Design of Quantum Dot-Nanowire Single-Photon Sources that are Immune to Thermomechanical Decoherence (2019)
Journal Article

Nanowire antennas embedding a single quantum dot (QD) have recently emerged as versatile platforms to realize bright sources of quantum light. In this theoretical work, we show that the thermally driven, low-frequency vibrations of the nanowire have...

Reduced Myelin Signal in Normal-appearing White Matter in Neuromyelitis Optica Measured by 7T Magnetic Resonance Imaging (2019)
Journal Article

Whether the integrity of normal-appearing white matter (NAWM) is preserved in neuromyelitis optica spectrum disorders (NMOSD) is open to debate. To examine whether the tissue integrity of NAWM in NMOSD is compromised compared to that in healthy contr...

The association between subcortical and cortical fMRI and lifetime noise exposure in listeners with normal hearing thresholds (2019)
Journal Article

© 2019 In animal models, exposure to high noise levels can cause permanent damage to hair-cell synapses (cochlear synaptopathy) for high-threshold auditory nerve fibers without affecting sensitivity to quiet sounds. This has been confirmed in several... Read More about The association between subcortical and cortical fMRI and lifetime noise exposure in listeners with normal hearing thresholds.

Quantum corrections to vacuum energy sequestering (with monodromy) (2019)
Journal Article

Field theory models of axion monodromy have been shown to exhibit vacuum energy sequestering as an emergent phenomenon for cancelling radiative corrections to the cosmological constant. We study one loop corrections to this class of models coming fro... Read More about Quantum corrections to vacuum energy sequestering (with monodromy).

From the outside looking in: what can Milky Way Analogues tell us about the star formation rate of our own galaxy? (2019)
Journal Article

The Milky Way has been described as an anaemic spiral, but is its star formation rate (SFR) unusually low when compared to its peers? To answer this question, we define a sample of Milky Way Analogues (MWAs) based on stringent cuts on the best litera...

High-Frequency Elastic Coupling at the Interface of van der Waals Nanolayers Imaged by Picosecond Ultrasonics (2019)
Journal Article

Although the topography of van de Waals (vdW) layers and heterostructures can be imaged by scanning probe microscopy, high-frequency interface elastic properties are more difficult to assess. These can influence the stability, reliability and perform... Read More about High-Frequency Elastic Coupling at the Interface of van der Waals Nanolayers Imaged by Picosecond Ultrasonics.

Accelerated relaxation and suppressed dynamic heterogeneity in a kinetically constrained (East) model with swaps (2019)
Journal Article

We introduce a kinetically constrained spin model with a local softness parameter, such that spin flips can violate the kinetic constraint with an (annealed) site-dependent rate. We show that adding MC swap moves to this model can dramatically accele...

AIRBED: a simpli?ed density functional theory model for physisorption on surfaces (2019)
Journal Article

Dispersion interactions are commonly included in density functional theory (DFT) calculations through the addition of an empirical correction. In this study, a modi?cation is made to the damping function in DFT-D2 calculations, to describe repulsion...

Journal Article

Time-slicing spiral galaxies with SDSS-IV MaNGA (2019)
Journal Article

Spectra of galaxies contain a wealth of information about the stellar populations from which they are made. With integral-field unit (IFU) surveys, such data can be used to map out stellar population properties across the face of a galaxy, allowing o...

The role of microstructural development in the hydrothermal corrosion of cast and HIPed Stellite 6 analogues in simulated PWR conditions (2019)
Journal Article

The corrosion behaviour of cast and HIPed Stellite 6 analogue materials in PWR-simulating conditions was investigated. The cast alloy exhibited localised corrosion at the boundary between the matrix and the M7C3 carbides, with this being attributed t...

Theory of double Cooper-pair tunneling and light emission mediated by a resonator (2019)
Journal Article

Photon emission by tunneling electrons can be encouraged by locating a resonator close to the tunnel junction and applying an appropriate voltage-bias. However, studies of normal metals show that the resonator also affects how the charges flow, facil...

Subradiance-protected excitation transport (2019)
Journal Article

We explore excitation transport within a one-dimensional chain of atoms where the atomic transition dipoles are coupled to the free radiation field. When the atoms are separated by distances smaller or comparable to the wavelength of the transition,... Read More about Subradiance-protected excitation transport.

Strong zero modes in a class of generalized Ising spin ladders with plaquette interactions (2019)
Journal Article

© 2019 American Physical Society. We study a class of spin-1/2 quantum ladder models with generalized plaquette interactions in the presence of a transverse field. We show that in certain parameter regimes, these models have strong zero modes respons... Read More about Strong zero modes in a class of generalized Ising spin ladders with plaquette interactions.

Black holes, gravitational waves and fundamental physics: A roadmap (2019)
Journal Article

© 2019 IOP Publishing Ltd. The grand challenges of contemporary fundamental physics-dark matter, dark energy, vacuum energy, inflation and early universe cosmology, singularities and the hierarchy problem-all involve gravity as a key component. And o... Read More about Black holes, gravitational waves and fundamental physics: A roadmap.

Josephson junction cavity systems as cousins of the quantum optical micromaser (2019)
Journal Article

We explore the similarities and differences between simple theoretical models developed to describe the quantum optical micromaser and Josephson-photonics devices. Whilst the micromaser has long been recognised as an important model for the dynamics... Read More about Josephson junction cavity systems as cousins of the quantum optical micromaser.

Spontaneous scalarization in generalized scalar-tensor theory (2019)
Journal Article

Spontaneous scalarization is a mechanism that endows relativistic stars and black holes with a nontrivial configuration only when their spacetime curvature exceeds some threshold. The standard way to trigger spontaneous scalarization is via a tachyon... Read More about Spontaneous scalarization in generalized scalar-tensor theory.

The relationship between negative BOLD responses and ERS and ERD of alpha/beta oscillations in visual and motor cortex (2019)
Journal Article

Previous work has investigated the electrophysiological origins of the intra-modal (within the stimulated sensory cortex) negative BOLD fMRI response (NBR, decrease from baseline) but little attention has been paid to the origin of cross-modal NBRs,...

Classification of shift-symmetric Horndeski theories and hairy black holes (2019)
Journal Article

No-hair theorems for scalar-tensor theories imply that the trivial scalar field configuration is the unique configuration around stationary black hole spacetimes. The most basic assumption in these theorems is that a constant scalar configuration is... Read More about Classification of shift-symmetric Horndeski theories and hairy black holes.

Journal Article

Virtual reality (VR) provides an immersive environment in which a participant can experience a feeling of presence in a virtual world. Such environments generate strong emotional and physical responses and have been used for wide-ranging applications... Read More about Towards OPM-MEG in a virtual reality environment.
