Observation of Flat Band and Van Hove Singularity in Non-superconducting Nitrogen-doped Lutetium Hydride
Xin Liang, Zihan Lin, Jun Zhang +15
Hydrogen-rich materials offer a compelling avenue towards room temperature superconductivity, albeit under ultra-high pressure. However, the experimental investigation of the elect…
Emergence of high-temperature superconducting phase in the pressurized La3Ni2O7 crystals
J. Hou, P. T. Yang, Z. Y. Liu +12
The recent report of pressure-induced structure transition and signature of superconductivity with Tc = 80 K above 14 GPa in the La3Ni2O7 crystals has garnered considerable attenti…
Pressure tuning of optical reflectivity in LuH2
Xuan Zhao, Pengfei Shan, Ningning Wang +3
Recently, the claim of room-temperature superconductivity in nitrogen-doped lutetium hydride at near-ambient conditions has attracted tremendous attention. Criticism of the work ri…
Pressure-induced color change in the lutetium dihydride LuH2
Pengfei Shan, Ningning Wang, Xiquan Zheng +3
The lutetium dihydride LuH2 is stable at ambient conditions. Here we show that its color undergoes sequential changes from dark blue at ambient pressure to pink at ~2.2 GPa and the…
