Signatures of unconventional superconductivity near reentrant and fractional quantum anomalous Hall insulators
Fan Xu, Zheng Sun, Jiayi Li +18
Two-dimensional moiré Chern bands provide an exceptional platform for exploring a variety of many-body quantum phases at zero magnetic field within a lattice system. One particula…
Twist-angle evolution from valley-polarized fractional topological phases to valley-degenerate superconductivity in twisted bilayer MoTe2
Zheng Sun, Fan Xu, Jiayi Li +16
Moiré superlattices formed by semiconducting transition metal dichalcogenides (TMDs) provide a highly tunable platform for investigating strongly correlated and topological quantu…
From fractional Chern insulators to topological electronic crystals in moiré MoTe2: quantum geometry tuning via remote layer
Feng Liu, Fan Xu, Cheng Xu +18
The quantum geometry of Bloch wavefunctions,encoded in the Berry curvature and quantum metric, is believed to be a decisive ingredient in stabilizing fractional quantum anomalous H…
Interplay between topology and correlations in the second moiré band of twisted bilayer MoTe2
Fan Xu, Xumin Chang, Jiayong Xiao +17
Topological flat bands formed in two-dimensional lattice systems offer unique opportunity to study the fractional phases of matter in the absence of an external magnetic field. Cel…
