Observation of interference effects via four photon excitation of highly excited Rydberg states in thermal cesium vapor (Data files)Jorge M. Kondo, Nikola Šibalić, Alex Guttridge, Christopher G. Wade, Natalia R. De Melo, Charles S. Adams & Kevin J. Weatherill
We report on the observation of Electromagnetically Induced Transparency (EIT) and Absorption (EIA) of highly-excited Rydberg states in thermal Cs vapor using a 4-step excitation scheme. The advantage of this 4-step scheme is that the final transition to the Rydberg state has a large dipole moment and one can achieve similar Rabi frequencies to 2 or 3 step excitation schemes using two orders of magnitude less laser power. Consequently each step is driven by a...

Data from "Spectroscopic detection of atom-surface interactions in an atomic vapour layer with nanoscale thickness"K.A. Whittaker, J. Keaveney, A. Sargsyan, D. Sarkisyan, I.G. Hughes & C.S. Adams
Abstract from article: We measure the resonance line shape of atomic vapor layers with nanoscale thickness confined between two sapphire windows. The measurement is performed by scanning a probe laser through resonance and collecting the scattered light. The line shape is dominated by the effects of Dicke narrowing, self-broadening, and atom-surface interactions. By fitting the measured line shape to a simple model we discuss the possibility to extract information about the atom-surface interaction.

Data from: "From short-time diffusive to long-time ballistic dynamics: the unusual center-of-mass motion of quantum bright solitons"Christoph Weiss, Simon A. Gardiner & Heinz-Peter Breuer
Brownian motion is ballistic on short time scales and diffusive on long time scales. Our theoretical investigations indicate that one can observe the exact opposite - an anomalous diffusion process where initially diffusive motion becomes ballistic on longer time scales - in an ultracold atom system with a size comparable to macromolecules. This system is the center-of-mass motion of a quantum matter-wave bright soliton for which the dominant source of decoherence are three-particle losses. Our...

Enhancing the optical cross section is an enticing goal in light-matter interactions, due to its fundamental role in quantum and non-linear optics. Here, we show how dipolar interactions can suppress off-axis scattering in a two-dimensional atomic array, leading to a subradiant collective mode where the optical cross section is enhanced by almost an order of magnitude. As a consequence, it is possible to attain an optical depth which implies high fidelity extinction, from a monolayer....
Examining charge transport networks in organic bulk heterojunction photovoltaic diodes using 1/f noise spectroscopy (data files)K. Kaku, A.T. Williams, B. Mendis & C. Groves
This study investigates the application of 1/f noise spectroscopy to determine the morphology of organic photovoltaic diodes. Our experiments indicate that 1/f noise spectroscopy can provide detailed information about charge transport networks in such complex, bulk heterojunction devices, even when bipolar charge transport is present. This indicates that 1/f noise spectroscopy could be used to investigate morphology in a wide range blended organic electronic devices. Methodologies and descriptions of the data are described in full...
Data Supporting "Interfacial contribution to thickness dependent in-plane anisotropic magnetoresistance", AIP Advances 5, 127108 (2015)Mustafa Tokac, Mu Wang, Samridh Jaiswal, Andrew Rushforth, Bryan Gallagher, Del Atkinson & Aidan Hindmarch
(Abstract from article) We have studied in-plane anisotropic magnetoresistance(AMR) in cobaltfilms with overlayers having designed electrically interface transparency. With an electrically opaque cobalt/overlayer interface, the AMR ratio is shown to vary in inverse proportion to the cobaltfilm thickness; an indication that in-plane AMR is a consequence of anisotropic scattering with both volume and interfacial contributions. The interface scattering anisotropy opposes the volume scattering contribution, causing the AMR ratio to diminish as the cobaltfilm thickness is...

Minerals are known to stabilise organic carbon in sediments, affecting biogeochemical cycles and global climate, but the mechanism is not understood. Here, the authors suggest that manganese oxides can trap organic carbon and may act as a 'mineral pump', transforming carbon between labile and refractory forms.

There is a striking correlation between terrestrial species' pupil shape and ecological niche (i.e., foraging mode and time of day they are active). Species with vertically elongated pupils are very likely to be ambush predators and active day and night. Species with horizontally elongated pupils are very likely to be prey and to have laterally placed eyes. Vertically elongated pupils create astigmatic depth of field such that images of vertical contours nearer or farther than...

Abstract from article: We describe an apparatus designed to trap and cool a Yb and Cs mixture. The apparatus consists of a dual species effusive oven source, dual species Zeeman slower, magneto-optical traps in a single ultra-high vacuum science chamber, and the associated laser systems. The dual species Zeeman slower is used to load sequentially the two species into their respective traps. Its design is flexible and may be adapted for other experiments with different...

The incorporation of functionalised carbon nanodots within a novel low molecular weight salt hydrogel derived from 5-aminosalycilic acid is reported. The carbon dots result in markedly enhanced gelation properties, while inclusion within the hydrophobic gel results in a dramatic fluorescence enhancement for the carbon nanomaterials. The resulting hybrid CD Gels exhibit a useful sensor response for heavy metal ions, particularly Pb2+.
The data was obtained by using an exact recurrence relation.

Abstract from article: Although considerable progress has been made in simulating the dynamics of multiple coupled nuclear spins, predicting the evolution of nuclear magnetisation in the presence of radio-frequency decoupling remains challenging. We use exact numerical simulations of the spin dynamics under simultaneous magic-angle spinning and RF decoupling to determine the extent to which numerical simulations can be used to predict the experimental performance of heteronuclear decoupling for the CW, TPPM and XiX sequences, using...
