Title: Signatures of electronic hydrodynamics in electrical and thermal transport

Abstract: The hydrodynamic limit is a simple, solvable limit of the transport problem in a strongly correlated electron system. I will describe the consequences of hydrodynamics on the DC electrical and thermal conductivity, highlighting three particular examples we have recently studied: (1) the consequences of potential vs. magnetic disorder on transport in viscous Fermi liquids, (2) consequences of Fermi surface geometry on transport at the ballistic-to-hydrodynamic crossover, and (3) the experimentally observed violations of the Wiedemann-Franz law in the quasirelativistic electron-hole plasma of graphene. These new theories may explain puzzling transport phenomena, including T^2 resistivity in single-band SrTiO3, and "strange metal" phases.
