高$T_{c}$铜氧化物超导体电子态色散的拓扑共振理论解释

Interpretation of the Dispersion of the Electron States of High-$T_{c}$ Cuprate Superconductors Based on the Theory of Topological Resonance

W. Winkler

摘要:

解释了$n_{h}\simeq\frac{1}{8}$空穴/铜体系中电子态在波腹方向的反常色散现象。在光电子激发中,对称破缺引起的$\mathbf{k}$空间的变换是实验中清楚反映的一种特殊现象。成对的光电子发射的预测,使一个新的充满活力的上移称为\emph{pair shake-up effect},这解释了实验观察到的非色散和色散行为之间的急剧转变。解释了$\mathbf{k}_{||}ε[0,\pm π/2]$反结态的消失。

英文摘要:

The unusual dispersion of electron states in antinodal direction for $n_{h}\simeq\frac{1}{8}$ holes/copper is explained. In photoelectron excitations, transformations of the $\mathbf{k}$ space as a consequence of symmetry breaking proves to be an exceptional phenomenon distinctly reflected by the experiments. Paired photoelectron emissions are predicted that enable a new energetic upward shift termed as \emph{pair shake-up effect} which explains the experimentally observed sharp transition between non-dispersive and dispersive behaviour. The disappearance of antinodal states for $\mathbf{k}_{||}ε[0,\pm π/2]$ is explained.
