Packing Concave Molecules in Crystals and Amorphous Solids: On the Connection between Shape and Local Structure
Cerridwen Jennings, Malcolm Ramsay, Toby Hudson +1
The structure of the densest crystal packings is determined for a variety of concave shapes in 2D constructed by the overlap of two or three disks. The maximum contact number per p…
Phase diagram of heteronuclear Janus dumbbells
Patrick O'Toole, Achille Giacometti, Toby Hudson
Using Aggregation-Volume-Bias Monte Carlo simulations along with Successive Umbrella Sampling and Histogram Re-weighting, we study the phase diagram of a system of dumbbells formed…
Long Range Stress Correlations in the Inherent Structures of Liquids at Rest
Sadrul Chowdhury, Sneha Abraham, Toby Hudson +1
Simulation studies of the atomic shear stress in the local potential energy minima (inherent structures) are reported for binary liquid mixtures in 2D and 3D. These inherent struct…
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…
Cluster formation and phase separation in heteronuclear Janus dumbbells
Gianmarco Munaò, Patrick O'Toole, Toby S. Hudson +4
We have recently investigated the phase behaviour of model colloidal dumbbells constituted by two identical tangent hard spheres, with the first one being surrounded by an attracti…
Self-assembly of hard helices: a rich and unconventional polymorphism
Hima Bindu Kolli, Elisa Frezza, Giorgio Cinacchi +5
Hard helices can be regarded as a paradigmatic elementary model for a number of natural and synthetic soft matter systems, all featuring the helix as their basic structural unit: f…
From rods to helices: evidence of a screw-like nematic phase
Hima Bindu Kolli, Elisa Frezza, Giorgio Cinacchi +3
Evidence of a special chiral nematic phase is provided using numerical simulation and Onsager theory for systems of hard helical particles. This phase appears at the high density e…
Crystallization of the Lewis-Wahnström ortho-terphenyl model
Ulf R. Pedersen, Toby S. Hudson, Peter Harrowell
Crystallization is observed during long molecular dynamics simulations of bent trimers, a molecular model proposed by Lewis and Wahnström for ortho-terphenyl. In the crystal, the t…
