Beyond the Flat-Band Paradigm: Open Orbits as a Route to Correlated States in Dispersive Moir\'e Minibands

The realization of fractional Chern insulators has largely relied on isolated flat bands in complex bilayer or multilayer moir\'e systems with ideal quantum geometry. Whether such phases can emerge in genuinely dispersive bands, and by what mechanism, remains an open question. Here, we propose a mechanism for magnetic-...
