Charge-4e/6e superconductivity and chiral metal from 3D chiral superconductor
Chu-Tian Gao, Chen Lu, Yu-Bo Liu +2
Unconventional superconductivity (SC) characterized by multi-fermion orderings has attracted substantial attention. However, previous studies have largely focused on 2D systems or…

Van Hove singularity-induced multiple magnetic transitions in multi-orbital systems
Chen Lu, Lun-Hui Hu
Van Hove singularities (VHSs) amplify electronic correlations, providing a crucial platform for discovering novel quantum phase transitions. Here, we show that VHSs in multi-orbita…
