论文摘要
在过去的六年中，在高压下，在多种富含氢的化合物中，高温下的超导性。如详细计算所示，根据常规的超导性理论，这些材料中应该存在高温超导性。但是，在这里我们认为实验观察结果排除了这些材料中常规超导性。我们的结果表明，要么这些材料是一种新型的非常规的超导体，因此我们称其为“非标准超导体”，或者它们不是超导体。如果前者，我们指出，这些材料中的临界电流应比标准超导体大的五个数量级，这有可能为重要的技术应用开辟道路。如果我们认为后者更有可能，我们建议将其解释为超导性的信号要么是实验性伪像，要么是其他有趣的物理学，而不是超导性。
Over the past six years, superconductivity at high temperatures has been reported in a variety of hydrogen-rich compounds under high pressure. That high-temperature superconductivity should exist in these materials is expected according to the conventional theory of superconductivity, as shown by detailed calculations. However here we argue that experimental observations rule out conventional superconductivity in these materials. Our results indicate that either these materials are unconventional superconductors of a novel kind, which we term `nonstandard superconductors', or alternatively that they are not superconductors. If the former, we point out that the critical current in these materials should be five orders of magnitude larger than in standard superconductors, potentially opening up the way to important technological applications. If the latter, which we believe is more likely, we suggest that the signals interpreted as superconductivity are either experimental artifacts or they signal other interesting physics but not superconductivity.
