Quantum Gates Using Motional States in an Optical Lattice

June 1, 2001
Author(s)
E Charron, Eite Tiesinga, F H. Mies, Carl J. Williams
We Study an implementation of a two-qubit universal quantum gate with neutral 87Rb atoms trapped in a far-detuned two-color optical lattice. The qubit states and represent the ground and first excited motional states of an atom in a laser induced potential

Relativistic Valence Bond Theory and Its Application to Metastable Xe 2

February 1, 2001
Author(s)
Svetlana A. Kotochigova, Eite Tiesinga, I Tupitsyn
We present a new version of the relativistic configuration interaction valence bond (RCIVB) method. It is designed to perform an ab initio all-electron relativistic electronic structure calculation for diatomic molecules. A nonorthogonal basis set is

Cold Atomic Collisions Studied by Molecular Spectroscopy

January 1, 2001
Author(s)
C Samuelis, Eite Tiesinga, T Laue, M Elbs, H Knockel, E Tiemann
We observe bound states just below the dissociation limit and shape and Feshback resonances between the ground state hyperfine asymtotes by Raman spectroscopy on a molecular beam of sodium dimers. The rotational selectivity of a two-photon transition gives

Ground State Scattering Lengths for Potassium Isotopes Determined by Double-Resonance Photoassociative Spectroscopy of Ultracold 39 K

November 1, 2000
Author(s)
Haonan Wang, A N. Nikolov, J R. Ensher, P L. Gould, E E. Eyler, W C. Stwalley, J P. Burke, J L. Bohn, C H. Greene, Eite Tiesinga, Carl J. Williams, Paul S. Julienne
We use double-resonance photoassociative spectroscopy of ultracold 39K atoms to precisely determine the triplet a 3Σ scattering length for the various isotopes of potassium. Photoassociation of free 39K atoms to the pure long-range 0 (v' = O, J' = 2) level

Interacting Atoms Under Strong Quantum Confinement

June 1, 2000
Author(s)
Eite Tiesinga, Carl J. Williams, F H. Mies, Paul S. Julienne
We calculate the energy level shifts of a tightly-confined trapped alkali atom in the presence of a second trapped atom. A complete microscopic description of the interaction energy between the two atoms is used. This allows us to study tightly-confined
