| Abstract | It has recently been conjectured that the transport relaxation rate in metals is bounded above by the temperature of the system. In this paper, we discuss the transport phenomenology of overdoped electron-doped cuprates, which we show constitute an unambiguous counterexample to this putative ``Planckian{''} bound, raising serious questions about the efficacy of the bound. |
