Non-linear Sagnac interferometry for pump-probe dispersion spectroscopy (2003)
Journal Article
Jundt, G., Purves, G., Adams, C., & Hughes, I. (2003). Non-linear Sagnac interferometry for pump-probe dispersion spectroscopy. The European Physical Journal D, 27(3), 273-276. https://doi.org/10.1140/epjd/e2003-00275-5

We explore pump-probe non-linear Sagnac interferometry as a tool to measure the dispersive properties of a medium. We introduce the background theory, and show experimental spectra obtained on the D2 transition with 85Rb and 87Rb. The measured disper...

The influence of grains on the propagation and structure of C-type shock waves in interstellar molecular clouds (2003)
Journal Article
Flower, D., & Pineau des Forêts, G. (2003). The influence of grains on the propagation and structure of C-type shock waves in interstellar molecular clouds. Monthly Notices of the Royal Astronomical Society, 343(2), 390-400. https://doi.org/10.1046/j.1365-8711.2003.06716.x

Gas–grain interactions can have important consequences for the physics and chemistry of shock waves propagating in molecular clouds. The grains can be both a source and a sink of molecules, and their inertia can modify the dynamics of the propagation...

Spin coupling between cold atoms and the thermal fluctuations of a metal surface (2003)
Journal Article
Jones, M., Vale, C., Sahagun, D., Hall, B., & Hinds, E. (2003). Spin coupling between cold atoms and the thermal fluctuations of a metal surface. Physical Review Letters, 91(8), https://doi.org/10.1103/physrevlett.91.080401

We describe an experiment in which Bose-Einstein condensates and cold atom clouds are held by a microscopic magnetic trap near a room-temperature metal wire 500 m in diameter. The lifetime for atoms to remain in the microtrap is measured over a range... Read More about Spin coupling between cold atoms and the thermal fluctuations of a metal surface.

Soliton-sound interactions in quasi-one-dimensional Bose-Einstein condensates (2003)
Journal Article

Longitudinal confinement of dark solitons in quasi-one-dimensional Bose-Einstein condensates leads to sound emission and reabsorption.We perform quantitative studies of the dynamics of a soliton oscillating in a tight dimple trap, embedded in a weake...

Deformation of dark solitons in inhomogeneous Bose–Einstein condensates. (2003)
Journal Article
Parker, N., Proukakis, N., Leadbeater, M., & Adams, C. (2003). Deformation of dark solitons in inhomogeneous Bose–Einstein condensates. Journal of Physics B: Atomic, Molecular and Optical Physics, 36(13), 2891-2910. https://doi.org/10.1088/0953-4075/36/13/318

A dark soliton becomes unstable when it is incident on a background density gradient, and the induced instability results in the emission of sound. Detailed quantitative studies of sound emission are performed for various potentials, such as steps, l... Read More about Deformation of dark solitons in inhomogeneous Bose–Einstein condensates..

Laser cooling of calcium in a 'golden ratio' quasi-electrostatic lattice (2003)
Journal Article
Adams, C., Cox, S., Riis, E., & Arnold, A. (2003). Laser cooling of calcium in a 'golden ratio' quasi-electrostatic lattice. Journal of Physics B: Atomic, Molecular and Optical Physics, 36(10), 1933-1942. https://doi.org/10.1088/0953-4075/36/10/304

A 3D lattice based on a high-power CO2 laser is considered in the context of laser cooling and trapping of atomic calcium. We expect to be able to realize a system with >10 000 lattice sites each with more than 100 atoms, and the facility to laser co...

Experimental observation of high-order quantum accelerator modes (2003)
Journal Article

Using a freely falling cloud of cold cesium atoms periodically kicked by pulses from a vertical standing wave of laser light, we present the first experimental observation of high-order quantum accelerator modes. This confirms the recent prediction b... Read More about Experimental observation of high-order quantum accelerator modes.
