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…
