Observation of a Modulational Instability in Bose-Einstein condensates
P. J. Everitt, M. A. Sooriyabandara, M. Guasoni +10
We observe the breakup dynamics of an elongated cloud of condensed Rb atoms placed in an optical waveguide. The number of localized spatial components observed in the breaku…
Observation of Breathers in an Attractive Bose Gas
Patrick J. Everitt, Mahasen A. Sooriyabandara, Gordon D. McDonald +8
In weakly nonlinear dispersive systems, solitons are spatially localized solutions which propagate without changing shape through a delicate balance between dispersion and self-foc…
A Bose-condensed, simultaneous dual species Mach-Zehnder atom interferometer
C. C. N. Kuhn, G. D. McDonald, K. S. Hardman +6
This paper presents the first realisation of a simultaneous Rb -Rb Mach-Zehnder atom interferometer with Bose-condensed atoms. A number of ambitious proposals for pre…
A faster scaling in acceleration-sensitive atom interferometers
Gordon D. McDonald, Carlos C. N. Kuhn, Shayne Bennetts +4
Atom interferometers have been used to measure acceleration with at best a scaling in sensitivity as the interferometer time is increased. This limits the sensitivity to…
80hk Momentum Separation with Bloch Oscillations in an Optically Guided Atom Interferometer
Gordon D. McDonald, Carlos C. N. Kuhn, Shayne Bennetts +5
We demonstrate phase sensitivity in a horizontally guided, acceleration-sensitive atom interferometer with a momentum separation of 80hk between its arms. A fringe visibility of 7%…
Optically guided linear Mach Zehnder atom interferometer
G. D. McDonald, H. Keal, P. A. Altin +7
We demonstrate a horizontal, linearly guided Mach Zehnder atom interferometer in an optical waveguide. Intended as a proof-of-principle experiment, the interferometer utilises a Bo…
Bosenova and three-body loss in a Rb-85 Bose-Einstein condensate
P. A. Altin, G. R. Dennis, G. D. McDonald +5
Collapsing Bose-Einstein condensates are rich and complex quantum systems for which quantitative explanation by simple models has proved elusive. We present new experimental data o…
