I will report on the experimental investigation of the static and dynamic properties of a fully miscible mixture of superfluids made of two gases of sodium atoms prepared in two different internal states and trapped in a single optical trap. Thanks to the favourable interaction properties and the vicinity to the miscible-immiscible phase transition we were able to observe macroscopic effects such as clean spin-dipole oscillations, large spin polarizability and spin superfluidity. I will show the experimental result together with the theoretical simulations and illustrate possible analogies with mechanisms in high-energy physics.
