Orbital-selective electron correlations in high- bilayer nickelates: from a global phase diagram to implications for spectroscopy
Zhiguang Liao, Yiming Wang, Lei Chen +3
Motivated by the high temperature superconductivity observed in the bilayer nickelate LaNiO and the spectroscopic evidences of strong electron correlations in this comp…
Fully nonequilibrium Hall response from Berry curvature
Shouvik Sur, Lei Chen, Yiming Wang +3
In topological materials, Berry curvature leads to intrinsic Hall responses. Focusing on time-reversal symmetric systems with broken inversion symmetry, a spontaneoous (zero magnet…
Persistent flat band splitting and strong selective band renormalization in a kagome magnet thin film
Zheng Ren, Jianwei Huang, Hengxin Tan +21
Magnetic kagome materials provide a fascinating playground for exploring the interplay of magnetism, correlation and topology. Many magnetic kagome systems have been reported inclu…
Superconductivity in twisted WSe from topology-induced quantum fluctuations
Fang Xie, Lei Chen, Shouvik Sur +3
Recently, superconductivity has been observed in twisted WSe moiré structures (Xia et al., Nature 2024; Guo et al., Nature 2025). Its transition temperature is high, reaching a…
Topological Kondo semimetals emulated in hetero-bilayer transition metal dichalcogenides
Fang Xie, Lei Chen, Yuan Fang +1
The moiré structure of AB-stacked represents a natural platform to realize Kondo lattice models, due to the discrepancy of the bandwidth between the individual…
Electron correlations in the kagome flat band metal
Fang Xie, Yuan Fang, Ying Li +7
Kagome metals offer a unique platform for investigating robust electron-correlation effects because of their lattice geometry, flat bands and multi-orbital nature. In the cases wit…
Magnetic Weyl-Kondo semimetals induced by quantum fluctuations
Yuan Fang, Lei Chen, Andrey Prokofiev +5
Weyl-Kondo semimetals are strongly correlated topological semimetals that develop through the cooperation of the Kondo effect with space group symmetries. The Kondo effect, capturi…
Amplified multipartite entanglement witnessed in a quantum critical metal
Yuan Fang, Mounica Mahankali, Yiming Wang +4
Strong correlations in matter promote a landscape of quantum phases and associated quantum critical points. For metallic systems, there is increasing recognition that the quantum c…
Dirac zeros in an orbital selective Mott phase: Green's function Berry curvature and flux quantization
Lei Chen, Haoyu Hu, Maia G. Vergniory +2
How electronic topology develops in strongly correlated systems represents a fundamental challenge in the field of quantum materials. Recent studies have advanced the characterizat…
