In their recent paper [Phys. Rev. A 71, 033622], B. T. Seaman et al. studied Bloch states of the condensate wave function in a Kronig-Penney potential and
Fires and second generation InSb radiometers have been developed and characterized to hold the National Institute of Standards and Technology (NIST) spectral
Wavelengths of the individual fine-structure components of the n=1-2(Ly alpha), n=1-3(Ly beta), n=1-4(Ly gamma), n=1-5(Ly delta), n=1-6(Ly epsilon), n=1-7(Ly xi
Laser cooling processes are theoretically investigated for a cascade scheme where the upper state decays more slowly than the intermediate one. A laser coupling
Absolute gravity measurements offer teh possibility of measuring vertical height changes (the subject of this meeting) at the centimeter level. Today's absolute
Accurate, reproducible measurement of radioactivity in nuclear medicine applications is vital to ensuring the safety and effectiveness of disease diagnosis and
A quantum bit is a closed two-dimensional Hilbert space, but often experimental systems have three or more energy levels. In a Josephson phase qubit the energy
Linear coupling between solid-state quantum resonators generates entanglement and squeezing effectively. We study the coupled system of a nanomechanical
Low frequency noise presents a serious source of decoherence in solid- state qubits. When combined with a continuous weak measurement of the eigenstates of a
We present our latest results on the ultrasensitive molecular overtone spectroscopy using the cavity-enhanced frequency modulation (FM) technique. The principle

Using beam-foil spectroscopy, we have observed several new lines in the B IV and B V spectra. This experimental work was combined with theoretical calculations
We have made accurate measurements near 157 nm of the relative index of refraction, its dispersion, and its temperature dependence for two grades of calcium

We observe dramatic changes in the atomic momentum distribution of a Fermo gas in the region of the BCS-BEC crossover. We study the shape of the momentum
We derive an exact propagation scheme for nonlinear Schr\o}dinger equations. This scheme is entirely analogous to the propagation of linear Schr\o}dinger

A merged-beams electron-energy-loss technique is described by which absolute cross sections can be measured for near-threshold electro-impact excitation of
Frequency dependent response characteristics of photocurrent meters using large area, radiometric quality Si photodiodes have been analyzed. The current
A method for calibrating indicating instruments that exploits the combinatorial properties of a set of different-valued, and mostly uncalibrated, artefacts is
A pedagogical overview of intramolecular vibrational redistribution (IVR) phenomena in vibrationally excited molecules is presented. In the interest of focus
Calculations and measurements of particle growth in silane RF capacitively coupled discharges are reported. The measurements of particle diameters of 8 nm to 50
Two-loop Bethe logarithms are calculated for excited P and D states in hydrogenlike systems, and estimates are presented for all states with higher angular

Charge and spin dynamics in La 2-2xSr 1+2xMn 2O 7 (x=0.4,0.5) are probed by magneto-Raman spectroscopy. A competition between charge-order, antiferromagnetic
A remarkable synergy between traditionally CW laser-based precision optical frequency metrology and mode-locked ultrafast lasers has led to precision control of
We measured the spectrum of cesium emitted by a pulsed radio-frequency discharge in the region 1550 to 40 000 using concave grating spectrographs, Fabry-Perot
Ultracold molecules have been made by applying a time-dependent magnetic field to a dilute quantum gas of ultracold trapped fermionic atoms. This raises the
