摘要在固体材料中，非平凡的拓扑态、电子相关性和磁性是实现量子特性的核心要素，包括非常规超导性、电荷和自旋密度波以及量子自旋液体。由共享角三角形组成的戈薇晶格可以同时容纳这三种成分，并已被证明是研究各种量子现象（包括这些成分相互作用产生的量子现象）的肥沃平台。这篇综述介绍了戈薇晶格的基本性质，并讨论了在几种材料系统中观察到的复杂现象，包括一些戈薇金属中电荷顺序和超导性的交织、一些戈薇磁体中磁性和拓扑的调制，以及“呼吸”戈薇绝缘体中对称破缺和莫特物理的结合。该评论还强调了该领域的悬而未决的问题以及戈薇系统的未来研究方向。
AbstractsIn solid materials, non-trivial topological states, electron correlations and magnetism are central ingredients for realizing quantum properties, including unconventional superconductivity, charge and spin density waves and quantum spin liquids. The kagome lattice, made up of corner-sharing triangles, can host these three ingredients simultaneously and has proved to be a fertile platform for studying diverse quantum phenomena including those stemming from the interplay of these ingredients. This Review introduces the fundamental properties of the kagome lattice and discusses the complex phenomena observed in several materials systems, including the intertwining of charge order and superconductivity in some kagome metals, the modulation of magnetism and topology in some kagome magnets, and the combination of symmetry breaking and Mott physics in ‘breathing’ kagome insulators. The Review also highlights open questions in the field and future research directions in kagome systems.
