Abstract: | I will give an overview of the phenomenon of superfluidity. I will then present recent studies on anomalies in superfluids and derive Kubo formulas for the associated transport coefficients using the equilibrium partition function techniques of Minwalla and collaborators. I will also review the special features revealed in superfluid hydrodynamics when the fluid obey a Lifshitz scaling symmetry. Such behavior is expected near quantum critical points which are believed to be the cause of the exotic properties of heavy fermions compounds and high T_c superconductors. The Seminar will be based on works in collaboration with Carlos Hoyos and Yaron Oz. |
