Measurement of Parity Nonconservation and an Anapole Moment in Cesium
C. S. Wood,S. C. Bennett,Donghyun Cho,B. P. Masterson,J. L. Roberts,Carol E. Tanner,Carl E. Wieman +6 more
TL;DR: The amplitude of the parity-nonconserving transition between the 6S and 7S states of cesium was precisely measured with the use of a spin-polarized atomic beam, providing an improved test of the standard model at low energy, including a value for the S parameter of −1.3(3)exp (11)theory.
Journal ArticleDOI
A Bose-Einstein condensate in an optical lattice
J. Hecker Denschlag,Jesse E. Simsarian,Hartmut Häffner,C. McKenzie,Antoine Browaeys,Donghyun Cho,Kristian Helmerson,Steven L. Rolston,William D. Phillips +8 more
TL;DR: In this article, a Bose-Einstein condensate (BEC) in a one-dimensional optical lattice was used to perform band spectroscopy, where the BEC was loaded into the ground state with a very high efficiency by adiabatically turning on the lattice.
Journal ArticleDOI
Measurement of the Casimir-Polder force.
TL;DR: This experiment provides clear evidence for the existence of the Casimir-Polder force, which is due to modification of the ground-state Lamb shift in the confined space of a cavity, and confirms the magnitude of the force and the distance dependence predicted by quantum electrodynamics.
Journal ArticleDOI
A Bose-Einstein condensate in an optical lattice
J. Hecker Denschlag,Jesse E. Simsarian,H Haeffner,C. McKenzie,Antoine Browaeys,Donghyun Cho,Kristian Helmerson,Steven L. Rolston,William D. Phillips +8 more
TL;DR: In this paper, a Bose-Einstein condensate (BEC) in a one-dimensional optical lattice is used to perform band spectroscopy and coherently transfer population between lattice states and observe their evolution.
Journal ArticleDOI
Photoassociation of sodium in a Bose-Einstein condensate.
C. McKenzie,J. Hecker Denschlag,Hartmut Häffner,Antoine Browaeys,Luís E. E. de Araujo,Fredrik K. Fatemi,Kevin M. Jones,Jesse E. Simsarian,Donghyun Cho,Andrea Simoni,Eite Tiesinga,Paul Julienne,Kristian Helmerson,Paul D. Lett,Steven L. Rolston,William D. Phillips +15 more
TL;DR: The photoassociation rate constant increases linearly with intensity, even where it is predicted that many-body effects might limit the rate.
