Magnetic fluctuations near the Van Hove singularity in the kagome-lattice Hubbard model at finite doping
Jingyao Wang, Zixuan Jia, Zenghui Fan +2
The kagome-lattice Hubbard model attracts widespread interest due to its flat-band and Van Hove singularity features, which can give rise to unconventional magnetism. We employ det…

Magnetic correlations and superconducting pairing near higher-order Van Hove singularities
Zheng Wei, Yanmei Cai, Boyang Wen +1
Higher-order Van Hove singularities in strongly correlated electron systems provide a fertile ground for emergent electronic orders and superconductivity. This study investigates t…
