A miniature Fouier transform (FT0 spectrometer was evaluated as a device for remotely measuring the temperature of a high stability/emissivity blackbody. The
We describe a procedure for creating pairs of condensates with appreciable relative number squeezing. We show that our procedure is relatively robust against
Laboratory Experiments refers generally to active spaceborne experiments as opposed to the equally important passive observation in space of signals coming from
rth climate modeling and global impacts of particles and gases in the atmosphere are some of the studies that benefit from the use of spectroradiometers
Recently, quantized versions of random walks have been explored as effective elements for quantum algorithms. In the simplest case of one dimension, the theory
We discuss the application of the Discrete Variable Representation to Schr dinger problems which involve singular Hamiltonians. Unlike recent authors who invoke
We introduce a novel broadband optical frequency comb generator consisting of a parametric oscillator with an intracavity electro-optic phase modulator. The
The irradiance diffraction profile of a straight edge is given as a Taylor series in powers of the distance from the geometrical shadow boundary to any point in
Surface effects significantly influence the functionality of semiconductor nanocrystals. A theoretical understanding of these effects requires an atomic-scale
The impact of the Guide to Expression of Uncertainty in Measurement is spreading from the national measurement institutes to the industrial measurement

The millimeter and submillimeter-wave molecular-beam spectrum of the perdeuterated ammonia dimer (ND3)2 has been measured between approximately 50 GHz and 400
Atomic-scale effects on electronic coupling in coupled quantum dots are studied. The empirical tight-binding approach is used to obtain the electronic structure
We observed the spectrum of neutral krypton (Kr I) in its naturally occurring isotopic mixture as emitted by a microwave-excited electrodeless discharge lamp
A new theoretical approach for treating the synchrotron radiation is applied to the case of a relativistic charged particle accelerated by a confined and
A Raman-scattering investigation of the double-layer manganites, La 2-2rSr 1+2rMn 2O 7 (x= 0.4,0.5), revealed signatures of a ) charge stripe formation and
Insrument capabilities have evolved over the past 40 or so years to the point where, today, both relative and absolute measurements can nowbe made. at the parts
We discuss the application of the Discrete Variable Representation to Schr dinger problems which involve singular Hamiltonians. Unlike recent authors which

In this letter we discuss the insecurity with present implementations of the Ekert protocol for quantum-key distribution based on the Wigner Inequality. We
NIST scientists participate in a variety of nanotechnology activities, several of which are summarized here. The drive toward both ever-smaller integrated
X-ray analytical methods with high angular resolution are becoming increasingly important for the characterization of materials used in ULSI fabrication

A comparison of spectral diffuse reflectance between different national standards laboratories is being planned under the direction of the Comit* Consultatif de
The divergent perturbation series for the LoSurdo--Stark effect has purely real coefficients. By contrast, the energy eigenvalue of the quasistationary states
The calculational methods in atomic structure are currently capable of providing the level of accuracy close to that of the most precise experiments. The
