The School of Physics & Astronomy is one of the leading Physics departments in the UK, carrying out research in a broad range of areas such as Astronomy, Cosmology, Particle Physics, Nuclear Physics, Condensed Matter Physics, Biophysics and Astrobiology.

Researchers in the School are regularly involved in high-impact work such as the search for the Higgs Boson, the study of the oldest galaxies in the Universe, and investigating the nature of the "dark matter" and "dark energy", which make up 95% of the universe.

The School's research varies from being highly fundamental to very applied and a number of our research groups are involved in collaborative projects with industrial partners.

• #### Data accompanying "Shaping the Growth Behaviour of Biofilms Initiated from Bacterial Aggregates, 2013-2016" (Submitted paper). ﻿

Bacterial biofilms are usually assumed to originate from individual cells deposited on a surface. However, many biofilm-forming bacteria tend to aggregate in the planktonic phase so that it is possible that many natural ...
• #### A 1-dimensional statistical mechanics model for nucleosome positioning on genomic DNA ﻿

The first level of folding of DNA in eukaryotes is provided by the so-called “10-nm chromatin fibre”, where DNA wraps around histone proteins (∼10 nm in size) to form nucleosomes, which go on to create a zig-zagging ...
• #### Lid-driven cavity flow of viscoelastic liquids ﻿

The lid-driven cavity flow is a well-known benchmark problem for the validation of new numerical methods and techniques. In experimental and numerical studies with viscoelastic fluids in such lid-driven flows, purely-elastic ...
• #### What is the ‘minimum inhibitory concentration’ (MIC) of pexiganan acting on Escherichia coli? - A cautionary case study ﻿

We measured the minimum inhibitory concentration (MIC) of the antimicrobial peptide pexiganan acting on Escherichia coli, and report an intrinsic variability in such measurements. These results led to a detailed study of ...
• #### Predicting the three-dimensional folding of cis-regulatory regions in mammalian genomes using bioinformatic data and polymer models ﻿

The three-dimensional organisation of chromosomes can be probed using methods such as Capture-C. However it is unclear how such population level data relates to the organisation within a single cell, and the mechanisms ...
• #### Pressure-induced localisation of the hydrogen-bond network in KOH-VI ﻿

Using a combination of ab initio crystal structure prediction and neutron diffraction techniques, we have solved the full structure of KOH-VI at 7 GPa. Rather than being orthorhombic and proton-ordered as had previously ...
• #### Computational phase diagrams of noble gas hydrates under pressure ﻿

We present results from a first-principles study on the stability of noble gas-water compounds in the pressure range 0-100 kbar. Filled-ice structures based on the host water networks ice-Ih, ice-Ic, ice-II, and C0 interacting ...
• #### Theory of high pressure hydrogen, made simple / AIRAPT 2015 data ﻿

We report molecular dynamics calculations for Phase I of hydrogen which show that all the phase transitions can be understood in a classical model with simple treatment of exchange-correlation. We present code for a simple ...
• #### Two-scale evolution during shear reversal in dense suspensions ﻿

Matlab data files used to plot the figures in a paper titled "Two-scale evolution during shear reversal in dense suspensions".
• #### Shear thickening regimes of dense non-Brownian suspensions ﻿

The images are the raw figures used to produce the plots in the paper entitled: “Shear thickening regimes of dense non-Brownian suspensions” with DOI:10.1039/C5SM02326B published in the Journal “Soft Matter” by the Royal ...
• #### Hydrodynamic and Contact Contributions to Continuous Shear Thickening in Colloidal Suspensions ﻿

Shear thickening is a widespread phenomenon in suspension flow that, despite sustained study, is still the subject of much debate. The longstanding view that shear thickening is due to hydrodynamic clusters has been ...
• #### Simplicity in complexity – towards a soft matter physics of caramel ﻿

Caramel is a mixture of sugars, milk proteins, fat and water cooked at high temperatures to initiate Maillard reactions. We study caramels as ‘active emulsion-filled protein gels’, in which fat droplets are chemically-bonded ...
• #### Gravitational collapse of depletion-induced colloidal gels ﻿

We study the ageing and ultimate gravitational collapse of gel states in hard-sphere-like colloids in which an interparticle depletion attraction has been induced by non-adsorbing polymers. Visual observations show that ...
• #### Swimming In a Crystal ﻿

We study catalytic Janus particles and Escherichia coli bacteria swimming in a two-dimensional colloidal crystal. The Janus particles orbit individual colloids and hop between colloids stochastically, with a hopping rate ...
• #### Sudden relaminarisation and lifetimes in forced isotropic turbulence ﻿

We demonstrate an unexpected connection between isotropic turbulence and wall-bounded shear flows. We perform direct numerical simulations of isotropic turbulence forced at large scales at moderate Reynolds numbers and ...
• #### Particle-size effects in the formation of bicontinuous Pickering emulsions ﻿

We demonstrate that the formation of bicontinuous emulsions stabilized by interfacial particles (bijels) is more robust when nanoparticles rather than microparticles are used. Emulsification via spinodal demixing in the ...

• #### Escherichia coli as a model active colloid: A practical introduction ﻿

The ﬂagellated bacterium Escherichia coli is increasingly used experimentally as a self-propelled swimmer. To obtain meaningful, quantitative results that are comparable between different laboratories, reproducible protocols ...
• #### Towards a unified description of the rheology of hard-particle suspensions ﻿

The rheology of suspensions of Brownian, or colloidal, particles (diameter~$d \lesssim 1~\mu$m) differs markedly from that of larger grains ($d \gtrsim 50~\mu$m). Each of these two regimes has been separately studied, but ...
