Intertwined spin-charge stripe order and polar lattice distortion in LaNiO
Xiaoying Li, Wenqian Tu, Run Lv +4
The low-temperature density-wave state of LaNiO hosts pronounced spin-density-wave (SDW) order, while recent experiments further reveal charge redistribution and a conc…
Three-dimensional Ising superconductors designed via inversion-symmetry breaking in intercalated NbSe and NbTe
Wenqian Tu, Run Lv, Xiaoying Li +4
Ising superconductors exhibit in-plane upper critical fields far exceeding the Pauli paramagnetic limit, a hallmark first established in two-dimensional (2D) monolayer transition-m…
Machine learning-accelerated search of superconductors in B-C-N based compounds and R3Ni2O7-type nickelates
Xiaoying Li, Wenqian Tu, Run Lv +4
Superconductor research has traditionally depended on experiments and theoretical approaches. However, the rapid advancement of data-driven methods and machine learning (ML) has op…
Orbital-selective two-gap superconductivity in kagome metal CsV3Sb5
Run Lv, Wenqian Tu, Dingfu Shao +2
Recent experiments have revealed anisotropic multi-gap superconductivity in the kagome metal CsV3Sb5. However, the impact of multi-orbital character and electron-phonon coupling (E…
Phonon anharmonicity-driven charge density wave transition and ultrafast dynamics in 1T-TaS2/TaSe2
Wenqian Tu, Run Lv, Dingfu Shao +2
Charge density wave (CDW), a symmetry-breaking collective phenomenon in condensed matter systems, exhibits periodic modulations of electron density coupled with lattice distortions…
Strain tuning of charge density wave and Mott-insulating states in monolayer VTe2
Wenqian Tu, Run Lv, Dingfu Shao +2
Monolayer vanadium ditelluride (VTe2) exhibits a 2\sqrt{3}*2\sqrt{3} charge density wave (CDW) order intertwined with a Mott-insulating state. However, the physical mechanisms driv…
Symmetry-Broken Kondo Screening and Zero-Energy Mode in the Kagome Superconductor CsV3Sb5
Yubing Tu, Zongyuan Zhang, Wenjian Lu +9
The quantum states of matter reorganize themselves in response to defects, giving rise to emergent local excitations that imprint unique characteristics of the host states. While m…
Physical origin of color changes in lutetium hydride under pressure
Run Lv, Wenqian Tu, Dingfu Shao +2
Recently, near-ambient superconductivity was claimed in nitrogen-doped lutetium hydride (LuHN) . Unfortunately, all follow-up research still cannot find superconductivi…
