摘要:

最近已经证实,金属中的输运弛豫速率受系统温度的限制。在这项工作中,我们讨论了过掺杂的电子掺杂的铜氧化物,我们表明构成一个明确的反例,这个假定的“普朗克”约束的运输现象,提出了严重的问题的约束的效力。

英文摘要:

It has recently been conjectured that the transport relaxation rate in metals is bounded above by the temperature of the system. In this work, 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.
