1. CODATA Recommended Values of the Fundamental Physical Constants: 2010
Series: Special Publication (NIST SP)
Report Number: 961
Topic: Atomic Physics
Published: 3/1/2012
Authors: Peter J Mohr, Barry Norman Taylor, David B Newell
Abstract: NIST SP 961 (Dec/2012)

2. Demonstration of Superluminal Images
Topic: Atomic Physics
Published: 6/19/2012
Authors: Ryan Thomas Glasser, Ulrich Vogl, Paul D Lett
Abstract: Optical pulse propagation with group velocities larger than the speed of light in vacuum, c, or negative, have been demonstrated theoretically and experimentally in a variety of systems [1‹5]. The anomalous dispersion required for generating ,fastŠ l ...

3. Energy Levels and Observed Spectral Lines of Neutral and Singly Ionized Titanium, Ti I and Ti II
Series: J. Phys. & Chem. Ref. Data (JPCRD)
Topic: Atomic Physics
Published: 1/12/2012
Author: Edward Barry Saloman
Abstract: The energy levels and observed spectral lines of neutral and singly ionized titanium atoms have been compiled. Tables of energy levels and spectral lines are generated for each stage. Experimental g-factors and leading percentages are included when ...

4. Low-Frequency Characterization of MEMS-Based Portable Atomic Magnetometer
Topic: Atomic Physics
Published: 6/2/2010
Authors: Rahul R. (Rahul) Mhaskar, Svenja A Knappe, John E Kitching
Abstract: Atomic magnetometers based on absorption or polarization rotation of light in an alkali vapor have recently demonstrated sensitivities rivaling those of superconducting quantum interference devices (SQUIDs). Miniaturization of such devices containing ...

5. Number Enhancement for Compact Laser-Cooled Atomic Samples by use of Stimulated Radiation Forces
Topic: Atomic Physics
Published: 6/2/2010
Authors: Elizabeth A Donley, Tara C. Liebisch, Eric Michael Blanshan, John E Kitching
Abstract: For cold samples of laser-cooled atoms to be most useful in emerging technologies such as compact atomic clocks and sensors, it is necessary to achieve small sample sizes while retaining a large number of cold atoms. We consider achieving large atom ...

6. Observation of a superfluid Hall effect
Topic: Atomic Physics
Published: 7/3/2012
Authors: Lindsay J. LeBlanc, Karina K. Jimenez Garcia, Ross A. Williams, Matthew C. 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 ...

7. Progress at NIST in measuring the D-lines of Li isotopes using an optical frequency comb
Topic: Atomic Physics
Published: 12/20/2010
Authors: Clayton Simien, Samuel Middleton Brewer, Joseph N Tan, John D Gillaspy, Craig J Sansonetti
Abstract: Precise spectroscopic experiments with light atoms can provide information about nuclear properties that are very difficult to obtain in electron scattering experiments. For example, relative nuclear radii of low-Z isotopes can be determined accurat ...

8. Quasi-phasematched Second Harmonic Generation in GaAs Microdisks
Topic: Atomic Physics
Published: 11/15/2009
Authors: Paulina S Kuo, W Fang, Glenn Scott Solomon
Abstract: We discuss design and tuning of second-harmonic generation in GaAs microdisks. Quasi-phasematching can be achieved in the microdisk geometry without external domain inversions, but efficient nonlinear optical mixing requires that all waves be resonan ...

9. Ratio of the Al^u+^ and Hg^u+^ Optical Clock Frequencies to 17 Decimal Places
Topic: Atomic Physics
Published: 8/25/2008
Authors: Wayne M Itano, Till P Rosenband, David Hume, P.O. Schmidt, Chin W. Chou, A. Brusch, Luca Lorini, Windell Oskay, Robert E. Drullinger, Sarah Bickman, Tara Michele Fortier, Jason Stalnaker, Scott A Diddams, William C Swann, Nathan Reynolds Newbury, David J Wineland, James C Bergquist
Abstract: Frequency standards (atomic clocks) based on narrow optical transitions in ^u27^Al^u+^ and ^u199^Hg^u+^ have been developed over the past several years at NIST. These two types of standards are both based on single ions confined in Paul traps, but di ...

10. Stimulated Generation of Superluminal Light Pulses via Four-wave Mixing
Topic: Atomic Physics
Published: 4/26/2012
Authors: Ryan Thomas Glasser, Ulrich Vogl, Paul D Lett
Abstract: We report on the four-wave mixing of superluminal pulses, in which both the injected and generated pulses involved in the process propagate with negative group velocities. Generated pulses with negative group velocities of up to vg = −c/880 ar ...
