我们对最近试图引入新的量子（“普朗克”）极限来解释金属中电子非弹性散射率的温度依赖性的尝试进行了批判性的回顾。我们简要地讨论了超导铜酸盐和一些类似体系中电阻率随温度线性增长（从极低温开始）的主要实验事实和一些简单的理论模型。对于这种行为，目前还没有普遍接受的理论解释。我们还讨论了已知的电导率（电阻）的量子极限。指出一些文献提出的关于非弹性松弛率的普朗克极限是一种与表示实验数据的某种程序有关的错觉。
We present a critical review of recent attempts to introduce a new quantum (‘Planckian’) limit for the temperature dependence of the inelastic scattering rate of electrons in metals. We briefly discuss the main experimental facts and some simple theoretical models explaining the linear-in-temperature growth of resistivity (starting from very low temperatures) in superconducting cuprates and some similar systems. There is no commonly accepted theoretical explanation for such behavior up to now. We also discuss the known quantum limits for electrical conductivity (resistance). It is shown that the universal Planckian limit for the inelastic relaxation rate proposed in some papers is a kind of delusion related to a certain procedure to represent the experimental data.
