Boundary effects in a quasi-two-dimensional driven granular fluid (2017)
Journal Article

The effect of a confining boundary on the spatial variations in granular temperature of a driven quasi-2d layer of particles is investigated experimentally. The radial drop in the relative granular temperature ?T/T, exhibits a maximum at intermediate... Read More about Boundary effects in a quasi-two-dimensional driven granular fluid.

Optical detection and spatial modulation of mid-infrared surface plasmon polaritons in a highly doped semiconductor (2017)
Journal Article

Highly doped semiconductors (HDSCs) are promising candidates for plasmonic applications in the mid-infrared (MIR) spectral range. This work examines a recent addition to the HDSC family, the dilute nitride alloy In(AsN). Post-growth hydrogenation of...

Gravity in the quantum lab (2017)
Journal Article

At the beginning of the previous century, Newtonian mechanics was advanced by two new revolutionary theories, Quantum Mechanics (QM) and General Relativity (GR). Both theories have transformed our view of physical phenomena, with QM accurately predic... Read More about Gravity in the quantum lab.

Gravitational mechanisms to self-tune the cosmological constant: obstructions and ways forward (2017)
Journal Article

Gravitational models of self-tuning are those in which vacuum energy has no observable effect on spacetime curvature, even though it is a priori unsuppressed below the cut-off. We complement Weinberg's no go theorem by studying field theoretic comple... Read More about Gravitational mechanisms to self-tune the cosmological constant: obstructions and ways forward.

Phonon spectroscopy with chirped shear and compressive acoustic pulses (2017)
Journal Article

Picosecond duration compressive and shear phonon wave packets injected into (311) GaAs slabs transform after propagation through ?1??mm into chirped acoustic pulses with a frequency increasing in time due to phonon dispersion. By probing the temporal... Read More about Phonon spectroscopy with chirped shear and compressive acoustic pulses.

Neural circuitry underlying sustained attention in healthy adolescents and in ADHD symptomatology (2017)
Journal Article

Moment-to-moment reaction time variability on tasks of attention, often quantified by intra-individual response variability (IRV), provides a good indication of the degree to which an individual is vulnerable to lapses in sustained attention. Increa... Read More about Neural circuitry underlying sustained attention in healthy adolescents and in ADHD symptomatology.

Noise switching at a dynamical critical point in a cavity-conductor hybrid (2017)
Journal Article

Coupling a mesoscopic conductor to a microwave cavity can lead to fascinating feedback effects which generate strong correlations between the dynamics of photons and charges. We explore the connection between cavity dynamics and charge transport in... Read More about Noise switching at a dynamical critical point in a cavity-conductor hybrid.

The Herschel–ATLAS data release 2, Paper I. Submillimeter and far-infrared images of the South and North Galactic Poles: the largest Herschel survey of the extragalactic sky (2017)
Journal Article

We present the largest submillimeter images that have been made of the extragalactic sky. The Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS) is a survey of 660 deg2 with the PACS and SPIRE cameras in five photometric bands: 100, 160, 25...

Follow Up of GW170817 and Its Electromagnetic Counterpart by Australian-Led Observing Programmes (2017)
Journal Article

The discovery of the first electromagnetic counterpart to a gravitational wave signal has generated follow-up observations by over 50 facilities world-wide, ushering in the new era of multi-messenger astronomy. In this paper, we present follow-up obs... Read More about Follow Up of GW170817 and Its Electromagnetic Counterpart by Australian-Led Observing Programmes.

Cosmic CARNage I: on the calibration of galaxy formation models (2017)
Journal Article

We present a comparison of nine galaxy formation models, eight semi-analytical, and one halo occupation distribution model, run on the same underlying cold dark matter simulation (cosmological box of comoving width 125h−1 Mpc, with a dark-matter part...
