Journal ArticleDOI
Superflow in a Toroidal Bose-Einstein Condensate: An Atom Circuit with a Tunable Weak Link
Anand Ramanathan,Kevin Wright,Sérgio Ricardo Muniz,Martin Zelan,Wendell T. Hill,Christopher Lobb,Kristian Helmerson,William D. Phillips,Gretchen K. Campbell +8 more
TL;DR: A long-lived persistent current is created in a toroidal Bose-Einstein condensate held in an all-optical trap and is consistent with dissipation due to the creation of vortex-antivortex pairs.
Journal ArticleDOI
Generation of nondiffracting Bessel beams by use of a spatial light modulator
TL;DR: The characteristics of a singularity in a nondiffracting Bessel beam is explored experimentally by use of a programmable spatial light modulator with 64-level phase holograms and the diffraction efficiency is greatly improved.
Journal ArticleDOI
Long, narrow all-light atom guide.
Y. Song,D. Milam,Wendell T. Hill +2 more
TL;DR: A 1-mm-diameter all-light atom guide capable of transporting ultracold atoms tens of centimeters with high efficiency is described and it is shown that it is possible for one to control the direction and speed of the atoms in the tunnel by varying the detuning of the tunnel beam.
Journal ArticleDOI
Precision lifetime measurements of Cs 6p 2P1/2 and 6p 2P3/2 levels by single-photon counting.
L. Young,Wendell T. Hill,S. J. Sibener,Stephen D. Price,Carol E. Tanner,Carl E. Wieman,Stephen R. Leone +6 more
TL;DR: In this article, a femtosecond self-mode-locked Ti:sapphire laser is used to excite Cs produced in a well-collimated atomic beam.
Journal ArticleDOI
Contact resistance and phase slips in mesoscopic superfluid-atom transport
Stephen Eckel,Jeffrey G. Lee,Fred Jendrzejewski,Christopher Lobb,Gretchen K. Campbell,Wendell T. Hill +5 more
TL;DR: In this article, the authors experimentally measure transport of superfluid, bosonic atoms in a mesoscopic system: a small channel connecting two large reservoirs, and observe first resistive flow transitioning at a critical current into superflow, characterized by oscillations.
