Nagaoka supermetal in the particle-doped triangular Hubbard model
Rui Cao, Xiangyue Zhang, Hui Tan +4
While the interplay of correlations and geometric frustration in doped Mott insulators provides a fertile ground for exotic quantum phases, the nature of the metallic state emergin…

Surface reconstruction and orthogonal decoupling in SrAl4 and EuAl4
Tongrui Li, Leiyuan Chen, Jian Yuan +10
Surface-induced symmetry breaking in quantum materials can stabilize exotic electronic phases distinct from those in the bulk, yet its momentum-space manifestations remain elusive…
