Repeated noise pattern in the data of arXiv:1807.08572, "Evidence for Superconductivity at Ambient Temperature and Pressure in Nanostructures"
A recent preprint [arXiv:1807.08572] has reported the observation of room temperature supercondutivity in a nanostructured solid composed of gold and silver nanocrystals. Given the extraordinary and exciting nature of this claim, it is worth examining the reported data closely. In this short comment I point out a very surprising feature in the data: an identical pattern of noise for two presumably independent measurements of the magnetic susceptibility as a function of temperature.
