Abstract

Dan Shechtman's discovery of quasicrystals in 1982 introduced the scientific world to aperiodic crystals with unique rotational symmetries, redefining traditional crystallography. Although superconductivity in related periodic approximants has since been observed, true bulk superconductivity in quasicrystals was confirmed only in 2018. This recent discovery opens a new horizon not only for the study of correlated quasicrystals but more generally for the study of superconductivity with nontrivial spatial order. The theoretical understanding of superconducting quasicrystals poses challenges due to their lack of periodicity. Notably, they exhibit non‐BCS type superconductivity and distinct electromagnetic responses, reminiscent of the so‐called FFLO state. In this review, we provide an overview of superconducting quasicrystals, along with some “behind‐the‐scenes” information.

超导准晶体

丹-谢赫特曼（Dan Shechtman）于 1982 年发现了准晶体，向科学界介绍了具有独特旋转对称性的非周期性晶体，重新定义了传统晶体学。尽管此后在相关周期近似物中观测到了超导性，但直到 2018 年才证实了准晶体中真正的体超导性。这一最新发现不仅为相关准晶体的研究开辟了新天地，也为具有非偶数空间顺序的超导研究开辟了更广阔的天地。由于缺乏周期性，对超导准晶体的理论理解面临挑战。值得注意的是，它们表现出非 BCS 型超导性和独特的电磁响应，让人联想到所谓的 FFLO 状态。在这篇综述中，我们将概述超导准晶体，并提供一些 "幕后 "信息。

期刊介绍： The fledgling State of Israel began to publish its scientific activity in 1951 under the general heading of Bulletin of the Research Council of Israel, which quickly split into sections to accommodate various fields in the growing academic community. In 1963, the Bulletin ceased publication and independent journals were born, with Section A becoming the new Israel Journal of Chemistry. The Israel Journal of Chemistry is the official journal of the Israel Chemical Society. Effective from Volume 50 (2010) it is published by Wiley-VCH. The Israel Journal of Chemistry is an international and peer-reviewed publication forum for Special Issues on timely research topics in all fields of chemistry: from biochemistry through organic and inorganic chemistry to polymer, physical and theoretical chemistry, including all interdisciplinary topics. Each topical issue is edited by one or several Guest Editors and primarily contains invited Review articles. Communications and Full Papers may be published occasionally, if they fit with the quality standards of the journal. The publication language is English and the journal is published twelve times a year.
