SUMMARY:Signatures of electronic hydrodynamics in electrical and thermal tr
 ansport
DESCRIPTION:Andy Lucas\, Department of Physics\, Stanford University\, Stan
 ford\, California 94305\, USA
\nA generic interacting and thermalizing cla
 ssical or quantum many-body system exhibits a hydrodynamic limit\, where a
 t late times the dynamics is entirely controlled by collective modes of lo
 cally conserved quantities. A hydrodynamic perspective gives a simple\, so
 lvable limit of the transport problem in a strongly correlated electron sy
 stem. I will describe the consequences of hydrodynamics on the DC electric
 al and thermal conductivity\, highlighting three particular examples we ha
 ve recently studied: (1) the consequences of potential vs magnetic disorde
 r on transport in viscous Fermi liquids\, (2) consequences of Fermi surfac
 e geometry on transport at the ballistic-to-hydrodynamic crossover\, and (
 3) the experimentally observed violations of the Wiedemann-Franz law in th
 e quasirelativistic electron-hole plasma of graphene. These new theories m
 ay explain puzzling transport phenomena\, including T2 resistivity in sing
 le-band SrTiO3\, and 'strange metal' phases.
