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…
Complexity Scaling of Liquid Dynamics
Ian M. Douglass, Jeppe C. Dyre, Lorenzo Costigliola
According to excess-entropy scaling, dynamic properties of liquids like viscosity and diffusion coefficient are determined by the entropy. This link between dynamics and thermodyna…
Distance-as-time in physical aging
Ian M. Douglass, Jeppe C. Dyre
Although it has been known for half a century that the physical aging of glasses in experiments is described well by a linear thermal-history convolution integral over the so-calle…
How a Supercooled Liquid Borrows Structure from the Crystal
Ulf Pedersen, Ian Douglass, Peter Harrowell
Using computer simulations, we establish that the structure of a supercooled binary atomic liquid mixture consists of common neighbour structures similar to those found in the equi…
The Formation of Ultra-Stable Glasses via Precipitation: a Modelling Study
Ian Douglass, Peter Harrowell
The precipitation of a glass forming solute from solution is modelled using a lattice model previously introduced to study dissolution kinetics of amorphous materials. The model in…
Assessing the Utility of Structure in Amorphous Materials
Dan Wei, Jie Yang, Min-Qiang Jiang +5
This paper presents a set of general strategies for the analysis of structure in amorphous materials and a general approach to assessing the utility of a selected structural descri…
The Kinetics of Dissolution of an Amorphous Solid
Ian Douglass, Peter Harrowell
The kinetics of dissolution of an amorphous solid is studied using a simple model of a glass that captures with reasonable accuracy the dynamic heterogeneities associated with the…
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…
Density and Glass Forming Ability in Amorphous Atomic Alloys: the Role of the Particle Softness
Ian Douglass, Toby Hudson, Peter Harrowell
A key property of glass forming alloys, the anomalously small volume difference with respect to the crystal, is shown to arise as a direct consequence of the soft repulsive potenti…
