论文摘要
在最近的手稿物理中。莱特牧师。 127，197001（2021）Puviani等。声称希格斯模式在对称$ a_ {1g} $ cuprates的对称性$ a_ {1g} $ raman通道中增强了拉曼响应。在这里，我们报告了一系列的技术错误，使这一结论完全无效。特别是，拉曼响应函数包含两个重新归一化的顶点，其图表清楚地覆盖了HIGGS模式贡献的图表和不受控制的结果。
In a recent manuscript Phys. Rev. Lett. 127, 197001 (2021) Puviani et al. claim that the Higgs mode gives an enhancement of the Raman response in the symmetric $A_{1g}$ Raman channel of cuprates. Here we report a series of technical mistakes in their derivation that completely invalidate this conclusion. In particular, the Raman response function contains two renormalized vertices, with a clearly overcounting of diagrams and uncontrolled results for the Higgs-mode contribution.
