Journal Article
De Geyter, G., Baes, M., De Looze, I., Bendo, G., Bourne, N., Camps, P., …Viaene, S. (2015). Dust energy balance study of two edge-on spiral galaxies in the Herschel-ATLAS survey. Monthly Notices of the Royal Astronomical Society, 451(2), https://doi.org/10.1093/mnras/stv1104

Interstellar dust in galaxies can be traced either through its extinction effects on the star light or through its thermal emission at infrared wavelengths. Recent radiative transfer studies of several nearby edge-on galaxies have found an apparent i...

Spin correlations as a probe of quantum synchronization in trapped ion phonon-lasers (2015)
Journal Article

We investigate quantum synchronization theoretically in a system consisting of two cold ions in microtraps. The ions' motion is damped by a standing-wave laser whilst also being driven by a blue-detuned laser which results in self-oscillation. Workin...
