TLDR
It is found that the resistivity of the quantum critical metal Sr3Ru2O7 is also T-linear at the critical magnetic field of 7.9 T, and the scattering rate per kelvin is well approximated by the ratio of the Boltzmann constant to the Planck constant divided by 2π.Abstract:
Many exotic compounds, such as cuprate superconductors and heavy fermion materials, exhibit a linear in temperature (T) resistivity, the origin of which is not well understood. We found that the resistivity of the quantum critical metal Sr(3)Ru(2)O(7) is also T-linear at the critical magnetic field of 7.9 T. Using the precise existing data for the Fermi surface topography and quasiparticle velocities of Sr(3)Ru(2)O(7), we show that in the region of the T-linear resistivity, the scattering rate per kelvin is well approximated by the ratio of the Boltzmann constant to the Planck constant divided by 2π. Extending the analysis to a number of other materials reveals similar results in the T-linear region, in spite of large differences in the microscopic origins of the scattering.read more

Theory of universal incoherent metallic transport
TL;DR: A universal framework of incoherent metallic transport in which quantities are bounded could be the way forward as discussed by the authors, where linear resistivity across many strongly correlated materials at high temperatures has no satisfactory explanation.

TL;DR: In this article, the magic-angle twisted bilayer bilayer graphene has been shown to have properties that are sensitive to carrier density and to controllable environmental factors such as the proximity of nearby gates and twist-angle variation.

Evidence for hydrodynamic electron flow in PdCoO2
TL;DR: Experimental evidence that the resistance of restricted channels of the ultrapure two-dimensional metal palladium cobaltate (PdCoO2) has a large viscous contribution is reported, suggesting a role for the viscosity of the fluid in determining the resistance.

Viscosity in strongly interacting quantum field theories from black hole physics
TL;DR: It is provided evidence that this value of shear viscosity to volume density of entropy may serve as a lower bound for a wide class of systems, thus suggesting that black hole horizons are dual to the most ideal fluids.

Non-Fermi-liquid behavior in d - and f -electron metals
TL;DR: A relatively new class of materials has been found in which exhibit unusual temperature dependences in their low-temperature properties, including several examples in which the specific heat divided by temperature shows a singular $\mathrm{log}T$ temperature dependence over more than two orders of magnitude as mentioned in this paper.
