论文摘要
开发了一个三个成分的金茨堡 - 兰道理论，以了解在压力下新的超导体UTE $ _2 $中观察到的多个阶段。在临界压力附近$ p _ {\ rm cr} $ = 0.2GPA，其中所有组件都完全退化，预计将发生三个连续的超导转换。在UTE $ _2 $中实现的$ p $ - 波配对对称性的特征是非非军事和手性，因此可以自发折断时间反转对称性。
A three-component Ginzburg-Landau theory for a triplet pairing is developed to understand the observed multiple phases in a new superconductor UTe$_2$ under pressure. Near the critical pressure $P_{\rm cr}$=0.2GPa where all components are perfectly degenerate the three successive superconducting transitions are predicted to occur. The $p$-wave pairing symmetry realized in UTe$_2$ is characterized by non-unitarity and chirality with point nodes, thus time reversal symmetry spontaneously broken.
