Tunnelling induced collapse of an atomic Bose–Einstein condensate in a double-well potential. (2004)
Journal Article
Sakellari, E., Proukakis, N., & Adams, C. (2004). Tunnelling induced collapse of an atomic Bose–Einstein condensate in a double-well potential. Journal of Physics B: Atomic, Molecular and Optical Physics, 37(18), 3681-3690. https://doi.org/10.1088/0953-4075/37/18/009

The stability of a low-temperature Bose–Einstein condensate with attractive interactions in one- and three-dimensional double-well potentials is discussed. In particular, the tunnelling dynamics of a condensate under the influence of a time-dependent...

Controlled vortex-sound interactions in atomic Bose-Einstein condensate (2004)
Journal Article
Parker, N., Proukakis, N., Barenghi, C., & Adams, C. (2004). Controlled vortex-sound interactions in atomic Bose-Einstein condensate. Physical Review Letters, 92(16), https://doi.org/10.1103/physrevlett.92.160403

The low temperature dynamics of a vortex in a trapped quasi-two-dimensional Bose-Einstein condensate are studied quantitatively. Precession of an off-centered vortex in a dimple trap, embedded in a weaker harmonic trap, leads to the emission of sound...

Josephson tunnelling of a phase-imprinted Bose-Einstein condensate in a time-dependent double-well potential (2004)
Journal Article
Sakellari, E., Proukakis, N., Leadbeater, M., & Adams, C. (2004). Josephson tunnelling of a phase-imprinted Bose-Einstein condensate in a time-dependent double-well potential. New Journal of Physics, 6, Article 42. https://doi.org/10.1088/1367-2630/6/1/042

This paper discusses the feasibility of experimental control of the flow direction of atomic Bose–Einstein condensates in a double-well potential using phase imprinting. The flow is induced by the application of a time-dependent potential gradient, p...

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...

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...
