论文摘要

$ _2 $的CERH $ _2 $的多个$ h $ - $ t $相图提供了设计拓扑超导体的新路线。尽管弱耦合理论在定性上解释了实验相图,但它们之间的定量差异却阻止了结论性的解释。在这封信中,我们彻底研究了库仑相互作用和局部非中心对称超导体的相图的影响。我们揭示了偶尔的奇偶校验过渡和强烈相关的超导体中平价过渡场的增强,而解决了$ _2 $的CERH $ _2 $问题。

The discovery of the multiple $H$-$T$ phase diagram of CeRh$_2$As$_2$ offers a new route to designing topological superconductors. Although weak-coupling theories explain the experimental phase diagram qualitatively, a quantitative discrepancy between them has discouraged conclusive interpretation. In this Letter, we thoroughly study the effect of Coulomb interaction and the phase diagrams of locally noncentrosymmetric superconductors. We reveal even-odd parity transition and the enhancement of the parity transition field in strongly correlated superconductors, and an issue of CeRh$_2$As$_2$ is resolved.
