71. 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 ...

73. Superelastic Scattering of Spin-polarized Electrons from Sodium
Topic: Atomic Physics
Published: 9/1/1989
Authors: Jabez J McClelland, Michael H Kelley, Robert Celotta
Abstract: Superelastic scattering of spin-polarized electrons from laser-excited sodium atoms has been measured at incident energies of 2.0, 17.9, and 52.3 eV over the angular range 10{degree}-120{degree}. Circularly polarized excitation of the sodium atoms wa ...

74. Synopsis of the Fifth International Symposium on Polarization and Correlation in Electronic and Atomic Collisions
Topic: Atomic Physics
Published: 1/1/1990
Authors: Michael H Kelley, K Becker, P Neill
Abstract: Electron spin polarization effects and electron-photon angular and polarization correlation studies in electronic and atomic collision processes were the major subjects discussed at the Fifth International Symposium on Polarization and Correlation in ...

75. Towards a compact cold atom frequency standard based on coherent populatoin trapping
Topic: Atomic Physics
Published: 6/2/2010
Authors: Francois-Xavier R. Esnault, Elizabeth A Donley, John E Kitching
Abstract: We describe in this paper the main features of a cold atom CPT based frequency standard. We explain our particular CPT configuration and our experimental setup. as well as present simulations of the expected performance (stability and major systemati ...

76. Uncertainty Intervals for Polarized Beam Scattering Asymmetry Statistics
Topic: Atomic Physics
Published: 7/1/1993
Authors: Kevin J Coakley, Jabez J McClelland, Michael H Kelley, Robert Celotta
Abstract: In many scattering experiments, the quantity of most direct physical interest is a measure of the difference between two closely related scattering signals, each generated by a Poisson scattering process. This difference is often expressed in terms o ...

77. Uncooled, Millimeter-Scale Atomic Magnetometers with Femtotesla Sensitivity
Topic: Atomic Physics
Published: 10/26/2009
Authors: John E Kitching, Svenja A Knappe, William C. Griffith, Jan Preusser, V Gerginov, Peter D. Schwindt, Vishal Shah, Ricardo Jimenez Martinez
Abstract: We summarize recent results at NIST to develop high-performance yet highly miniaturized magnetic sensors based on atomic vapors confined in microfabricated alkali vapor cells. These sensors currently achieve sensitivities in the range of a few tens o ...

78. Uses of Spin-Polarized Electrons in Fundamental Electron-Atom Collision Processes and the Analysis of Magnetic Microstructures
Topic: Atomic Physics
Published: 1/1/1990
Author: Michael H Kelley
Abstract: Two experimental programs are discussed which exploit the use of polarised electrons for studies of fundamental processes and physical properties. In one program, collisions between spin-polarised electrons and optically pubped sodium atoms provide ...

79. Weight Functions for Biases in Atomic Frequency Standards
Topic: Atomic Physics
Published: 10/5/2008
Author: Jon Hardy Shirley
Abstract: We present a unified treatment of frequency-standard biases that vary significantly during the time of measurement. We introduce three time-dependent weight functions built from the solution of the unperturbed equations of motion for a two-level sys ...

80. Weight Functions for Biases in Atomic Frequency Standards
Topic: Atomic Physics
Published: 3/1/2010
Author: Jon Hardy Shirley
Abstract: Many perturbations that affect atomic frequency standards vary during the period of measurement. To include this time variation, we introduce three time-dependent weight functions built from the solution of the unperturbed equations of motion of a t ...
