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...
