Prediction of Feshbach resonances from three input parameters
Thomas M. Hanna, Eite Tiesinga, Paul S. Julienne
We have developed a model of Feshbach resonances in gases of ultracold alkali metal atoms using the ideas of multichannel quantum defect theory. Our model requires just three param…
Quantum Phase Transitions and Continuous Observation of Spinor Dynamics in an Antiferromagnetic Condensate
Yingmei Liu, Sebastian Jung, Stephen E. Maxwell +3
Condensates of spin-1 sodium display rich spin dynamics due to the antiferromagnetic nature of the interactions in this system. We use Faraday rotation spectroscopy to make a conti…
A Bose-Einstein Condensate in a Uniform Light-induced Vector Potential
Y. -J. Lin, R. L. Compton, A. R. Perry +3
We use a two-photon dressing field to create an effective vector gauge potential for Bose-condensed Rb atoms in the F=1 hyperfine ground state. The dressed states in this Raman fie…
Heteronuclear molecules in an optical dipole trap
J. J. Zirbel, K. -K. Ni, S. Ospelkaus +6
We report on the creation and characterization of heteronuclear KRb Feshbach molecules in an optical dipole trap. Starting from an ultracold gas mixture of K-40 and Rb-87 atoms, we…
Spin-orbit coupled Bose-Einstein condensates
Tudor Stanescu, Brandon Anderson, Victor Galitski
We consider a many-body system of pseudo-spin-1/2 bosons with spin-orbit interactions, which couple the momentum and the internal pseudo-spin degree of freedom created by spatially…
Exploring an ultracold Fermi-Fermi mixture: Interspecies Feshbach resonances and scattering properties of 6Li and 40K
E. Wille, F. M. Spiegelhalder, G. Kerner +10
We report on the observation of Feshbach resonances in an ultracold mixture of two fermionic species, 6Li and 40K. The experimental data are interpreted using a simple asymptotic b…
