Journal Article
Wang, M., Marshall, R., Edmonds, K., Rushforth, A., Campion, R., & Gallagher, B. (2014). Determining Curie temperatures in dilute ferromagnetic semiconductors: high Curie temperature (Ga,Mn)As. Applied Physics Letters, 104, Article 132406. https://doi.org/10.1063/1.4870521

In this paper, we use simultaneous magnetometry and electrical transport measurements to critically examine ways in which the Curie temperature (TC) values have been determined in studies of dilute magnetic semiconductors. We show that, in sufficient... Read More about Determining Curie temperatures in dilute ferromagnetic semiconductors: high Curie temperature (Ga,Mn)As.

Uncertainties in forces extracted from non-contact atomic force microscopy measurements by fitting of long-range background forces (2014)
Journal Article
Sweetman, A., & Stannard, A. (2014). Uncertainties in forces extracted from non-contact atomic force microscopy measurements by fitting of long-range background forces. Beilstein Journal of Nanotechnology, 5, https://doi.org/10.3762/bjnano.5.45

In principle, non-contact atomic force microscopy (NC-AFM) now readily allows for the measurement of forces with sub-nanonewton precision on the atomic scale. In practice, however, the extraction of the often desired ‘short-range’ force from the expe...

A new method for classifying galaxy SEDs from multiwavelength photometry (2014)
Journal Article
Wild, V., Almaini, O., Cirasuolo, M., Dunlop, J., McLure, R., Bowler, R., Ferreira, J., Bradshaw, E., Chuter, R., & Hartley, W. (in press). A new method for classifying galaxy SEDs from multiwavelength photometry. Monthly Notices of the Royal Astronomical Society, 440(2), https://doi.org/10.1093/mnras/stu212

We present a new method to classify the broad-band optical–near-infrared spectral energy distributions (SEDs) of galaxies using three shape parameters (super-colours) based on a principal component analysis of model SEDs. As well as providing a compa... Read More about A new method for classifying galaxy SEDs from multiwavelength photometry.

Self-consistent phase-space distribution function for the anisotropic dark matter halo of the Milky Way (2014)
Journal Article
Fornasa, M., & Green, A. M. (2014). Self-consistent phase-space distribution function for the anisotropic dark matter halo of the Milky Way. Physical Review D - Particles, Fields, Gravitation and Cosmology, 89(6), Article 063531. https://doi.org/10.1103/physrevd.89.063531

Dark Matter (DM) direct detection experiments usually assume the simplest possible ‘Standard Halo Model’ for the Milky Way (MW) halo in which the velocity distribution is Maxwellian. This model assumes that the MW halo is an isotropic, isothermal sph... Read More about Self-consistent phase-space distribution function for the anisotropic dark matter halo of the Milky Way.

Fast transient networks in spontaneous human brain activity (2014)
Journal Article
Baker, A. P., Brookes, M. J., Rezek, I. A., Smith, S. M., Behrens, T., Probert Smith, P. J., & Woolrich, M. W. (2014). Fast transient networks in spontaneous human brain activity. eLife, 3, Article e01867. https://doi.org/10.7554/eLife.01867

To provide an effective substrate for cognitive processes, functional brain networks should be able to reorganize and coordinate on a sub-second temporal scale. We used magnetoencephalography recordings of spontaneous activity to characterize whole-b... Read More about Fast transient networks in spontaneous human brain activity.

iSense: a technology platform for cold atom based quantum technologies (2014)
Presentation / Conference Contribution
Bongs, K., Malcolm, J., Ramelloo, C., Zhu, L., Boyer, V., Valenzuela, T., Maclean, J., Piccardo-Selg, A., Mellor, C., Fernholz, T., Fromhold, M., Krüger, P., Hellmig, O., Grote, A., Dörscher, S., Duncker, H., Windpassinger, P., Sengstock, K., Becker, C., Pelle, B., …Wicht, A. iSense: a technology platform for cold atom based quantum technologies. Presented at Quantum Information and Measurement 2014

A breakthrough in cold atom quantum technology is hindered by a bottleneck in the supporting technologies. We discuss a cold atom technology platform developed within the European iSense project, aiming at a gravimeter as demonstrator.

Subterahertz chaos generation by coupling a superlattice to a linear resonator (2014)

Physical Review Letters, 112(116603), https://doi.org/10.1103/PhysRevLett.112.116603

We investigate the effects of a linear resonator on the high-frequency dynamics of electrons in devices exhibiting negative differential conductance. We show that the resonator strongly affects both the dc and ac transport characteristics of the devi...

The origin of so-called “subatomic” resolution in dynamic force microscopy has remained controversial since its first observation in 2000. A number of detailed experimental and theoretical studies have identified different possible physicochemical me...

Evidence that the negative BOLD response is neuronal in origin: a simultaneous EEG–BOLD–CBF study in humans (2014)
Journal Article
Mullinger, K. J., Mayhew, S. D., Bagshaw, A. P., Bowtell, R. W., & Francis, S. T. (2014). Evidence that the negative BOLD response is neuronal in origin: a simultaneous EEG–BOLD–CBF study in humans. NeuroImage, 94, https://doi.org/10.1016/j.neuroimage.2014.02.029

Unambiguous interpretation of changes in the BOLD signal is challenging because of the complex neurovascular coupling that translates changes in neuronal activity into the subsequent haemodynamic response. In particular, the neurophysiological origin... Read More about Evidence that the negative BOLD response is neuronal in origin: a simultaneous EEG–BOLD–CBF study in humans.
