Ferromagnetism and insulating behavior with a logarithmic temperature dependence of resistivity in
Yuhang Zhang, Cong Liu, Xiyu Zhu +1
Recent claim of discovering above-room-temperature superconductivity (Tc about 400 K) at ambient pressure in copper doped apatite has stimulated wo…
Electronic correlations and partial gap in the bilayer nickelate LaNiO
Zhe Liu, Mengwu Huo, Jie Li +8
The discovery of superconductivity with a critical temperature of about 80~K in LaNiO single crystals under pressure has received enormous attention. LaNi$_…
Significant improvement of the lower critical field in Y doped Nb: potential replacement of basic material for the radio-frequency superconducting cavity
Wei Xie, Yu-Hao Liu, Xinwei Fan +1
The research of high energy and nuclear physics requires high power accelerators, and the superconducting radio-frequency (SRF) cavity is regarded as their engine. Up to now, the w…
Pressure-induced color change arising from transformation between intra- and inter-band transitions in LuHN
Zhe Liu, Yingjie Zhang, Shenyang Huang +8
The pressure-induced color change in the nitrogen-doped lutetium hydride has triggered extensive discussions about the underlying physics. Here, we study the optical response of Lu…
Pressure induced color change and evolution of metallic behavior in nitrogen-doped lutetium hydride

Absence of near-ambient superconductivity in LuHN
Xue Ming, Ying-Jie Zhang, Xiyu Zhu +6
Recently near-ambient superconductivity was claimed in N-doped lutetium hydride (ref. 1). This induces a worldwide fanaticism about the dream of room temperature superconductivity…
Real-space pairing through a confined local nematic state in cuprate superconductors
