What Lies Between Crystal and Randomly Packed Structures? A General Characterization of Non-Periodic Order

Ian Douglass, Peter Harrowell

In this paper we address the characterization of the structure of condensed materials, periodic and non-periodic. Carrying out an extensive study of over 7000 different groundstate…

Structural Diversity in Condensed Matter: A General Characterization of Crystals, Amorphous Solids and the Structures Between

Yueran Wang, Peter Harrowell

A definition of structural diversity, adapted from the biodiversity literature, is introduced to provide a general characterization of structures of condensed matter. Using the Fav…

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…

Translation-Rotation Coupling and the Kinematics of Non-Slip Boundary Conditions: A Rough Sphere between Two Sliding Walls

Yueran Wang, Peter Harrowell

A non-slip constraint between a particle and a wall is applied at the microscopic level of collision dynamics using the rough sphere model. We analyse the consequences of the trans…

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…

Crystal Growth Rates from Molecular Liquids: The Kinetics of Entropy Loss

Richard K Bowles, Peter Harrowell

It has been established empirically that the rate of addition of molecules to the crystal during crystal growth from the melt is proportional to exp(-|ΔS_fus|/R) where ΔS_fus is th…
