Journal Article
Sabín, C., White, A., Hackermuller, L., & Fuentes, I. (2014). Impurities as a quantum thermometer for a Bose-Einstein condensate. Scientific Reports, 4, 1-6. https://doi.org/10.1038/srep06436

We introduce a primary thermometer which measures the temperature of a Bose-Einstein Condensate in the sub-nK regime. We show, using quantum Fisher information, that the precision of our technique improves the state-of-the-art in thermometry in the s...

Optomechanics, which explores the fundamental coupling between light and mechanical motion, has made important advances in manipulating macroscopic mechanical oscillators down to the quantum level. However, dynamical effects related to the vectorial... Read More about Bidimensional nano-optomechanics and topological backaction in a non-conservative radiation force field.

MegaMorph - multiwavelength measurement of galaxy structure: physically meaningful bulge-disc decomposition of galaxies near and far (2014)
Journal Article
Vika, M., Bamford, S. P., Haussler, B., & Rojas, A. L. (2014). MegaMorph - multiwavelength measurement of galaxy structure: physically meaningful bulge-disc decomposition of galaxies near and far. Monthly Notices of the Royal Astronomical Society, 444(4), https://doi.org/10.1093/mnras/stu1696

Bulge–disc decomposition is a valuable tool for understanding galaxies. However, achieving robust measurements of component properties is difficult, even with high-quality imaging, and it becomes even more so with the imaging typical of large surveys...

Anisotropic magnetoresistance in an antiferromagnetic semiconductor (2014)
Journal Article

Recent studies in devices comprising metal antiferromagnets have demonstrated the feasibility of a novel spintronic concept in which spin-dependent phenomena are governed by an antiferromagnet instead of a ferromagnet. Here we report experimental obs... Read More about Anisotropic magnetoresistance in an antiferromagnetic semiconductor.

Context. The submillimetre-bright galaxy population is believed to comprise, aside from local galaxies and radio-loud sources, intrinsically active star-forming galaxies, the brightest of which are lensed gravitationally. The latter enable studies at... Read More about Herschel-ATLAS and ALMA: HATLAS J142935.3-002836, a lensed major merger at redshift 1.027.

Vernier templating exploits a mismatch between the number of binding sites in a template and a reactant to direct the formation of a product that is large enough to bind several template units. Here, we present a detailed study of the Vernier-templat... Read More about Vernier-Templated Synthesis, Crystal Structure, and Supramolecular Chemistry of a 12-Porphyrin Nanoring.
