Comment on arXiv:1105.6233 entitled "Neutron-Inelastic-Scattering Peak by Dissipationless Mechanism in the s++-wave State in Iron-based Superconductors" by S. Onari and H. Kontani
摘要：
最近，Onari和Kontani提交了一篇论文[arXiv：1105.6233]，批评了我们最近关于中子散射实验作为确定铁磷属元素化物中超导能隙的探针的理论研究[arXiv：1103.0586]。在他们的论文中，Onari和Kontani发展了一种形式，其中超导状态下的动态自旋磁化率的虚部（Im $χ_s(\Vec{q},ω)$）可以更准确地计算，特别是在$ω<2Δ$状态下，其中$Δ$是超导能隙。在他们论文的第IIIC节中，他们提到我们论文的结论是“基于不准确的数值计算的不正确”。在本评论中，我们表明这实际上是不正确的。
英文摘要：
Recently, Onari and Kontani submitted a paper [arXiv:1105.6233] which criticizes our recent theoretical study [arXiv:1103.0586] on the neutron scattering experiment as a probe for determining the superconducting gap in the iron pnictides. In their paper, Onari and Kontani have developed a formalism in which the imaginary part of the dynamical spin susceptibility (Im$χ_s(\Vec{q},ω)$) in the superconducting state can be more accurately calculated especially in the $ω<2Δ$ regime, where $Δ$ is the superconducting gap. In section IIIC of their paper, they mention that the conclusions of our paper are "incorrect based on inaccurate numerical calculation". In the present Comment, we show that this in fact is not correct.
