论文摘要
我们研究了拓扑超导体PBTase $ _2 $的超导差距函数。特定热量的温度，磁场和三维（3D）场角依赖性证明PBTase $ _2 $的超导性完全束缚，并带有两个各向同性$ S $波差。通过系统地通过H $^+$ - 辐照系统增加非磁性疾病来探测搭配效应。发现超导过渡温度$ t _ {\ rm {c}} $，发现对疾病具有鲁棒性，这表明配对应保存签名而不是签名。
We investigate the superconducting gap function of topological superconductor PbTaSe$_2$. Temperature, magnetic field, and three-dimensional (3D) field-angle dependences of the specific heat prove that the superconductivity of PbTaSe$_2$ is fully-gapped, with two isotropic $s$-wave gaps. The pair-breaking effect is probed by systematically increasing non-magnetic disorders through H$^+$-irradiations. The superconducting transition temperature, $T_{\rm{c}}$, is found to be robust against disorders, which suggests that the pairing should be sign-preserved rather than sign-reversed.
