31. Conflicting Observations Resolved by a Far IR and UV/Vis Study of the NO^d3^ Radical
Topic: Physics
Published: 5/4/2009
Authors: Helmut Beckers, Helge Willner, Marilyn E Jacox
Abstract: By codeposition of NO/Ne and O2/Ne mixtures at 6 K, weakly bound complexes between O2 and NO are formed. They exhibit a strong, structured charge transfer UV band at lambda(max) = 275 nm. The UV band disappears during UV irradiation of the neon mat ...

32. Controlling the Competition between Optically Induced Ultrafast Spin-Flip Scattering and Spin Transport in Magnetic Multilayers
Topic: Physics
Published: 5/7/2013
Authors: Justin M Shaw, Hans Toya Nembach, Thomas J Silva, Margaret M. Murnane, Henry C. Kapteyn, Martin Aeschlimann, Claus M. Schneider, Emrah Turgut, Stefan Mathias, Patrik Grychtol, Chan La-O-Vorakiat, Dennis Rudolf, Roman Adam
Abstract: The study of ultrafast dynamics in magnetic materials provides rich opportunities for greater fundamental understanding of correlated phenomena in solid-state matter, because many of the basic microscopic mechanisms involved are as-yet unclear and ar ...

33. Coupled quantized mechanical oscillators
Topic: Physics
Published: 3/10/2011
Authors: Kenton R. Brown, Christian Ospelkaus, Yves Colombe, Andrew C Wilson, Dietrich G Leibfried, David J Wineland
Abstract: The harmonic oscillator is one of the simplest physical systems but also one of the most fundamental. It is ubiquitous in nature, often serving as an approximation for a more complicated system or as a building block for larger models. Realizations o ...

34. Critically Evaluated Energy Levels and Spectral Lines of Singly Ionized Indium (In II)
Series: Journal of Research (NIST JRES)
Report Number: 118.004
Topic: Physics
Published: 1/14/2013
Author: Alexander Kramida
Abstract: A comprehensive list of the best measured wavelengths in the In II spectrum has been compiled. Uncertainties of the wavelength measurements have been analyzed, and existing inconsistencies have been resolved. An optimized set of fine-structure en ...

35. Cross-validation of microfabricated atomic magnetometers with SQUIDs for biomagnetic applications
Topic: Physics
Published: 9/28/2010
Authors: Svenja A Knappe, Tillman H. Sander, Olaf Kosch, Frank Wiekhorst, John E Kitching, Lutz Trahms
Abstract: A chip-scale atomic magnetometer (CSAM) is compared with a superconducting quantum interference devices (SQUID) sensor in two biomedical applications. CSAMs are magnetic field sensors that operate at room temperature and are based on spectroscopy of ...

36. Cryogenic Design and Performance of an Apparatus for Magnetically Trapping Ultracold Neutrons
Topic: Physics
Published: 10/5/2014
Author: Hans P Mumm
Abstract: The cryogenic design and performance of an apparatus used to magnetically confine ultracold neutrons (UCN) is presented. The apparatus is part of an effort to measure the beta-decay lifetime of the free neutron and is comprised of a high-current su ...

37. Crystalline Order in Laser-cooled, Non-neutral Ion Plasmas
Topic: Physics
Published: 1/1/2000
Authors: John J Bollinger, T M Mitchell, X -P Huang, Wayne M Itano, Joseph N Tan, Branislav M. Jelenkovic, David J Wineland

38. Decoherence due to elastic Rayleigh scattering
Topic: Physics
Published: 11/12/2010
Authors: Hermann Uys, Michael J. Biercuk, Aaron Vandevender, Christian Ospelkaus, Dominic Meiser, R. Ozeri, John J Bollinger
Abstract: We present theoretical and experimental studies of the decoherence of hyperfine ground-state superpositions due to elastic Rayleigh scattering of off-resonant light. We demonstrate that under appropriate conditions, elastic Rayleigh scattering can b ...

39. Dedicated NOAA/JPSS VIIRS Ocean Color Calibration/Validation Cruise
Topic: Physics
Published: 6/12/2015
Authors: Bettye C Johnson, Michael Ondrusek, Eric Stengel, Veronica P. Lance, Menghua Wang, Kenneth Voss, Giuseppe Zibordi, Marko Talone, Zhongping Lee, Jianwei Wei, Junfang Lin, Chuanmin Hu, David English, Charles Kovach, Jennifer Cannizzaro, Alex Gilerson, Sam Ahmed, Ahmed El-Habashi, Robert Foster, Robert Arnone, Ryan Vandermeulen, Sherwin Ladner, Wesley Goode, Joaquim I Goes, Helga de Rosario Gomes, Alex Chekalyuk, Kali McKee, Scott Freeman, Aimee Neeley, Amir Ibrahim
Abstract: The NOAA/STAR Ocean Color team is focused on ,end-to-endŠ production of ocean color satellite products. In situ validation of satellite data is essential to producing the high-quality products required and expected by the international ocean color re ...

40. Demonstrating a High Symmetric Single-Photon Heralding Efficiency in Spontaneous Parametric Downconversion
Topic: Physics
Published: 5/6/2013
Authors: Marcelo Pereira, Francisco E. Becerra Chavez, Boris L. Glebov, Jingyun Fan, Sae Woo Nam, Alan L Migdall
Abstract: We demonstrate a symmetric, single-spatial mode, single-photon heralding efficiency of 84% for a type-II spontaneous parametric downconversion process. This achievement of high efficiency, single-spatial mode collection is key to enabling many quantu ...
