摘要

在过去的9年中，大量的实验证据被提出，声称证明高压下的富氢材料是高温超导体，正如传统的bcs电子-声子理论所预测的那样。在实验证据中最重要的是电阻测量，它声称表明这些材料的电阻率远远低于实验精度范围内最好的普通金属。在这里，我提出了另一种解释，报道这些材料的小电阻消失，不涉及超导性。

Electrical Resistance of Hydrides Under High Pressure: Evidence of Superconductivity or Confirmation Bias?

During the past 9 years, extensive experimental evidence has been presented that is claimed to demonstrate that hydrogen-rich materials under high pressure are high-temperature superconductors, as predicted by conventional BCS-electron–phonon theory. Foremost among the experimental evidence are electrical resistance measurements, which claimed to show that the resistivity of these materials falls well below that of the best normal metals within experimental accuracy. Here I propose an alternative explanation for the vanishingly small resistance reported for these materials that does not involve superconductivity.

期刊介绍： The Journal of Superconductivity and Novel Magnetism serves as the international forum for the most current research and ideas in these fields. This highly acclaimed journal publishes peer-reviewed original papers, conference proceedings and invited review articles that examine all aspects of the science and technology of superconductivity, including new materials, new mechanisms, basic and technological properties, new phenomena, and small- and large-scale applications. Novel magnetism, which is expanding rapidly, is also featured in the journal. The journal focuses on such areas as spintronics, magnetic semiconductors, properties of magnetic multilayers, magnetoresistive materials and structures, magnetic oxides, etc. Novel superconducting and magnetic materials are complex compounds, and the journal publishes articles related to all aspects their study, such as sample preparation, spectroscopy and transport properties as well as various applications.
