We present the design, implementation and characterization of a dual-species magneto-optical trap (MOT) for fermionic Li and K atoms with large atom numbers. The MOT simultaneously contains 5.2 × 10 Li-atoms and 8.0 × 10 K-atoms, which are continuously loaded by a Zeeman slower for Li and a 2D-MOT for K. The atom sources induce capture rates of 1.2 × 10… (More)
This thesis reports on the construction of a new experimental apparatus aiming to study, at ultracold temperatures, a quantum degenerate gas mixture of two different atomic species of fermionic nature: Li and K. A detailed description of the design and implementation as well as a characterization of the apparatus is presented. We have realized a very large… (More)
By releasing ultra-cold atoms from a small red detuned Gaussian trap to an optical wedge billiard we reduce the energy broadening of the atoms and perform spatial selection on the initial occupied phase space.
Loschmidt echo of atoms trapped in atom optics billiards with chaotic and mixed dynamics is realized by performing a microwave Ramsey sequence to their internal state.
