Journal ArticleDOI
Dynamics of collapsing and exploding Bose–Einstein condensates
Elizabeth A. Donley,Elizabeth A. Donley,Neil R. Claussen,Neil R. Claussen,Simon L. Cornish,Simon L. Cornish,J. L. Roberts,J. L. Roberts,Eric A. Cornell,Eric A. Cornell,Carl E. Wieman,Carl E. Wieman +11 more
TL;DR: In this article, the authors explore the dynamics of how a Bose-Einstein condensate collapses and subsequently explodes when the balance of forces governing its size and shape is suddenly altered.
Journal ArticleDOI
Atom-molecule coherence in a Bose-Einstein condensate.
TL;DR: The oscillation frequency is in excellent agreement with the theoretical molecular binding energy, indicating that the author has created a quantum superposition of atoms and diatomic molecules—two chemically different species.
Journal ArticleDOI
Controlled Collapse of a Bose-Einstein Condensate
J. L. Roberts,J. L. Roberts,Neil R. Claussen,Neil R. Claussen,Simon L. Cornish,Simon L. Cornish,Elizabeth A. Donley,Elizabeth A. Donley,Eric A. Cornell,Eric A. Cornell,Carl E. Wieman,Carl E. Wieman +11 more
TL;DR: The point of instability of a Bose-Einstein condensate (BEC) due to attractive interactions was studied and was determined to be N(absolute value of a) / a(ho) = 0.012+/-0.054, slightly lower than the predicted value of 0.574.
Journal ArticleDOI

TL;DR: A comparison between the cesium fountain standard NIST-F1, which has been evaluated with an inaccuracy of about 4 x 10 (-16), and an optical frequency standard based on an ultraviolet transition in a single, laser-cooled mercury ion for which the fractional systematic frequency uncertainty was below 7.2 x 10(-17).
Journal ArticleDOI
Atomic Sensors – A Review
TL;DR: In this article, the basic physics and instrumentation issues related to high-performance physical and inertial sensors based on atomic spectroscopy are discussed, with a focus on precision sensing of electromagnetic and gravitational fields.
