Higher-Winding Fractionalization
Kishore Iyer, Christophe Mora, Daniele Guerci
Higher-winding skyrmion textures can generate emergent magnetic fields with multiple flux quanta per unit cell. This opens an intriguing route toward fractionalization, allowing fr…

Dispersion of Anyon Bloch Bands
Kishore Iyer, Andreas Feuerpfeil, Valentin Crépel +2
Fractional Chern insulators (FCIs) are zero magnetic field analogs of fractional quantum Hall states. While the electrons forming an FCI are not subject to an external magnetic fie…

Layer skyrmions for ideal Chern bands and twisted bilayer graphene
Daniele Guerci, Jie Wang, Christophe Mora
Ideal Chern bands exhibit a Landau level correspondence: they factorize as a lowest Landau levels and a spinor wavefunction that spans the layer index. We demonstrate that, i…
