Twisted two-dimensional semiconductors provide a route to flat and topological moir´e minibands, but systematic principles for organizing their material dependence have remained unclear. Here, we establish a high-throughput framework that integrates structural relaxation, first-principles electronic structure calculations, and moiré band topology. We apply this framework to 43 experimentally...

Fractionalization and anyon superconductivity are fascinating concepts in modern condensed matter physics, dating back to the 1980s and the work of Laughlin and others. The recent experimental discovery of the zero-field fractional Chern insulator (FCI) and of superconductivity provides renewed motivation for these questions. In this talk, I will present recent work on FCIs and anyon...

Topological flat bands (FBs) offer an ideal platform for realizing exotic topological phases and exploringquantum geometric effects, yet their realization with both exact flatness and stable topology in local latticemodels has been long hindered by fundamental no-go theorems. The obstruction to topological FBs is alsomanifested as the absence of exact Gaussian tensor-network state (TNS)...
