Predissociations in the 0 u + and 1 g States of K 2

October 1, 2002
Author(s)
T Bergeman, Paul S. Julienne, Carl J. Williams, Eite Tiesinga, M R. Manaa, H Wang, P L. Gould, W C. Stwalley
Recently Wang, Gould and Stwalley showed by exciting atomic fragments that predissociation occurs in the Ig and O + u states of K2. In this study, we supplement the interpretation given in the original report with a more detaileddiscussion. The

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

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

Magnetic-Field Imaging of Weakly Bound Levels of the Ground-State Na 2 Dimer

February 1, 2002
Author(s)
T Laue, Eite Tiesinga, C Samuelis, H Knockel, E Tiemann
We measured in a molecular beam experiment the magnetic field dependence of the last bound levels of the X 1Σg + and a 3Σ +u potentials close to the 3s+3s asymptote of Na 2. The field behavior of these levels in an external magnetic field differs for even

Optimizing a Phase Gate Using Quantum Interference

February 1, 2002
Author(s)
E Charron, Eite Tiesinga, F H. Mies, Carl J. Williams
A controlled interference is proposed to reduce, by two orders of magnitude, the decoherence of a quantum gate for which the gate fidelity is limited by coupling to states other than the |0> and |1> qubit states. This phenomenon is demonstrated in an
