Pressure-induced decoupling of the pseudogap and superconductivity in a bilayer cuprate
Yanghao Meng, Wenjin Mao, Liucheng Chen +8
The physical origin of the pseudogap in cuprate superconductors, whether a precursor to superconductivity or a distinct intertwined order, remains an open question. Although hydros…

Imaging magnetic flux trapping in lanthanum hydride using diamond quantum sensors
Yang Chen, Junyan Wen, Ze-Xu He +7
Lanthanum hydride has attracted significant attention in recent years due to its signatures of superconductivity at around 250 K (1, 2). However, the megabar pressures required for…
