One of the outstanding problems in Iron pnictide research is the unambiguous detection of its pairing symmetry. The most probable candidates are the two-band and sign-reversed wave pairing. In this work the Andreev conductance and shot noise are used as a probe for the pairing symmetry of Iron pnictide superconductors. Clear differences emerge in both the zero bias differential conductance and the shot noise in the tunneling limit for the two cases enabling an effective distinction between the two.

散粒噪声作为铁氧超导体配对对称性的探针

铁肽研究中的突出问题之一是对其配对对称性的明确检测。最可能的候选者是两波段和符号反转的波对。在这项工作中，安德列夫电导率和散粒噪声被用作探测铁氧超导体的配对对称性的探针。在这两种情况下，零偏置差分电导和隧穿极限中的散粒噪声都出现了明显的差异，从而可以有效区分两者。
