论文摘要
旋转三重奏超导体是可携带可用于拓扑量子计算的主要结合状态的新型材料。但是，这种散装材料仍然很少见。在这里，我们回顾了将K2CR3AS3建立为具有过渡温度T_C高达6.5 K的自旋三曲线超导体的结果。我们专注于多重功能的特征，以及它与铁电磁量子关键点的精致距离，这很可能是高T_C负责的。我们触摸了超导状态的拓扑方面，并暗示它是使用有史以来最高温度的拓扑旋转三角体超导体进行技术实施的新途径。
Spin-triplet superconductors are novel materials capable of harboring Majorana bound states that can be used in topological quantum computing. However, such bulk materials are still rare. Here we review the results that established K2Cr3As3 as a spin-triplet superconductor with transition temperature T_c as high as 6.5 K. We focus on the multiple-phases feature, and its exquisite distance to a ferromagnetic quantum critical point which is likely responsible for the high T_c. We touch on the topological aspect of the superconducting state, and suggest that it is a new route to the technical implementation using a topological spin-triplet superconductor at the highest temperature ever.
