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…
Compression-induced magnetic obstructed atomic insulator and spin singlet state in antiferromagnetic KV2Se2O
Liucheng Chen, Jiayi Yue, Jingwen Cheng +8
Among the complex many-body systems, the metal-insulator transition stands out as a cornerstone and a particularly fertile ground for scientific inquiry. The established models inc…
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…
Hidden phonon-assisted charge density wave transition in BaFe2Al9 revealed by ultrafast optical spectroscopy
Lei Wang, Mingwei Ma, Jiangxu Li +10
The interplay between electronic and lattice degrees of freedom is fundamental to charge density wave (CDW) formation, yet the microscopic origin often remains elusive. Here, we in…
Unconventional charge density wave in Kagome metal BaFe2Al9
Liucheng Chen, Mingwei Ma, Xiaohui Yu +1
The charge density wave (CDW) is a macroscopic quantum state characterized by long-range lattice distortion and modulated charge density. Conventionally, CDWs compete with other el…
Imaging the Meissner effect in pressurized bilayer nickelate with integrated multi-parameter quantum sensor
Junyan Wen, Yue Xu, Gang Wang +14
Recent reports on the signatures of high-temperature superconductivity with a critical temperature Tc close to 80 K have triggered great research interest and extensive follow-up s…
Density-wave-like gap evolution in LaNiO under high pressure revealed by ultrafast optical spectroscopy
Yanghao Meng, Yi Yang, Hualei Sun +8
Density wave (DW) order is believed to be correlated with superconductivity in the recently discovered high-temperature superconductor LaNiO. However, experimental inve…
