Wiedemann-Franz Law and Abrupt Change in Conductivity across the Pseudogap Critical Point of a Cuprate Superconductor
The thermal conductivity κ of the cuprate superconductor La_{1.6-x}Nd_{0.4}Sr_{x}CuO_{4} was measured down to 50 mK in seven crystals with doping from p=0.12 to p=0.24, both in the superconducting state and in the magnetic field-induced normal state. We obtain the electronic residual linear term κ_{...
