Universal Planckian relaxation in the strange metal state of the cuprates

A. Shekhter, B. J. Ramshaw, M. K. Chan +1

A major puzzle in high-$T_{\mathrm{c}}$ superconductivity is the origin of the ``Planckian'' relaxation rate $1/\ddot{I}„$ underlying the linear-in-temperature resistivity in the strange-metal…
