Loading Bose condensed atoms into the ground state of an optical lattice
P. S. Julienne, Y. B. Band, C. J. Williams +1
We optimize the turning on of a one-dimensional optical potential, V_L(x,t) = S(t) V_0 cos^2(kx) to obtain the optimal turn-on function S(t) so as to load a Bose-Einstein condensat…
Optical tuning of the scattering length of cold alkaline earth atoms
R. Ciurylo, E. Tiesinga, P. S. Julienne
It is possible to tune the scattering length for the collision of ultra-cold 1S0 ground state alkaline-earth atoms using an optical Feshbach resonance. This is achieved with a lase…
Molecular production in two-component atomic Fermi gases
Jan Chwedenczuk, Krzysztof Goral, Thorsten Koehler +1
We provide a practical approach to the molecular production via linear downward sweeps of Feshbach resonances in degenerate Fermi gases containing incoherent mixtures of two atomic…
Precise determination of Li cold collision parameters by radio-frequency spectroscopy on weakly bound molecules
M. Bartenstein, A. Altmeyer, S. Riedl +9
We employ radio-frequency spectroscopy on weakly bound Li molecules to precisely determine the molecular binding energies and the energy splittings between molecular states…
Radio-Frequency Transitions on Weakly-Bound Ultracold Molecules
Cheng Chin, Paul S. Julienne
We show that radio-frequency spectroscopy on weakly-bound molecules is a powerful and sensitive tool to probe molecular energy structure as well as atomic scattering properties. An…
Spontaneous dissociation of long-range Feshbach molecules
Thorsten Koehler, Eite Tiesinga, Paul S. Julienne
We study the spontaneous dissociation of diatomic molecules produced in cold atomic gases via magnetically tunable Feshbach resonances. We provide a universal formula for the lifet…
