Topological Chiral Superconductivity in the Triangular-Lattice Hofstadter-Hubbard Model
Feng Chen, Wen O. Wang, Jia-Xin Zhang +2
Moiré materials provide exciting platforms for studying the interplay of strong electronic correlation and large magnetic flux effects. We study the lightly doped Hofstadter-Hubba…

Robust non-Abelian even-denominator fractional Chern insulator in twisted bilayer MoTe
Feng Chen, Wei-Wei Luo, Wei Zhu +1
A recent experiment observes a series of quantum spin Hall effects in transition metal dichalcogenide moiré MoTe [K. Kang, et. al, Nature 628, 522-526 (2024)]. Among them, the…
