Ferromagnetism from the geometry of localized wavefunctions in moiré systems
Miguel Gonçalves, Sarang Gopalakrishnan
We present a mechanism for ferromagnetism in narrow bands consisting of Anderson-localized states. We exploit single-particle localization to derive a controlled theory of exchange…

Chiral skyrmionic superconductivity from doping a Chern Ferromagnet
Miguel Gonçalves, Kun Yang, Shi-Zeng Lin
We show that chiral superconductivity can be stabilized by hole doping a Chern ferromagnet. Performing exact diagonalization and density-matrix-renormalization-group calculations o…

Observation of High-Temperature Dissipationless Fractional Chern Insulator
Heonjoon Park, Weijie Li, Chaowei Hu +13
The fractional quantum anomalous Hall effect has recently been experimentally observed in zero-field fractional Chern insulators (FCI). However, an outstanding challenge is the pre…
