Abstract :
Ultracold Fermi-Fermi mixtures offer intriguing possibilities to study fermionic pairing phenomena and superfluidity in new regimes beyond the currently employed spin mixtures of a single species. We produce a doubly-degenerate mixture of 6Li and 40K atoms by evaporative cooling in an optical dipole trap. The trapping light is provided by a 100-W fiber laser operating near a wavelength of 1070nm.
