Compounds called nickelates can conduct electricity without resistance well above absolute zero and at ambient pressure.

The research team co-led by Xue Qikun, an academician from the Chinese Academy of Sciences and president of Southern University of Science and Technology (SUSTech) and Chen Zhuoyu, associate professor from the Department of Physics of SUSTech, has enabled nickel oxides, one of the promising candidates for high-temperature superconductors, to achieve superconductivity under ambient pressure and at temperatures above -233 C, a milestone that scientists have pursued since superconductivity was first discovered in 1911.

A joint research team from Southern University of Science and Technology (SUSTech) and other Chinese institutions has developed a new type of high-temperature superconductors at ambient pressure, achieving a breakthrough in superconductivity research.

Angle-resolved photoemission spectroscopy reveals stronger-than-predicted attraction between charges in an unconventional superconductor.

高温超导微观机理被视为凝聚态物理“皇冠上的明珠”，在过去30多年时间里涌现出诸多杰出研究工作，但迄今仍被专业人士认为处于盲人摸象阶段。今天，《赛先生》推荐刚刚发表的《科学》杂志论文作者陈卓昱、王耀撰写的科普文章，解读他们在高温超导微观机理取得的一项新突破，展示了研究背后的思路。这一工作被视为在现有理论模型上的一次重要改进，虽然尚未能摸得全象，但也许这次新突破摸到了象鼻子，令人期待。

哈伯德模型加上这个电子间的强相互吸引力，或许可以成为解释铜氧化物超导体的完整理论模型。

The scientists said it's likely that this strong nearest-neighbor attraction between electrons exists in all the cuprates and could help in understanding superconductivity in the 2D versions of the Hubbard model and its kin, giving scientists a more complete picture of these puzzling materials.
