The application of many body theory to a variety of strongly correlated quantum fluids.听 This includes, the electron gas, liquid 3He, 4He, 3He-4He mixtures, nuclear matter, cold atom Fermi gases, heavy fermions, exotic ferromagnetic metals and superconductors, and weak ferromagnetic metals (including the, Higgs amplitude mode). 听Most recently we have worked on: F/N junctions, non-equilibrium spin systems, Dirac materials (graphene), the ratio of viscosity/entropy in strongly correlated Fermi gases, and the thermodynamic properties of a Majorana gas.听听
