论文摘要
在各种“奇怪”金属中，电子经历了普兰克耗散，这是一种强大而异常的散射，随温度线性生长，与金属的标准理论所期望的二次温度依赖性相反。在某些铜岩和pnictides中，电阻率对磁场的线性依赖性也被认为是异常的 - 可能是普朗克散发的附加方面。在这里，我们表明，在磁场中，在各个方面 - 田间强度，田间方向，温度和混乱水平，库酸酯奇怪金属ND -LSCO和LSCO的电阻率与标准的电子运动理论一致。发现线性场依赖性仅仅是散射速率各向异性的结果。我们得出的结论是，普朗克耗散的温度依赖性异常，但在其领域依赖性方面却不是异常的。这些丘疹的散射速率不取决于田地，这意味着他们的普兰克耗散对至少85吨的田地很强。
In various "strange" metals, electrons undergo Planckian dissipation, a strong and anomalous scattering that grows linearly with temperature, in contrast to the quadratic temperature dependence expected from the standard theory of metals. In some cuprates and pnictides, a linear dependence of the resistivity on magnetic field has also been considered anomalous - possibly an additional facet of Planckian dissipation. Here we show that the resistivity of the cuprate strange metals Nd-LSCO and LSCO is quantitatively consistent with the standard Boltzmann theory of electron motion in a magnetic field, in all aspects - field strength, field direction, temperature, and disorder level. The linear field dependence is found to be simply the consequence of scattering rate anisotropy. We conclude that Planckian dissipation is anomalous in its temperature dependence but not in its field dependence. The scattering rate in these cuprates does not depend on field, which means their Planckian dissipation is robust against fields up to at least 85 T.
