Feshbach resonances in the Li-K Fermi-Fermi mixture: elastic versus inelastic interactions
We present a detailed theoretical and experimental study of Feshbach resonances in the Li-K mixture. Particular attention is given to the inelastic scattering properties, which have not been considered before. As an important example, we thoroughly investigate both elastic and inelastic scattering properties of a resonance that occurs near 155G. Our theoretical predictions based on a coupled ch...
متن کاملExploring an ultracold fermi-fermi mixture: interspecies feshbach resonances and scattering properties of 6Li and 40K.
We report on the observation of Feshbach resonances in an ultracold mixture of two fermionic species, (6)Li and (40)K. The experimental data are interpreted using a simple asymptotic bound state model and full coupled channels calculations. This unambiguously assigns the observed resonances in terms of various s- and p-wave molecular states and fully characterizes the ground-state scattering pr...

متن کاملBroad Feshbach resonance in the 6Li-40K mixture.
We study the widths of interspecies Feshbach resonances in a mixture of the fermionic quantum gases 6Li and 40K. We develop a model to calculate the width and position of all available Feshbach resonances for a system. Using the model, we select the optimal resonance to study the {6}Li/{40}K mixture. Experimentally, we obtain the asymmetric Fano line shape of the interspecies elastic cross sect...
