Ultracold Atoms and Precise Time Standards

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

Block copolymer photonic gel for mechanochromic sensing

Author(s)
Edwin Chan, Joseph J. Walish, Edwin L. Thomas, Christopher Stafford
In this work, we describe a strategy based on mechanochromic sensing, the coupling between mechanical and optical properties, of a block copolymer photonic gel

High-Resolution Infrared Spectra of Spiropentane, C5H8

Author(s)
Alfons Weber, J E. Price, K A. Coulterpark, Tony Masiello, Joseph W. Nibler, A Maki, Thomas A. Blake
Infrared spectra of spiropentane (C5H8) have been recorded at a resolution (0.002 cm-1) sufficient to resolve for the first time individual rovibrational lines

5 MHz Phase Detector With Low Residual Flicker

Author(s)
Corey A. Barnes, Archita Hati, Craig W. Nelson, David A. Howe
The measurement of close-to carrier phase modulation (PM) noise of state-of-the-art oscillators is always challenging. Quite often the residual noise of the

Standards and Biometrics

Author(s)
Bradford J. Wing
This paper addresses the importance of standards when implementing or using biometric systems. Standards have been developed to ensure that biometric systems

Magnetization textures in NiPd nanostructures

Jean-Yves Chauleau, Benjamin James McMorran, R. Belkhou, Nicolas Bergeard, Tevfik Mente?, Miguel Angel Nino, Andrea Locatelli, John Unguris, Stanislas Rohart, Jacques Miltat, Andre Thiaville
We have observed peculiar magnetization textures in Ni80Pd20 nanostructures, by three different imaging techniques (MFM, XMCD-PEEM and SEMPA). The appearance of

Single-qubit-gate error below 10-4 in a trapped ion

Author(s)
Kenton R. Brown, Andrew C. Wilson, Yves Colombe, Christian Ospeklaus, Adam M. Meier, Emanuel H. Knill, Dietrich G. Leibfried, David J. Wineland
In theory, quantum computers can solve certain problems much more efficiently than classical computers [1]. This has motivated experimental efforts to construct

Structure of lithium peroxide

Author(s)
Eric L. Shirley, Maria K. Chan, Naba Karan, Mahalingam Balasubramanian, Yang Ren, Jeffrey P. Greeley, Timothy T. Fister
The reliable identification of lithium oxides species, especially lithium peroxide (Li2O2), is of vital importance to the study of Li-air batteries. Previous x

Frequency-stabilization to 6x10-16 via spectral-hole burning

Author(s)
Michael J. Thorpe, Tara M. Fortier, Matthew S. Kirchner, Till P. Rosenband, Lars Rippe
We demonstrate two-stage laser stabilization based on a combination of Fabry-Pérot and spectral-hole burning techniques. The laser is first pre-stabilized by

Pulse Terahertz Reflection/Scattering Measurement

Author(s)
Shu Z. Lo, Edwin J. Heilweil
We report a method to measure reflection and scattering from several samples with different degrees of surface roughness and material properties at terahertz
