非相干金属霍尔电导率的谱函数法

Spectral function method for Hall conductivity of incoherent metals

Osamu Narikiyo

摘要:

本文用电子的模型谱函数计算了Pr_{2-x} Ce_xCuO_4(PCCO)超导体正常金属态的霍尔电导率,忽略了电流的顶点修正。结果与实验定性一致。因此,费米液体理论不能解释霍尔电导率反常现象的原因就清楚了。波动-交换近似法的不一致性也变得很明显。

英文摘要:

Using a model spectral function of the electron the Hall conductivity in the normal metallic state of the Pr_{2-x}Ce_xCuO_4 (PCCO) superconductor is calculated neglecting the current vertex-correction. The result is qualitatively consistent with the experiment. Consequently the reason becomes clear why the Fermi-liquid theory fails to explain the anomaly of the Hall conductivity. The inconsistency of the fluctuation-exchange approximation also becomes clear.
