Layer-tunable Hubbard bands probed via moiré excitons in MoSe/WS heterostructures
Hongyu Yao, Qiao Li, Chih-En Hsu +5
Moiré superlattices in transition metal dichalcogenide heterostructures provide a highly tunable platform for engineering strongly interacting states at the nanoscale. However, qu…
Fractional quantum anomalous Hall and anyon density-wave halo in a minimal interacting lattice model of twisted bilayer MoTe
Chuyi Tuo, Ming-Rui Li, Hong Yao
The experimental discovery of fractional quantum anomalous Hall (FQAH) states in tunable moiré superlattices has sparked intense interest in exploring the interplay between topolo…
Theory of Topological Superconductivity and Antiferromagnetic Correlated Insulators in Twisted Bilayer WSe
Chuyi Tuo, Ming-Rui Li, Zhengzhi Wu +2
Since the very recent discovery of unconventional superconductivity in twisted WSe homobilayers at filling , considerable interest has arisen in revealing its mechanism.…
Berry Trashcan With Short Range Attraction:Exact Superconductivity in Rhombohedral Graphene
Ming-Rui Li, Yves H. Kwan, Hong Yao +1
We show the presence of analytic superconducting ground states in the Berry Trashcan -- a minimal model of rhombohedral graphene valid for layers -- under s…
Emergent Interacting Phases in the Strong Coupling Limit of Twisted M-Valley Moiré Systems: Application to SnSe
Ming-Rui Li, Dumitru Calugaru, Yi Jiang +10
We construct an interacting Wannier model for both AA-stacked and AB-stacked twisted SnSe2, revealing a rich landscape of correlated quantum phases. For the AA-stacked case, the sy…
Single-band Triangular Lattice Hubbard Model with Tunable Anisotropy from Twisted Diamond Homobilayers
Wen Sun, Chuyi Tuo, Hong Yao
The ground-state properties of the single-band triangular lattice Hubbard model with hopping anisotropy and strong interactions remain elusive so far. Here we show that twisted dia…
