Spin and Density Modes in a Binary Fluid of Light

Author(s): Clara Piekarski, Nicolas Cherroret, Tangui Aladjidi, and Quentin Glorieux We report the experimental observation of spin and density modes in a binary mixture of superfluids of light. A miscible Bose-Bose mixture with repulsive interactions is realized by propagating the two circular polarization components of a laser through a nonlinear hot atomic vapor in the paraxial l… [Phys.
