Hydrodynamic description of transport in strongly correlated electron systems

arXiv:1011.3068 · doi:10.1103/PhysRevLett.106.256804

Abstract

We develop a hydrodynamic description of the resistivity and magnetoresistance of an electron liquid in a smooth disorder potential. This approach is valid when the electron-electron scattering length is sufficiently short. In a broad range of temperatures, the dissipation is dominated by heat fluxes in the electron fluid, and the resistivity is inversely proportional to the thermal conductivity, . This is in striking contrast with the Stokes flow, in which the resistance is independent of and proportional to the fluid viscosity. We also identify a new hydrodynamic mechanism of spin magnetoresistance.
