61. Absolute absorption and dispersion of a rubidium vapour in the hyperfine Paschen-Back regime
Topic: Physics
Published: 10/4/2012
Authors: Svenja A Knappe, L. Weller, K.S. Kleinbach, M.A. Zentile, C.S. Adams, I.G. Hughes
Abstract: Here we report on measurements of the absolute absorption and dispersion properties of an isotopically pure 87Rb vapour for magnetic fields up to and including 0.6 T. We discuss the various regimes which arise when the hyperfine and Zeeman interactio ...

62. Absolute and relative gravity measurements at Hannover and Potsdam in the period 1988-1990
Topic: Physics
Published: 1/1/1991
Authors: W Torge, R H Roder, I Timmen, H Kautzleben, Cl Elstner, J E. Faller

63. Absolute and relative stability of an optical frequency reference based on spectral hole burning in Eu^u3+^:Y^d2^SiO^d5^
Topic: Physics
Published: 12/6/2013
Authors: David R Leibrandt, M Thorpe, Chin W. Chou, Tara Michele Fortier, Scott A Diddams, Till P Rosenband
Abstract: We present four frequency comparison measurements designed to investigate the performance of an optical frequency reference based on spectral hole burning in Eu$^u3+^:Y^d2^SiO^d5^. The first frequency comparison, between a single unperturbed spectral ...

64. Absolute transition frequencies and quantum interference in a frequency comb based measurement of the 6,7Li D lines
Topic: Physics
Published: 7/6/2011
Authors: Craig J Sansonetti, Clayton Simien, John D Gillaspy, Joseph N Tan, Samuel Middleton Brewer, Roger Charles Brown, Saijun Wu, James V Porto
Abstract: Optical frequencies of the D lines of 6,7Li were measured with a relative accuracy of 5x10-11 using an optical comb synthesizer. Quantum interference in the laser induced fluorescence for the partially-resolved D2 lines was found to produce polariz ...

65. Absolute-frequency measurements with a stabilized near-infrared optical frequency comb from a Cr:forsterite laser
Topic: Physics
Published: 2/15/2004
Authors: K L Corwin, I Thomann, A Bartels, T Dennis, Richard W Fox, W C Swann, E A Curtis, Christopher W Oates, G Wilpers, S L Gilbert, Leo W. Hollberg, Nathan Reynolds Newbury, Scott A Diddams, J Nicholson, M. F. Yan

66. Accurate CO^d2^ Laser Frequencies and Molecular Constants for Regular and New Hot Band Lines
Topic: Physics
Published: 6/27/1994
Authors: Che-Chung Chou, Jow-Tsong Shy, A. G. Maki, L R Zink, K M. Evenson

67. Accurate control of Josephson phase qubits
Topic: Physics
Published: 12/30/2003
Authors: Matthias Steffen, John M. Martinis, Isaac C. Chuang
Abstract: A quantum bit is a closed two-dimensional Hilbert space, but often experimental systems have three or more energy levels. In a Josephson phase qubit the energy differences between successive levels differ by only a few percent, and hence care must be ...

68. Accurate light-time correction due to a gravitating mass
Topic: Physics
Published: 6/7/2010
Authors: Neil Ashby, Bruno Bertotti
Abstract: This technical paper of mathematical physics arose as an aftermath of the 2002 Cassini experiment, in which the PPN parameter {gamma} was measured with an accuracy {sigma}^d{gamma}^ {math equal} 2.3 {multiply} 10^u-5^ and found consistent with the re ...

69. Adaptive and robust statistical methods for processing near-field scanning microwave microscopy images
Topic: Physics
Published: 11/23/2014
Authors: Kevin J Coakley, Samuel Berweger, Atif (Atif) Imtiaz, Thomas M Wallis, Joel C. Weber, Pavel Kabos
Abstract: Near-field scanning microwave microscopy offers great potential to facilitate characterization, development and modeling of materials. By acquiring microwave images at multiple frequencies and amplitudes (along with the other modalities) one can stud ...

70. Advances in Atomic Structure Calculations
Topic: Physics
Published: Date unknown
Author: Charlotte Fischer
Abstract: Correlation and relativistic effects are both needed for accurate atomic structure calculations of energy levels and their atomic properties. For transition probabilities between low-lying levels of a spectrum, accurate wave functions for the outer r ...
