We present the theory of thermoelectric transport in metals with long-lived quasiparticles, carefully addressing the interplay of electron-electron scattering as well as electron-impurity scattering, but neglecting electron-phonon scattering. In Fermi liquids with a large Fermi surface and weak electron-impurity scattering, we provide universal and simple formulas for the behavior of the thermoelectric conductivities across the ballistic-to-hydrodynamic crossover. In this regime, the electrical… 
Role of electron-electron collisions for charge and heat transport at intermediate temperatures
Electric, thermal and thermoelectric transport in correlated electron systems probe different aspects of the many-body dynamics, and thus provide complementary information. These are well studied in

It is well known that the electronic thermal conductivity of clean compensated semimetals can be greatly enhanced over the electric conductivity by the availability of an ambipolar mechanism of
Departure from the Wiedemann–Franz law in WP2 driven by mismatch in T-square resistivity prefactors
The Wiedemann–Franz law establishes a link between heat and charge transport due to electrons in solids. The extent of its validity in the presence of inelastic scattering is a question raised in

Hydrodynamic behavior in electronic systems is commonly accepted to be associated with extremely clean samples such that electron–electron collisions dominate and total momentum is conserved.

TLDR
By tuning the temperature, an electronic analog of the Stokes flow around a disc immersed in a two-dimensional viscous liquid is studied and the transport signatures of the ballistic and hydrodynamic regimes on the length scale of disc size are observed.

Violation of the Wiedemann-Franz Law in Hydrodynamic Electron Liquids.
TLDR
It is shown that at low temperature 1/τ(th)(ee) is 8/5 of the quasiparticle decay rate; remarkably, the same result is found in doped graphene and in conventional electron liquids in parabolic bands.

Resistivity bound for hydrodynamic bad metals
TLDR
A rigorous upper bound on the resistivity ρ of an electron fluid whose electronic mean free path is short compared with the scale of spatial inhomogeneities is obtained, which allows phonon contributions to diffusion constants, including thermal diffusion, to directly affect the electrical resistivity.
