Quantum-geometry-enabled Landau-Zener tunneling in singular flat bands
Xuanyu Long, Feng Liu
Flat-band materials have attracted substantial interest for their intriguing quantum geometric effects. Here we investigate how singular flat bands (SFBs) respond to a static, unif…

Interplay of quantum and real-space geometry in the anomalous Landau levels of singular flat bands
Xuanyu Long, Feng Liu
Quantum geometry of electronic state in momentum space, distinct from real-space structural geometry, has attracted increasing interest to shed light on understanding quantum pheno…
