a Thermal conductivity, κ as a function of temperature. b The scattering time τκ extracted from the same data and specific heat, times the square of temperature, T2. Contrary to what is expected in the standard Fermi liquid theory, τκT2 is never constant. The figures are from Ref. 17. The horizontal red solid line in a represents what is expected for a classical liquid according to Bridgman’s formula. Reproduced with the permission from the American Physical Society.
