欠掺杂铜氧化物中反常赝能隙相的唯象理论

A Phenomenological Theory of the Anomalous Pseudogap Phase in Underdoped Cuprates

T. M. Rice, Kai-Yu Yang, F. C. Zhang

摘要:

对铜氧化物相图欠掺杂区赝能隙相反常性质的理论描述滞后于光谱和其他实验的进展。Yang,Rice和Zhang [Phys. Rev. B 73(2006),174501]提出了一种基于低维系统弱耦合下Mott局域化方法的唯象分析方法。这篇论文成功地描述了一系列实验。这一假设的动机进行了描述和比较实验进行了审查。一个更微观的理论的影响进行了讨论,直接从微观强耦合哈密顿理论的关系。

英文摘要:

The theoretical description of the anomalous properties of the pseudogap phase in the underdoped region of the cuprate phase diagram lags behind the progress in spectroscopic and other experiments. A phenomenological ansatz, based on analogies to the approach to Mott localization at weak coupling in lower dimensional systems, has been proposed by Yang, Rice and Zhang [Phys. Rev. B 73 (2006),174501]. This ansatz has had success in describing a range of experiments. The motivation underlying this ansatz is described and the comparisons to experiment are reviewed. Implications for a more microscopic theory are discussed together with the relation to theories that start directly from microscopic strongly coupled Hamiltonians.
