标题： Symmetry Aspects of Chiral Superconductors

摘要： 量子系统理论、合成及实验探测方面的最新进展揭示了许多适合作为手性超导体候选材料的体系。手性超导体是非传统超导体的一个子集，它破缺时间反演对称性。由于序参量的双分量性质，允许存在复数相对相位，因此可以破缺时间反演对称性。本文聚焦于讨论使得手性超导体得以发展的对称性方面因素。我们介绍了群论中的关键概念，并将其应用于超导背景下序参量分类以及朗道相变理论的推广。 显示英文摘要

摘要： Recent developments in theory, synthesis, and experimental probes of quantum systems have revealed many suitable candidate materials to host chiral superconductivity. Chiral superconductors are a subset of unconventional superconductors which break time-reversal symmetry. Time-reversal symmetry breaking is possible given the order parameter's two-component nature, allowing for a complex relative phase. In this article, we focus on discussing the underlying symmetry aspects that allow for the development of chiral superconductivity. We provide an introductory account of key concepts in group theory and apply these to the classification of order parameters and the generalization of the Landau theory of phase transitions in the context of superconductivity.
