欠掺杂高温超导体中两个能隙态的唯象模型及短程反铁磁关联效应

Phenomenological model for two gap states in underdoped high-temperature superconductors and short-range antiferromagnetic correlation effect

T. Morinari

摘要:

在欠掺杂高温超导体中,我们假设反铁磁轨道关联来模拟赝能隙态,研究了这种关联如何区别于包含有限程反铁磁关联效应的d波超导关联。尽管这两个关联具有相同的d波对称性,但每个关联的贡献在谱权和态密度上是明显不同的。

英文摘要:

Assuming antiferromagnetic orbital correlations to model the pseudogap state in the underdoped high-temperature superconductors, we study how this correlation is distinguished from the d-wave superconductivity correlation with including the finite-range antiferromagnetic correlation effect. In spite of the fact that both correlations have the same d-wave symmetry, the contributions from each correlation is clearly distinguished in the spectral weight and the density of states.
