Length and Dimensional Measurement at NIST

Author(s)
Dennis A. Swyt
This paper reports on the past, present, and future of length and dimensional measurements at NIST. It covers the evolution of the SI unit of length through its...

An Optical Clock Based on a Single Trapped Hg+ Ion

Author(s)
Scott A. Diddams, T Udem, K R. Vogel, Christopher W. Oates, E A. Curtis, W D. Lee, Wayne M. Itano, Robert E. Drullinger, James C. Bergquist, Leo W. Hollberg
Microwave atomic clocks have been the de facto standards for precision time and frequency metrology over the past 50 years, finding widespread use in basic...

Decoherence-Free Quantum Memory Using Trapped Ions

Author(s)
D Kielpinski, V Meyer, M A. Rowe, C A. Sackett, Wayne M. Itano, C Monroe, David J. Wineland
We demonstrate a decoherence-free quantum memory of one qubit. By encoding the qubit into the decoherence-free subspace (DFS) of a pair of trapped 9Be+ ions, we...

Newton's Rings in Near-Field Optics

Author(s)
Lori S. Goldner, Jeeseong Hwang, Garnett W. Bryant, Michael J. Fasolka, P Absil, J V. Hryniewicz, F G. Johnson, H Shen, P T. Ho
We show how Newton's rings manifest themselves in near-field scanning optical microscopy and discuss how this effect can be used with topographic imaging to...

Author(s)
Talapady N. Bhat, P E. Bourne, Z. Feng, G L. Gilliland, Sanjay Jain, Veerasamy Ravichandran, B. Schneider, K. Schneider, N Thanki, H Weissig, J Westbrook, H M. Berman
The Protein Data Bank (PDB; http://www.rcsb.org/pdb/) is the single worldwide archive of structural data of biological macromolecules. This paper describes the...

Scaling Issues in the Measurement of Monolayer Films

Author(s)
Stephen M. Hsu, P M. McGuiggan, J Zhang, Y L. Wang, F Yin, Y P. Yeh, Richard S. Gates
An atomic force microscope (AFM), a surface forces apparatus (SFA), and a ball-on-inclined plane (BOIP) apparatus were used to measure the mechanical properties...
