1. Observation of a superfluid Hall effect
Topic: Cold Atoms
Published: 7/3/2012
Authors: Lindsay Jane LeBlanc, Karina K. Jimenez Garcia, Ross Alexander Williams, Matthew Charles Beeler, Abigail Reiko Perry, William D Phillips, Ian B Spielman
Abstract: Measurement techniques based upon the Hall effect are essential tools in condensed matter physics. Here, we report the first observation of a Hall effect in an ultracold gas of neutral atoms, revealed by measuring Bose-Einstein condensate's transpo ...

2. Differential Light Shift Cancellation in a B-Field Insensitive Transition of 87Rb
Topic: Cold Atoms
Published: 2/11/2011
Authors: Radu S. Chicireanu, Karl D. Nelson, Steven M Olmschenk, Nathan Lundblad, Andrei Derevianko, James V Porto
Abstract: We demonstrate substantial cancellation of the differential light shift of a magnetic-field-insensitive microwave hyperfine (clock) transition in 87Rb atoms trapped in an optical lattice. Up to 95.5% of the differential light shift is cancelled while ...

3. A Focused Chromium Ion Beam
Topic: Cold Atoms
Published: 10/21/2010
Authors: Adam V Steele, Brenton John Knuffman, Jabez J McClelland, Jon Orloff
Abstract: With the goal of expanding the capabilities of focused ion beam microscopy and milling systems, we have demonstrated nanoscale focusing of chromium ions produced in a magneto-optical trap ion source (MOTIS). Neutral chromium atoms are captured into ...

4. Performance of a feedback-controlled, deterministic source of single Cr atoms
Topic: Cold Atoms
Published: 3/1/2004
Authors: S Hill, Jabez J McClelland
Abstract: A magneto-optic trap with feedback-controlled loading and loss rates is used to realize a deterministic source of single Cr atoms with single-atom occupation probability as high as 0.987 {plus or minus} 0.001. We present a series of measurements of ...

5. A Fast, Deterministic Source of Single Cr Atoms
Topic: Cold Atoms
Published: 6/1/2003
Authors: Jabez J McClelland, Shannon Bradley Hill
Abstract: We produce single Cr atoms on demand by feedback control of loading and loss from a magneto-optical trap. We observe single-atom occupation probabilities of over 98% and efficient ejection at rates up to 10 Hz.

6. Atoms on Demand: Fast, Deterministic Production of Single Cr Atoms
Topic: Cold Atoms
Published: 5/5/2003
Authors: S Hill, Jabez J McClelland
Abstract: We have realized a method for producing single Cr atoms on demand by suppressing the stochastic nature of the loading and loss processes of a magneto-optic trap. We observe single-atom trap occupation probabilities as high as (98.7 {plus or minus} 0. ...
