Ultracold Atoms and Precise Time Standards

September 19, 2011
Author(s)
Gretchen K. Campbell, William D. Phillips
Experimental techniques of laser cooling and trapping, along with other cooling techniques have produced gaseous samples of atoms so cold that they are, for many practical purposes, in the quantum ground state of their center-of-mass motion. Such low

Continuous Light Shift Correction in Modulated CPT clocks

October 13, 2006
Author(s)
V Shah, Vladislav Gerginov, P Schwindt, Svenja A. Knappe, Leo W. Hollberg, John E. Kitching
We demonstrate a simple technique to significantly improve the long-term frequency stability of atomic clocks based on coherent population trapping (CPT). In this technique, the CPT feilds are created by a modulated diode laser and a slow servo is used to

Characterization of Magnetic Properties at Edges by Edge Mode Dynamics

April 21, 2006
Author(s)
Brian B. Maranville, Robert McMichael, Sudook A. Kim, Ward L. Johnson, C A. Ross, J Cheng
We have used trapped spinwave or edge modes of magnetic precession to probe the magnetic environment near magnetic film edges magnetized perpendicular to the edge. Micromagnetic models of dynamics in stripes reveal that the edge mode frequency-field

Molecular Mass Determination of Saturated Hydrocarbons: Reactivity of eta- 5 -Cyclopentadienylcobalt Ion (CpCo. +) and Linear Alkanes up to C-30

January 1, 2003
Author(s)
H M. Byrd, Kathleen M. Flynn, D P. Ridge
… the feasibility of the h 5 -cyclopentadienylcobalt ion (CpCo +) as a suitable cationization reagent for saturated hydrocarbons analysis by mass spectrometry. Ion/molecule reactions of CpCo + and three medium … n-alkanes were examined using Fourier-transform ion cyclotron resonance mass spectrometry. Second-order rate …

Laser noise cancellation in single-cell CPT clocks

July 1, 2008
Author(s)
Vladislav Gerginov, Svenja A. Knappe, V Shah, Leo W. Hollberg, John E. Kitching
We demonstrate a new technique for the suppression of noise associated with the laser source in atomic clocks based on coherent population trapping. The technique uses differential detection of the transmission of linearly- and circularly-polarized beams
