Thanks to a fruitful collaboration with the electronic workshop of LENS, CNR-INO and INRiM, we have developed a new low-impedance and versatile RF antenna. The innovative design is tailored for cold atoms experiments, and we successfully tested its performance with ultracold lithium atoms. Our solution combines an optimized RF coil geometry with transmission-line impedance transformer, enabling large currents to flow through the coil while keeping electromagnetic interference with surrounding equipment negligible and maintaining wide optical access. Our versatile design may serve as a new standard for generating RF fields in cold atoms experiments. F. Scazza et al. |
Fermions with tunable interactions... In the lithium lab we produce ultracold Fermi gases of 6Li to explore out-of-equilibrium dynamics and transport phenomena in strongly correlated fermionic matter. Atoms are confined into light-imprinted potential structures, simulating the motion of electrons in solid state devices. Our main goal is the study of two-dimensional strongly correlated phases, such as superfluidity across the BCS-BEC crossover and its robustness to disorder.
