چکیده

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 properties in any combination of spin states.

An interacting Fermi-Fermi mixture at the crossover of a narrow Feshbach resonance

This work describes experiments with quantum-degenerate atomic mixtures at ultracold temperatures, where quantum statistics determine macroscopic system properties. The first heteronuclear molecules at ultracold temperatures are formed in a quantum degenerate two-species Fermi-Fermi mixture on the repulsive side of a narrow s-wave Feshbach resonance. Elastic collisions in this mixture are inves...

Feshbach Resonances and Periodic Potentials in Ultracold Bose-Fermi Mixtures

This thesis investigates the possibilities to experimentally realize strongly correlated quantum systems by means of the sodium-lithium Bose-Fermi mixture. For that purpose, we have studied the intraspecies interactions of sodium as well as the interspecies interactions within the mixture. With a quantitative analysis of the sodium Feshbach spectrum, we were able to refine its scattering proper...

Tests of universal three-body physics in an ultracold bose-fermi mixture.

Recent measurements of Efimov resonances for a number of ultracold atom species have revealed an unexpected universality, in which three-body scattering properties are determined by the van der Waals length of the two-body interaction potential. To investigate whether this universality extends to heteronuclear mixtures, we measure loss rate coefficients in an ultracold trapped gas of 40K and 87...

Broad 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...

Manipulation des Interactions dans les Gaz Quantiques:

The interparticle interactions in ultracold atomic gases can be tuned using Fano–Feshbach scattering resonances, which occur in low–energy collisions between two atoms. These resonances are usually obtained using an external static magnetic field. They turn ultracold atomic gases into an experimental playground for the investigation of novel phases in which Quantum Physics plays a key role. The...
