Nonexponential

January 1, 2000
Author(s)
M Kuno, D P. Fromm, H F. Hamann, A Gallagher, David Nesbitt

Nucleation of Vortez Arrays in Rotating Anisotropic Bose-Einstein Condensates

January 1, 2000
Author(s)
D L. Feder, Charles W. Clark, B I. Schneider
The nucleation of vortices and the resulting structures of vortex arrays in dilute, trapped, zero-temperature Bose-Einstein condensates are investigated numerically. Vortices are generated by rotating a three-dimensional, anisotropic harmonic atom trap

On the Properties of Alpha/Alpha + Beta Diffusion Couples

January 1, 2000
Author(s)
William J. Boettinger, Sam R. Coriell, Carelyn E. Campbell, Geoffrey B. McFadden
The properties of diffusion couples in a ternary system are examined theoretically when one end member is composed of single-phase material (alpha) and the other end member is composed of two-phase material (α + Β). Using the model of Morral and co-workers

Optical Fiber Power Measurements

January 1, 2000
Author(s)
Igor Vayshenker, Xiaoyu X. Li, David J. Livigni, Thomas Scott
We describe NIST measurement services for the calibration of optical fiber power meters. To augment the absolute power measurements NIST provides nonlinearity, spectral responsivity, and uniformity measurements. We explain the measurement standards

Optical Properties of Materials: A Sampling of NIST Contributions

January 1, 2000
Author(s)
Thomas A. Germer, R Gupta, Leonard M. Hanssen, Eric L. Shirley
Optics has found an extremely wide range of applications in industry and science, and the properties of the materials that make up optical instruments are key to their performance. Examples include glass for optical instrumentation such as telescopes and
