摘要

高温铜超导体赝隙相的物理性质在过去的30年里一直是一个谜。在欠掺杂铜酸盐中普遍存在的赝隙相表明，理解它是揭示高温超导起源的关键。我们回顾了这个问题的各种理论方法，强调了这些化合物的欠掺杂区域的涌现对称性的概念。我们通过考虑与这些材料丰富的现象学相关的几个基本问题来区分这些理论。最后，我们讨论了最近关于两种纠缠的预成形对的想法，它们通过特定的希格斯机制在赝隙起始温度T*处打开一个间隙。我们回顾一下这一思路的实验结果。

Fluctuations and the Higgs Mechanism in Underdoped Cuprates

The physics of the pseudogap phase of high-temperature cuprate superconductors has been an enduring mystery over the past 30 years. The ubiquitous presence of the pseudogap phase in underdoped cuprates suggests that understanding it is key to unraveling the origin of high-temperature superconductivity. We review various theoretical approaches to this problem, emphasizing the concept of emergent symmetries in the underdoped region of those compounds. We differentiate these theories by considering a few fundamental questions related to the rich phenomenology of these materials. Lastly, we discuss a recent idea regarding two kinds of entangled preformed pairs that open a gap at the pseudogap onset temperature, T*, through a specific Higgs mechanism. We review the experimental consequences of this line of thought.
