On the one hand, Andriot and Roupec (Fortsch Phys, 1800105, 2019) proposed an alternative refined de Sitter conjecture, which gives a natural condition on a combination of the first and second derivatives of the scalar potential (Andriot and Roupec 2...

On the Use of Carbon Cables from Plastic Solvent Combinations of Polystyrene and Toluene in Carbon Nanotube Synthesis (2021)
Journal Article

For every three people on the planet, there are approximately two Tonnes (Te) of plastic waste. We show that carbon recovery from polystyrene (PS) plastic is enhanced by the coaddition of solvents to grow carbon nanotubes (CNTs) by liquid injection c...

Topographic Control of Order in Quasi-2D Granular Phase Transitions (2021)
Journal Article

We experimentally investigate the nature of 2D phase transitions in a quasi-2D granular fluid. Using a surface decorated with periodically spaced dimples we observe interfacial tension between coexisting granular liquid and crystal phases. Measuremen...

SELCIE: a tool for investigating the chameleon field of arbitrary sources (2021)
Journal Article

The chameleon model is a modified gravity theory that introduces an additional scalar field that couples to matter through a conformal coupling. This `chameleon field' possesses a screening mechanism through a nonlinear self-interaction term which al...

Optically Gated Terahertz-Field-Driven Switching of Antiferromagnetic CuMnAs (2021)
Journal Article

We show scalable and complete suppression of the recently reported terahertz-pulse-induced switching between different resistance states of antiferromagnetic CuMnAs thin films by ultrafast gating. The gating functionality is achieved by an optically... Read More about Optically Gated Terahertz-Field-Driven Switching of Antiferromagnetic CuMnAs.

Structure of the human Ccr4-Not nuclease module using X-ray crystallography and electron paramagnetic resonance spectroscopy distance measurements (2021)
Journal Article

Regulated degradation of mature, cytoplasmic mRNA is a key step in eukaryotic gene regulation. This process is typically initiated by the recruitment of deadenylase enzymes by cis-acting elements in the 3' untranslated region resulting in the shorten...

BCS-BEC crossover of ultracold ions driven by density-dependent short-range interactions in a quantum plasma (2021)
Journal Article

We study theoretically a Bardeen-Cooper-Schrieffer (BCS) to Bose-Einstein condensate (BEC) crossover of two-species ions in a three-dimensional quantum plasma at zero temperature. Central to this crossover is an effective short-ranged, attractive int...

Brain structural covariance network differences in adults with alcohol dependence and heavy-drinking adolescents (2021)
Journal Article

BACKGROUND AND AIMS: Graph theoretic analysis of structural covariance networks (SCN) provides an assessment of brain organization that has not yet been applied to alcohol dependence (AD). We estimated whether SCN differences are present in adults wi... Read More about Brain structural covariance network differences in adults with alcohol dependence and heavy-drinking adolescents.

A multi-scale integrated assessment model to support urban sustainability (2021)
Journal Article

Tools purposed towards supporting the transition to more sustainable urban futures typically focus on specific phenomena at the local level. Whilst such approaches remain valuable, there is a need to complement this micro approach with broader integr...

Systematic-Error-Tolerant Multiqubit Holonomic Entangling Gates (2021)
Journal Article

Quantum holonomic gates hold built-in resilience to local noises and provide a promising approach for implementing fault-tolerant quantum computation. We propose to realize high-fidelity holonomic (N + 1)-qubit controlled gates using Rydberg atoms co... Read More about Systematic-Error-Tolerant Multiqubit Holonomic Entangling Gates.

A High-Resolution Investigation of the Multi-Phase ISM in a Galaxy during the First Two Billion Years (2021)
Journal Article

We have carried out the first spatially-resolved investigation of the multi-phase interstellar medium (ISM) at high redshift, using the z = 4.24 strongly-lensed sub-millimetre galaxy H-ATLASJ142413.9+022303 (ID141). We present high-resolution (down t... Read More about A High-Resolution Investigation of the Multi-Phase ISM in a Galaxy during the First Two Billion Years.

Insights into the Structure and Self‐Assembly of Organic‐Semiconductor/Quantum‐Dot Blends (2021)
Journal Article

Controlling the dispersibility of crystalline inorganic quantum dots (QD) within organic-QD nanocomposite films is critical for a wide range of optoelectronic devices. A promising way to control nanoscale structure in these nanocomposites is via the... Read More about Insights into the Structure and Self‐Assembly of Organic‐Semiconductor/Quantum‐Dot Blends.

Satellite quenching was not important for z ∼1 clusters: Most quenching occurred during infall (2021)
Journal Article

We quantify the relative importance of environmental quenching versus pre-processing in z ∼1 clusters by analysing the infalling galaxy population in the outskirts of 15 galaxy clusters at 0.8 < z < 1.4 drawn from the GOGREEN and GCLASS surveys. We f... Read More about Satellite quenching was not important for z ∼1 clusters: Most quenching occurred during infall.

New constraints on light axion-like particles using Chandra transmission grating spectroscopy of the powerful cluster-hosted quasar H1821+643 (2021)
Journal Article

Axion-like particles (ALPs) are predicted by several Beyond the Standard Model theories, in particular, string theory. In the presence of an external magnetic field perpendicular to the direction of propagation, ALPs can couple to photons. Therefore,...

Realizing topologically ordered states on a quantum processor (2021)
Journal Article

The discovery of topological order has revised the understanding of quantum matter and provided the theoretical foundation for many quantum error-correcting codes. Realizing topologically ordered states has proven to be challenging in both condensed... Read More about Realizing topologically ordered states on a quantum processor.

Multipolar Fermi-surface deformation in a Rydberg-dressed Fermi gas with long-range anisotropic interactions (2021)
Journal Article

We study theoretically the deformation of the Fermi surface (FS) of a three-dimensional gas of Rydberg-dressed 6Li atoms.

An inventory of galaxies in cosmic filaments feeding galaxy clusters: galaxy groups, backsplash galaxies, and pristine galaxies (2021)
Journal Article

Galaxy clusters grow by accreting galaxies from the field and along filaments of the cosmic web. As galaxies are accreted they are affected by their local environment before they enter (pre-processing), and traverse the cluster potential. Observation...
