High-energy electronic excitations in La3Ni2O7 by time-resolved optical spectroscopy
Junzhi Zhu, Mengwu Huo, Yubin Wang +11
Recently, high-temperature superconductivity has been established in bilayer La3Ni2O7, which exhibits a density-wave (DW) transition at ~ 150 K under ambient pressure. The DW order…
