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…
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…
