Ideal Topological Flat Bands in Two-dimensional Moiré Heterostructures with Type-II Band Alignment
Yunzhe Liu, Anoj Aryal, Kaijie Yang +6
Topological flat bands play an essential role in inducing exotic interacting physics, ranging from fractional Chern insulators to superconductivity, in moiré materials. In this wor…

Nodal Nematic Superconductivity in Multiple-Flat-Band Land
Chao-Xing Liu, B. Andrei Bernevig
In this work, we propose a mechanism of inducing stable nodal superconductivity for multiple-flat-band systems. This mechanism is based on the degenerate flat band nature, so that…

Topological Heavy Fermion Principle For Flat (Narrow) Bands With Concentrated Quantum Geometry
Jonah Herzog-Arbeitman, Jiabin Yu, Dumitru Călugăru +8
We propose a general principle for the low-energy theory of narrow bands with concentrated Berry curvature and Fubini-Study metric in the form of a map to Anderson-"+" models compo…
