论文摘要
由已知单元$ s $ - 波超导体连接的超级导体制成的复合环上的相敏度测量值可以明确确定其配对对称性。在带有外在$β-$ bi $ _2 $ pd和$ s $ pd和$ s $ wave nb的复合环中，当nb连接到$β-$ _2 $ _2 $ pd $ pd $ pd $ pd $ pd $ pd $ bi bi bi bi bi $ $ $ $ $ ped $ p $ p时，我们已经观察到半级量子通量。这些发现提供了三胞胎超导体$β-$ bi $ _2 $ pd的奇数配对状态的明确证据。
Phase-sensitive measurements on a composite ring made of a superconductor of interest connected by a known singlet $s$-wave superconductor can unambiguously determine its pairing symmetry. In composite rings with epitaxial $β-$Bi$_2$Pd and $s$-wave Nb, we have observed half-integer quantum flux when Nb is connected to the opposite crystalline ends of $β-$Bi$_2$Pd and integer-quantum flux when Nb is connected to the same crystalline ends of $β-$Bi$_2$Pd. These findings provide unequivocal evidence of odd-parity pairing state of the triplet superconductor $β-$Bi$_2$Pd.
