Nanofabricated atom optics: Atom chips
Journal of Modern Optics, 2000Small tight trapping and guiding potentials can be created for neutral atoms moving microns above surfaces patterned with nanofabricated charged and current-carrying structures.

Abstract Atomic collisions are normal1y termed elastic or inelastic. The former lead simply to momentt1m transfer between the collision partners, or equivalently to a change in the direction of their motions; the latter lead also to a simultaneous transfer of energy between internal motion and translation.

Atomic spectrometry update. Atomic mass spectrometry
Journal of Analytical Atomic Spectrometry, 2006The review this year is dominated by the large number of publications on AMS, ICP-MS and SIMS. The increasing number of new AMS installations bears witness to the increasing interest in the technique now that smaller and simpler systems are becoming more widely available.

ATOMIC CLOCKS AND COLD ATOM SCATTERING
Laser Spectroscopy, 2002We demonstrate a Rb fountain clock which has a small cold collision shift that is cancelled by detuning the microwave cavity. To further enhance the stability and accuracy, we are currently developing a new state detection technique that directly measures population differences and are juggling atoms in the fountain. Fountain clocks also enable a novel

Equilibrium atomic structure: Rotating atoms
Physical Review Letters, 1986Exact rigid body solutions for two-electron atoms have been derived within classical mechanics. These solutions describe equilibrium constellations of the electrons, i.e. the electrons do not experience any force within these constellations. Moreover it is shown that exactly two nondegenerate equilibria exist.

Up to this point, we have only alluded to the effect that the interactions between identical atoms have on the spectral properties. In many cases, these inter-particle interactions are negligible. However, if the atoms are separated by less than the transition wavelength \(\lambda \), resonant dipole-dipole interactions become important.

Atom optics, guided atoms, and atom interferometry
2005Publisher Summary This chapter discusses the applicability of micro-optical elements for the preparation and manipulation of atomic samples. This development is in many respects complementary to the use of miniaturized magnetic traps, so called atom chips.
