Abstract

Contrary to the current consensus, I argue that the existing evidence for high-temperature superconductivity in hydrides under high pressure is compelling. I suggest that the focus of the field should urgently shift to establish unequivocally experimentally whether or not superconductivity in pressurized hydrides exists, instead of continuing to search for new materials that might show elusive signals of unproven superconductivity at ever higher temperatures. The implications of a negative finding for the theoretical understanding of superconductivity are discussed.

摘要

与当前的共识相反,我认为现有证据表明高压下氢化物中的高温超导现象令人信服。我建议该领域的重点应立即转移,通过实验明确确定加压氢化物中是否存在超导现象,而不是继续寻找可能在更高温度下显示未经证实的超导难以捉摸信号的新材料。文中还讨论了否定性发现对超导理论理解的影响。
