摘要

本文综述了铜高温超导体中晶格对称性破缺态的理论和实验进展。最近的实验已经为旋转破碎以及平移对称的状态提供了证据,并将在向列和条纹物理方面进行讨论。这里特别重要的是用中子和x射线散射和扫描隧穿光谱技术得到的结果。本文将回顾关于晶格对称破缺状态起源的观点,并对各种实验观察到的现象的有效模型进行总结。这些方法包括弱耦合和强耦合方法,并讨论了它们的区别和联系。实验数据表明,欠掺杂铜酸盐普遍具有单向条状有序的趋势,但随着相邻CuO2层数的增加而减弱。

Lattice symmetry breaking in cuprate superconductors: stripes, nematics, and superconductivity
This article gives an overview of both theoretical and experimental developments concerning states with lattice symmetry breaking in the cuprate high-temperature superconductors. Recent experiments have provided evidence for states with broken rotation as well as translation symmetry, and will be discussed in terms of nematic and stripe physics. Of particular importance here are results obtained using the techniques of neutron and X-ray scattering and scanning tunnelling spectroscopy. Ideas on the origin of lattice-symmetry-broken states will be reviewed, and effective models accounting for various experimentally observed phenomena will be summarized. These include both weak-coupling and strong-coupling approaches, with a discussion of their distinctions and connections. The collected experimental data indicate that the tendency toward uni-directional stripe-like ordering is common to underdoped cuprates, but becomes weaker with increasing number of adjacent CuO2 layers.
