Abstract: Using the AdS-CFT correspondence, we calculate the transport coefficients ofa strongly interacting system with a non-abelian SU2 global symmetry near asecond order phase transition. From the behavior of the poles in the Green-sfunctions near the phase transition, we determine analytically the speed ofsecond sound, the conductivity, and diffusion constants. We discusssimilarities and differences between this and other systems with vector orderparameters such as p-wave superconductors and liquid helium-3.
