Repeated noise pattern in the data of arXiv:1807.08572, "Evidence for Superconductivity at Ambient Temperature and Pressure in Nanostructures"

Brian Skinner

Abstract

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.

  1. Either This Data Is Incorrect or These Physicists Just Changed the World 1 comment

    • Hasn’t this report already been debunked or is it a different one? (Edit: it is, and it shows evidence of data duplication and manipulation: https://arxiv.org/abs/1808.02929)

  2. Fraud in superconductor physics 1 comment

    • The comment by Brian Skinner who discovered the correlated noise in a graph is available on Arxiv [1]. It's not claiming fraud but points out that such an effect of correlated noise below a threshold temperature between seemingly independent measurements has not been observed…
