该综述概述了理解非常规超导体非均匀能隙特性的相关概念，为厘清其与常规超导体的差异、能隙来源及相关矛盾研究结论提供了基础。
AI 中文摘要
能隙是超导体的关键特性之一，源于金属系统进入超导态后准粒子激发发生的剧烈变化。非常规超导体通常表现出非均匀的能隙，因此呈现出备受研究关注的物理效应。在这篇综述中，我们概述了理解非常规超导体与常规超导体差异、能隙来源及其在实验可测量中表现所需的概念，为理解当前开放研究问题及梳理近期含矛盾结论的文献提供基础。
英文摘要
The energy gap is one of the defining properties of a superconductor and appears because the quasiparticle excitations radically change once a metallic system enters the superconducting state. Unconventional superconductors typically exhibit a non-uniform gapping and therefore show physical effects that are subject to intense research. In this review, we provide an overview of concepts needed to understand how unconventional superconductors are different from conventional ones, where the gapping comes from and how it expresses itself in experimentally accessible quantities. This should give the basis to understand current open research questions and navigate the recent literature that tend to contain contradictory conclusions.
