Designing Neutral-Atom Nanotraps With Integrated Optical Waveguides

April 1, 2002
Author(s)
J P. Burke, S G. Chu, Garnett W. Bryant, Carl J. Williams, Paul S. Julienne
Integrated optical structures offer the intriguing potential of compact, reproducible waveguide arrays, rings, Y-junctions, etc, that could be used to design evanescent field traps to transport, store, and interact atoms in networks as complicated as any

Quantum Effects on Curve Crossing in a Bose-Einstein Condensate

April 1, 2002
Author(s)
V Yurovsky, A Ben-Reuven, Paul S. Julienne
Formation of Atomic Pairs by dissociation of a molecular condensate or by inelastic collisions in an atomic condensate due to time-dependent curve crossing is studied beyond the mean-field approximation. The number of atoms formed by the spontaneous

Scattering Length of the Ground-State Mg+Mg Collision

April 1, 2002
Author(s)
Eite Tiesinga, Svetlana A. Kotochigova, Paul S. Julienne
We have constructed the $XA I \Sigma_g^+ $ potential for the collision between two ground state Mg atoms andanalyzed the effect of uncertainties in the shape of the potential on scattering properties at ultra-cold temperatures.This potential reproduces the

Photoassociation of Sodium in a Bose-Einstein Condensate

March 1, 2002
Author(s)
C R. McKenzie, J Denschlag, H Heffner, A Browaeys, L E. de Araujo, F K. Fatemi, Kevin Jones, J E. Simsarian, D Cho, A Simoni, Eite Tiesinga, Paul S. Julienne, Kristian Helmerson, Paul D. Lett, S L. Rolston, William D. Phillips
We report on the formation of ultra-cold Na2 molecules using single-photon photoassociation of a Bose-Einstein condensate. The photoassociation rate, linewidth and light shift of the J = 1, v = 135 vibrational level of the A^1)Sigma^+_u molecular bound

Quantum Encounters of the Cold Kind

March 1, 2002
Author(s)
K Burnett, Paul S. Julienne, Paul D. Lett, Eite Tiesinga, Carl J. Williams
Ultra cold atomic collisions have a broad impact in experimental and theoretical atomic physics. These encounters occur in a domain where the quantum mechanical aspects of the interacting particles are manifest, since the de Broglie wavelength is enormous
