Journal Article
Chehade, B., Shanks, T., Findlay, J., Metcalfe, N., Sawangwit, U., Irwin, M., …Bielby, R. (2016). The 2QDES Pilot : The luminosity and redshift dependence of quasar clustering. Monthly Notices of the Royal Astronomical Society, 459(2), 1179-1200. https://doi.org/10.1093/mnras/stw616

We present a new redshift survey, the 2dF Quasar Dark Energy Survey pilot (2QDESp), which consists of ≈10 000 quasars from ≈150 deg2 of the southern sky, based on VST-ATLAS imaging and 2dF/AAOmega spectroscopy. Combining our optical photometry with t... Read More about The 2QDES Pilot : The luminosity and redshift dependence of quasar clustering.

In the quest to build a practical quantum computer, it is important to use efficient schemes for enacting the elementary quantum operations from which quantum computer programs are constructed. The opposing requirements of well-protected quantum data... Read More about Hybrid quantum computing with ancillas.

Tracking the energetics of the non-thermal disc–corona–jet in the very high state GX 339 − 4 (2016)
Journal Article

The dramatic hard–soft spectral transition in black hole binaries is important as it is associated with the collapse of the jet and with the strongest low-frequency quasi-periodic oscillations (QPOs). These transition spectra (intermediate and very h... Read More about Tracking the energetics of the non-thermal disc–corona–jet in the very high state GX 339 − 4.

Ternary Free Energy Lattice Boltzmann Model with Tunable Surface Tensions and Contact Angles (2016)
Journal Article

We present a ternary free-energy lattice Boltzmann model. The distinguishing feature of our model is that we are able to analytically derive and independently vary all fluid-fluid surface tensions and the solid surface contact angles. We carry out a...

We present the line-of-sight (LOS) velocities for 13 distant main sequence Milky Way halo stars with published proper motions. The proper motions were measured using long baseline (5-7 years) multi-epoch HST/ACS photometry, and the LOS velocities wer...

Enhanced optical cross section via collective coupling of atomic dipoles in a 2D array (2016)
Journal Article
Bettles, R. J., Gardiner, S. A., & Adams, C. S. (2016). Enhanced optical cross section via collective coupling of atomic dipoles in a 2D array. Physical Review Letters, 116(10), Article 103602. https://doi.org/10.1103/physrevlett.116.103602

Enhancing the optical cross section is an enticing goal in light-matter interactions, due to its fundamental role in quantum and nonlinear optics. Here, we show how dipolar interactions can suppress off-axis scattering in a two-dimensional atomic arr...

La2SrCr2O7F2: A Ruddlesden–Popper Oxyfluoride Containing Octahedrally Coordinated Cr4+ Centers (2016)
Journal Article

The low-temperature fluorination of the n = 2 Ruddlesden–Popper phase La2SrCr2O7 yields La2SrCr2O7F2 via a topochemical fluorine insertion reaction. The structure-conserving nature of the fluorination reaction means that the chromium centers of the i...

In a previous study Whitbourn & Shanks have reported evidence for a local void underdense by ≈15 per cent extending to 150–300 h−1 Mpc around our position in the Southern Galactic Cap (SGC). Assuming a local luminosity function they modelled K- and r... Read More about The galaxy luminosity function and the Local Hole.
