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...

Rectangular Scale-Similar Etch Pits in Monocrystalline Diamond

Author(s)
Craig D. McGray, Richard A. Allen, Marc J. Cangemi, Jon C. Geist
Etching of monocrystalline diamond in oxygen and water vapor at 1100° C through small pores in a silicon nitride film produced smooth-walled rectangular...

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

Author(s)
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...

ThermoML is an XML-based approach for storage and exchange of experimental, predicted, and critically evaluated thermophysical and thermochemical property data...

State Discriminiation Signal Nulling Receivers

Author(s)
Francisco E. Becerra Chavez, Jingyun Fan, Gerald Baumgartner, Sergey V. Polyakov, Julius Goldhar, Jonathan Kosloski, Alan L. Migdall
Optimized state-discrimination receiver strategies for nonorthogonal states can improve the capacity of the communication channels operating with error rates...

Are Electron Tweezers Possible?

Author(s)
Vladimir P. Oleshko, James M. Howe
Positively answering the question above, we demonstrate in this work single electron beam trapping and steering of 20-100 nm solid Al nanoparticles generated...

p-Wave Cold Collisions in an Optical Lattice Clock

Author(s)
Nathan D. Lemke, Andrew D. Ludlow, J. von Stecher, Jeffrey A. Sherman, A.M. Rey, Christopher W. Oates
State-of-the-art optical clocks with neutral atoms employ an optical lattice to tightly confine the atoms, enabling high-resolution spectroscopy and the...
