摘要
在此我们回应Svintsov和Ryzhii [arXiv:1812.03764]对我们关于石墨烯中负Landau阻尼文章 [Phys. Rev. Lett. 119, 133901 (2017)] 的关切。我们证明，由于动力学动量与正则动量之间的差异，当电子-电子相互作用占主导并迫使电子气以恒定速度运动（类似于运动介质）时，漂移电流偏置石墨烯的电导由Galilean变换支配。此外，研究表明石墨烯中的非局域效应既不妨碍负Landau阻尼，也不妨碍石墨烯平台中不稳定性的出现。

备注
On July 2019, during the 2nd proofs stage, Svintsov and Ryzhii recognized that their Eq. (2) had a mistake that led to unphysical instabilities and fixed that specific problem. Here, we critically analyze their formalism and show that the non-equilibrium distribution is used incorrectly in conjunction with the Lindhard formula
