铁基高$T_c$超导体结的Andreev反射理论

Theory of Andreev reflection in junctions with iron-based High-$T_c$ superconductors

Jacob Linder, Asle Sudbø

摘要:

我们建立了一个理论,在正常的$\mid$超导结的低能量量子输运涉及最近发现的铁基高$T_c$超导体。在我们的方法中,我们适当地考虑了Andreev束缚表面态和复杂的费米表面拓扑结构,并研究了FeAs晶格可能的序参量对称性的签名。我们的结果有助于确定铁-磷属元素化物超导体中超导态的对称性。

英文摘要:

We construct a theory for low-energy quantum transport in normal$\mid$superconductor junctions involving the recently discovered iron-based high-$T_c$ superconductors. We properly take into account both Andreev bound surface states and the complex Fermi surface topology in our approach, and investigate the signatures of the possible order parameter symmetries for the FeAs-lattice. Our results could be helpful in determining the symmetry of the superconducting state in the iron-pnicitide superconductors.
