金属中的普朗克弛豫错觉

Planckian relaxation delusion in metals

M. V. Sadovskii

摘要:

我们提出了一个批判性的审查最近试图引入新的量子(“普朗克”)限制的温度依赖性的电子在金属中的非弹性散射率。本文简要地讨论了超导铜氧化物和一些类似系统中电阻率随温度线性增长的主要实验事实和一些简单的理论模型。迄今为止,对这种行为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。指出某些文献中提出的非弹性弛豫率的普适普朗克极限是一种与某种方法有关的错觉。

英文摘要:

We present a critical review of recent attempts to introduce the new quantum ("Planckian") limit for the temperature dependence of 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 of 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.
