Baryonic Post-Processing of N-body Simulations, with Application to Fast Radio Bursts
Ian Williams, Adnan Khan, Matthew McQuinn
Where the cosmic baryons lie in and around galactic dark matter halos is only weakly constrained. We develop a method to quickly paint on models for their distribution. Our approac…
The rheology of confined colloidal hard discs
Ian Williams, Erdal C. Oğuz, Hartmut Löwen +2
Colloids may be treated as `big atoms' so that they are good models for atomic and molecular systems. Colloidal hard disks are therefore good models for 2d materials and although t…
Simulations of Axion Minihalos
Huangyu Xiao, Ian Williams, Matthew McQuinn
The axion, motivated as a solution to the strong CP problem, is also a viable dark matter candidate. We use N-body simulations to study the formation of substructures from white-no…
Flexible confinement leads to multiple relaxation regimes in glassy colloidal liquids
Ian Williams, Erdal C. Oğuz, Paul Bartlettl +2
Understanding relaxation of supercooled fluids is a major challenge and confining such systems can lead to bewildering behaviour. Here we exploit an optically confined colloidal mo…
Transmission of torque at the nanoscale
Ian Williams, Erdal C. Oğuz, Thomas Speck +3
In macroscopic mechanical devices torque is transmitted through gearwheels and clutches. In the construction of devices at the nanoscale, torque and its transmission through soft m…
Experimental Determination of Configurational Entropy in a Two-Dimensional Liquid under Random Pinning
Ian Williams, Francesco Turci, James E. Hallett +4
A quasi two-dimensional colloidal suspension is studied under the influence of immobilisation (pinning) of a random fraction of its particles. We introduce a novel experimental met…
