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…

Tuning competition between charge order and superconductivity in the square-lattice -- model
Xin Lu, Huaiming Guo, Wei-Qiang Chen +2
Recently, a flurry of works have found strong competition between charge density wave (CDW) and superconductivity (SC) in the doped Hubbard and - models on the square lattice…
