“…There have also been applications to the generalized global symmetry reformulation of hydrodynamics [3][4][5][6]. At a more practical level the formalism has been used to analyze the physics of relativistic plasmas [7], as well as to understand the behavior of strongly coupled condensed matter systems [8][9][10][11][12][13].…”

We consider magnetohydrodynamics with an external magnetic field. We find that in general one must allow for a non-zero incoherent Hall conductivity to correctly describe the DC longitudinal and Hall thermal conductivities beyond order zero in the magnetic field expansion. We apply our result to the dyonic black hole, determining the incoherent Hall conductivity in that case, and additionally prove that the existence of this transport coefficient leads to a significantly better match between the hydrodynamic and AC thermo-electric correlators.

“…Such processes disturb mostly the entropy current, leaving the electrical transport almost unaffected [48,49]. Their abundance is characteristic for strongly correlated electron systems described, for example, as a hydrodynamic electron fluid [50,51], where the energy dissipation is dominated by small-angle electron-phonon scattering [52]. Alternatively, the electron-electron relaxation can be another source of momentum conserving collisions in the high-T c superconductors [53], whereas in FeSe it can result from the interaction of charge carriers with anisotropic spin fluctuations [54].…”

The in-plane anisotropy of the Seebeck (S) and Nernst (ν) coefficients of the nearly optimally doped cuprate superconductor La 1.86 Sr 0.14 CuO 4 was measured under uniaxial pressure. Regardless of the qualitative differences between the S(T) and ν(T) dependences, both the Seebeck and Nernst anisotropies evolve very similarly with temperature. Namely, they emerge slightly above the structural transition, then change their character, and eventually sign at the temperature close to the temperature of the pseudogap formation. We conclude that the pseudogap possibly breaks rotational symmetry and we indicate an important role played in this phase by small-angle inelastic scattering.

We discuss the attempts of fitting a number of the approximate power-law dependences observed in the cuprates into one consistent holographic or holographically inspired hydrodynamic framework. Contrary to the expectations, the goal of reproducing as many as possible of the established behaviours of the thermodynamic and transport coefficients appears to be achievable within the picture of a non-degenerate fermion fluid with quadratic dispersion. While not immediately elucidating the essential physics of the cuprates, this observation suggests a possible reason for which the previous attempts towards that goal have so far remained inconclusive.
