Spontaneous Dissociation of Long-Range Feshbach Molecules

January 1, 2005

Author(s)

T K hler, Eite Tiesinga, Paul S. Julienne

We study the spontaneous dissociation of diatomic molecules produced in cold atomic gases via magnetic field tunable Feshbach resonances. We provide a universal formula for the lifetime of these molecules that relates their decay to the scattering length

Ultracold dimmer association induced by a far off-resonance optical lattice

E L. Bolda, Eite Tiesinga, Paul S. Julienne

Hyperfine-Changing Collisions in an Optically Trapped Gas of Ultracold Cesium and Lithium

December 17, 2004

Author(s)

M Mudrich, S Kraft, J Lange, A Mosk, M Weidemuller, Eite Tiesinga

We present measurements of the rate of hyperfine-state-changing collisions of unpolarized cesium (133Cs) andlithium (7Li) atoms confined in an optical dipole trap in the temperature range between 30 and 130 muK. Toinfer rate coefficients from trap loss

Photoassociation Spectroscopy of Cold Alkaline-Earth-Metal Atoms Near the Intercombination Line

December 1, 2004

Author(s)

R Ciurylo, Eite Tiesinga, Svetlana A. Kotochigova, Paul S. Julienne

The properties of photoassociation (PA) spectra near the intercombination line (the weak transition between 1S0 and 3P1 states) of group II atoms are theoretically investigated. As an example we have carried out a calculation for Calcium atoms colliding at

Photoassociative Formation of Ultracold Polar KRb Molecules

November 1, 2004

Author(s)

Svetlana A. Kotochigova, Eite Tiesinga, Paul S. Julienne

We investigate the effectiveness of creating polar ground state KRb molecules by two-color photoassociative spectroscopy. In this process the molecules are formed from ultra-cold samples of K and Rb. Focussing on spin-polarized atoms we show that an

Adiabatic Association of Ultracold Molecules via Magnetic Field Tunable Interactions

September 14, 2004

Author(s)

K Goral, T Koehler, S A. Gardiner, Eite Tiesinga, Paul S. Julienne

We consider in detail the situation of applying a time dependent external magnetic field to a 87Rb atomic Bose-Einstein condensate held in a harmonic trap, in order to adiabatically sweep the interatomic interactions across a Feshbach resonance to produce
